Introduction
The exact zodiac degree (minutes and seconds) that is rising in the eastern
horizon at the time of birth is called Janma Lagnam or Ascendant. The zodiac degree that
is at the zenith (exactly overhead 900 to the horizon) at the time of birth is the 10th
house, mid-heaven or the meridian cusp. As the entire zodiac consisting of 12 signs
describes a great celestial circle of 3600, each sign comprises 300 of zodiac arc and all the
12 houses (cusps or Bhavas) fall within these 12 signs. For example, if one says at the
time of birth 215th degree of zodiac sign was rising in the eastern horizon, we say birth
took place during Vrischika laganm as the zodiac sign Vrischikam is assigned an arc
between 2100 and 2400. The twelve zodiac signs and their arc span are given in the table
below.

It may be mentioned that as the earth takes 24 hours to rotate on its axis, all the
12 zodiac signs would be rising in the eastern horizon sequentially one after another in
24 hours. That is to say each sign of 300 takes about 2 hours to come up entirely, all the
12 signs taking 24 hours. For example, as a thumb rule, around April 15 of every year,
00 of zodiac (Mesham) will be rising at the eastern horizon along with Ravi. Let us
suppose that Sunrise on that day is at 6:00 AM; then by 8:00 AM, the entire Mesham
would have risen. For next two hours (up to 10:00 AM) the sign Vrishabham rises and if
birth occurs during this time interval, Janma Lagnam will be Vrishabham. The sequence

continues. Thus depending on the time of reckoning, whichever sign would be rising in
the eastern horizon, becomes Lagnam at that time.
(In this notes, whenever the term minutes is mentioned, it refers to time. The term arc minutes
refers to the measure of zodiac arc in space.)
Ravi (the Sun) also traverses through the zodiac. But unlike the earth, Ravi is a
slow moving Graha (Planet) and travelling about 10 (57 arc minutes to 63 arc minutes) of
zodiac per day, takes nearly one year to complete one cycle. That is Ravi will be in any
zodiac sign for 30 days (almost one month). Usually according to Nirayana Paddhathi of
computing Panchangam, Ravi enters Mesham (Aries) around April 15 and on that day
along with Ravi 00 of zodiac (Mesham) also rises. Next day, along with Ravi 10 of Mesham
rises and the sequence continues. For next 30 days Ravi travels through the sign. Then
around May 15 He enters Vrishabham and so on. This gets repeated every year. We
know Ravi rises in East and as the zodiac sign also rises in East, along with Ravi, every
day a particular degree of zodiac will also be rising. Thus knowing the date and month it
is possible for us to identify the zodiac sign rising at the time of sunrise. Thus Ravi is a
very good zodiac keeper.
(Guess what zodiac sign would be rising on August 25.
On April 15, Ravi enters Mesham and for next 30 days He is that sign. Next 30 days He traverses
through Vrishabham. From April 15 to August 25, there are 132 days. 300 of zodiac are covered in
30 days, so in 132 days, 4 zodiac signs (a total of 1200) are already traversed by Ravi and and He
will be in the 5th sign (Simham). Depending upon the daily motion of Ravi (between 57 and 63 arc
minutes), He will be rising along with 80 to 120 of Simham.)
It should be mentioned that identification of Lagnam computed as mentioned
above is only a gross one. The reasons are many. For example, the orbiting paths of the
planets including our own earth do not describe perfect circles in space and their daily
motion is also not uniform. Added to this the very concept of time as we normally use in
our daily life also contributes to deviations. Further, as the Lagnam is the zodiac degree
rising in the Eastern horizon, the rising degree depends on the Latitude of the place.
Even for the same time, Lagnam would be different for different places depending upon
the Latitude. For accurate calculation of all the zodiac houses the positions of planets at
any given time and rigorous computations are absolutely necessary. Knowledge of
Logarithms, Trigonometry and Spherical Geometry is required. In this notes an attempt
is made to describe the methodology to be used to compute all the 12 houses in the birth
chart. The positions of the planets can be calculated using the procedures given in an
earlier book Panchangam calculations. The method described here is not entirely
manual. The computation of Star time at Birth is done manually. Then Astrological
Tables of Houses are used to compute the 12 Houses.
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 4
The concept of measurement of Time
Even though Time has the same meaning in the entire world, each Country uses
her own Standard Time concept. This is purely an administratively convenient concept
to suit the requirements of her populace for optimum use of daytime. That is why the
concept of Time Zone has been defined. To understand the concept of time zone, we
need knowledge of Longitude and standard longitude of a Country. Longitude is an
imaginary line drawn on the earth from North Pole to South Pole crossing the earths
equator. For correct identification of longitude of a place on the earth, the longitude is
always referred to a reference place. Greenwich in UK has been accepted by the entire
world as this reference point. The longitude passing through Greenwich is arbitrarily
assigned zero degrees (00) value. All the longitudes East of Greenwich are referred to
as East Longitudes and those West of Greenwich are West longitudes. For instance, our
Country India is east of Greenwich, East longitude passes through our Country. The USA
is in western hemisphere; so West longitudes pass through that Country.
As the earth rotates from West to East, Countries east of Greenwich will have
sunrise earlier than Greenwich. The Countries west of Greenwich will have sunrise later
than Greenwich. We can imagine 12 main longitudes East of Greenwich at 150 intervals
and an equal number of longitudes west of Greenwich. Thus there are 24 main
longitudinal divisions of the Earth 12 on each of Greenwich. 800 E means eighty
degrees east of Greenwich. 700 W means seventy degrees West of Greenwich. For the
sake of convenience, the world is divided into different time zones depending on the
main longitudes passing through a region. As the earth takes 24 hours for one rotation
(3600) for every 150 of change in longitude, time is changed by one hour. (3600 are
covered in 24 hours; so in one hour 3600/24 hours = 150/hour.) It is one hour ahead of
Greenwich for every 150 East of Greenwich and one hour behind of Greenwich for every
150 West of Greenwich. Each Country may have accepted one or more Longitudes
passing through her territory as standard longitudes. Time zones are expressed by
referring to these standard longitudes. India has 82.50 E as its standard longitude. Hence
our time zone is 82.50/150 x 1 h = 5h-30m east (or + 5h-30m east of Greenwich). What
it means is if it is 0:0 hours (midnight) at Greenwich, time in our Country is 5:30 AM.
Time as read at 82.50 E is our Countrys standard time. It is called Indian standard time
(IST). Similarly other Countries have their own standard longitudes and their standard
times. Large Countries like the USA and Russia have different standard longitudes on
their territories and hence different time zones. Now each Country may have sunrise
everyday around 6:00 AM. But 6:00 AM in a Country will not be 6:00 AM in other
Countries because of the time zones!
Another factor to be considered is the concept of summer time or daylight saving
time. Some Countries advance their standard time during summer by one or two hours
to save on daylight. This is called daylight saving time of summer time. During winter
they revert back to standard time. This also should be considered while computing
Lagnam.
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 5
Even though having a standard time is very convenient administrative practice for
a Country, it cannot be used for computing Lagnam. Our Country is located roughly
between 690 E (Bhuj in Gujarat) and 940 E (Kohima in Nagaland) longitudes. According to
standard longitude 82.50 E, if it is 12:00 noon, officially it is noon throughout the
Country. But the local time at a place could be different. Knowing the relation between
longitude and the time it is possible to compute local time. If at 82.50 it is 12:00 noon, in
Bhuj at 690, it would be 11:06 hrs (how?) and 12:46 hrs in Kohima (How?). These local
times are needed for computing Lagnam.
As if this is not enough, even after making all the necessary corrections to the
recorded time of birth, there is another very fundamental difficulty in accepting the same
for computing Lagnam. This arises due the way the time is measured. We define a day as
the time taken for the earth to rotate exactly 3600 on its axis. We take Ravi (the Sun) as
the reference point and the time taken by the earth to complete one rotation to come
back exactly in line with Ravi is 24 hours or one day. If we recall that during this time
Ravi would move by 10 in the cosmos, the earth has to cover that one extra degree (3610
instead of 3600) to be in line with Ravi. But if the rotation of the earth is viewed against a
distant stellar background, earth is seen to complete one rotation of 3600 in about 3m-
56s less than 24 hours as measured now. This measure is called Star Time or sidereal
time. For correct computation of Lagnam, this star time and not the familiar clock time
should be considered. In one year this difference comes to be exactly 24 hours of clock
time and both star time and clock time reference points synchronise. Next day onwards
sidereal time accelerates and moves faster than the clock time. It is thus seen that star
time is faster than clock time and this extra time needs to be added to the clock time to
keep in pace with the star time. Depending on the time of birth a proportional quantity of
3m-56s (or 3m-57s) need to be either added or subtracted. Sidereal times are normally
computed either at GMT noon or at 0:0 hrs GMT and are given in the respective
ephemeris (noon ephemeris or midnight ephemeris) along with positions of planets and
other astronomical data. We should consult them for incorporating necessary corrections
to the birth time. The sidereal time should then be corrected for the birth time and
longitude. Finally after incorporating all corrections and before proceeding to computation
of Lagnam we have to ensure that the corrected birth time is expressed in local time and
not in IST or GMT. It should be clearly understood that for House computations, we
should use local time. The final result is called Star Time at Birth (STB). This will then be
converted into arc degrees and arc minutes which is called Right Ascension to Meridian
Cusp (RAMC). Calculation of accurate star time at birth and hence RAMC is very crucial
for accurate casting of horoscope.
Another important thing to consider is whether one wants the horoscope be cast
according to Sayana Paddhathi or Nirayana paddhathi. If Nirayana horoscope is to be
cast we should subtract Ayanamsa from the longitudes of Houses obtained.
It must have become quite clear to the discerning reader that computation of sidereal
birth time and RAMC involves many factors and one should have patience to proceed
systematically to arrive at a correct value. We will take some examples to compute star

time at birth and RAMC. Then we will use the astrological tables of houses to compute all
the Houses. We will attempt to compute RAMC by using both ephemeris namely zero
hour (0:0 UT) ephemeris as well as noon (12:00 UT) ephemeris.
(In Noon Ephemeris counting of sidereal time commences from noon of March 21 every year. In
midnight ephemeris counting of sidereal time commences from midnight of September 21 every
year.)
Once we have calculated RAMC accurately, we have to use astrological tables of
houses to compute different houses (cusps or bhavas). Usually these tables of houses
are given for northern longitudes. For southern longitudes, add 12:00:00 to the RAMC if
it is less than 12 or subtract 12 from the RAMC if it is more than 12 and use the result
(new RAMC) to calculate the houses corresponding to this new value. Then subtract 1800
from each house to get the houses (bhavas or cusps) for the south longitudes (we will
solve some examples).
Example 1: Date of birth: 25-8-1952 (August 25, 1952)
Time of birth: 12:45:00, IST
Place of birth: Cuddapah, India (14:30 N, 78:47 E)
Standard longitude: 82:30 E
Day light saving time?: No

Computation based on zero hour ephemeris
Step 1: Convert IST to GMT (Use standard longitude for converting)
Standard longitude = 820:30 E =82.50
Converting this into time zone we get 82.5(deg )

Longitude is East of Greenwich.
Hence Birth time in GMT = 12:45:0 - 5:30:0 = 7:15:00 GMT
Step 2: Get the sidereal time on 25-8-1952 from ephemeris. Let us use Swiss ephemeris
for the year 1952 (see Table 2 above). Swiss ephemeris is computed for exactly 0:0 GMT
(or Universal Time UT). The sidereal time on 25-8-1952 is given as 22:12:48 at 0:0 UT.
We have to compute the sidereal time at the birth time of 7:15 GMT. This can be
obtained by ratio proportional method. On 26-8-1952, the sidereal time is given as
22:16:44. That is in 24 hours from 25th to 26th, the sidereal time is changed by 22:16:44
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 7
22:12:48 = 00:3:56 = 236 sec. Now for 24 hours change in sidereal time is 236 sec.
For 7:15:0, the change in sidereal time is 7:15:0
236sec 71.3sec 71sec24
x = = = 00:1:11
Sidereal time at birth time (GMT) = 22:12:48+00:01:11 = 22:13:59
Step 3: Compute star time at birth (at GMT). Add birth time (at GMT) and the sidereal
time at birth.
Star time at birth (GMT) = 7:15:0 + 22:13:59 = 29:28:59 (GMT)
Step 4: Convert star time at birth (GMT) to Star time at Birth (Local). Note that the
longitude to be considered is for the birth place and not the standard longitude (78:47 E
and not 82:30 E).
Star time at birth (Local) = 29:28:59 + 78: 47(deg )
5.2522215(deg / )

Subtracting 24 hrs from the result we get RAMC = 34:44:7 24:00:00 = 10:44:7
Now let us compute Lagnam and other Houses (Cusps or Bhavas). We use astrological
tables of houses for this purpose. An extract of these Tables is shown below.

For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details).
The latitude of birth place is 14:30 N and the RAMC is 10:44:7. If we look up in
the Table above, RAMC (first column) is in between 10:42 and 10:45. The latitude is in
between 14 and 15. We have to use interpolation to calculate the houses for 14:30 N and
RAMC 10:44:7.
From the Table it is seen that for a change in RAMC of 3 min (180 sec), the 10th
house changes from 158:54 to 159:42 = 48 arc min. The difference between RAMC of
10:44:7 and 10:45:00 is 53 sec. So in the period of 53 sec, the 10th house changes
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180

Similarly all the other houses are computed for RAMC of 10:44:7. These are given below.

It should be made clear that the house positions obtained as above refer to
Sayana houses. To compute Nirayana houses, we should subtract Ayanamsa for the birth
year. The Ayanamsa may be calculated using the equation:
For the beginning of the year:

Ayanamsa = A + B. The result will be in degrees. Convert into Degrees, Minutes and
Seconds. For 25-8-1952, the Ayanamsa is 23-5-34. The Nirayana Houses are:

The other houses namely 4, 5, 6, 7, 8 and 9 are exactly degreecally opposite of the
houses 10, 11, 12, Lagna, 2 and 3 respectively. In the above case, these are
respectively, Kumbham, Meenam, Mesham, Vrishabham, Mithunam and Karkatakam.
Nirayana houses are used in India for casting the horoscopes.
Now let us calculate RAMC using noon ephemeris for the example 1 given above.
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 9
Computation of RAMC based on noon hour ephemeris
Step 1: Convert IST to GMT (Use standard longitude for converting)
Standard longitude = 820:30 E =82.50
Converting this into time zone we get 82.5(deg )
5.5 5:3015(deg / )
reeshr
rees hr= =
Longitude is East of Greenwich.
Hence Birth time in GMT = 12:45:0 - 5:30:0 = 7:15:00 GMT
As the birth occurred before noon, add 12:00:00 to get adjusted birth time: 12:00:00 +
7:15:00 = 19:15:00 GMT.
Step 2: In the above case, as we have added 12:00:00, take the sidereal time on the
previous day of the birth day. In this case it is 24-8-1952. The sidereal time on 24-8-
1952 is given as 10:10:49 at 12:00 UT. We have to compute the sidereal time at the
birth time of 19:15 GMT. This can be obtained by ratio proportional method. On 25-8-
1952, the sidereal time is given as 10:14:46. That is in 24 hours from 24th to 25th, the
sidereal time is changed by 10:14:46 10:10:49 = 00:3:57 = 237 sec. Now for 24
hours change in sidereal time is 237 sec. For 19:15:0, the change in sidereal time is
19:15:0237sec 190.1sec 190sec

Sidereal time at birth time (GMT) = 10:10:49+00:03:10 = 10:13:59
Step 3: Compute star time at birth (at GMT). Add birth time (at GMT) and the sidereal
time at birth.
Star time at birth (GMT) = 19:15:0 + 10:13:59 = 29:28:59 (GMT)
Step 4: Convert star time at birth (GMT) to Star time at Birth (Local). Note that the
longitude to be considered is for the birth place and not the standard longitude (78:47 E
and not 82:30 E).
Star time at birth (Local) = 29:28:59 + 78 : 47(deg )

So which ever may the ephemeris one uses, RAMC for a given birth time, date and place
should be identical.
Use the method given above to compute the Houses.
Example 2: Date of birth: 25-8-1952 (August 25, 1952)
Time of birth: 12:45:00, LST
Place of birth: XXXXX, YYYYY (14:30 N, 78:47 W)
Standard longitude: 82:30 W
Day light saving time?: No
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 10
Notice that birth time is given in Local standard time. The place is west of Greenwich
(78:47 W and standard longitude is 82:30 W).
Computation based on zero hour ephemeris
Step 1: Convert LST to GMT (Use of standard longitude)
Standard longitude = 820:30 W =82.50
Converting this into time zone we get 82.5(deg )

Longitude is West of Greenwich.
Hence Birth time in GMT = 12:45:0 + 5:30:0 = 18:15:00 GMT
Step 2: Get the sidereal time on 25-8-1952 from ephemeris (see Table 1). The sidereal
time on 25-8-1952 is given as 22:12:48 at 0:0 UT. We have to compute the sidereal
time at the birth time of 18:15 GMT. On 26-8-1952, the sidereal time is given as
22:16:44. That is in 24 hours from 25th to 26th, the sidereal time is changed by 22:16:44
22:12:48 = 00:3:56 = 236 sec. Now for 24 hours change in sidereal time is 236 sec.
For 7:15:0, the change in sidereal time is 18:15:0

Sidereal time at birth time (GMT) = 22:12:48+00:03:00 = 22:15:48
Step 3: Compute star time at birth (at GMT). Add birth time (at GMT) and the sidereal
time at birth.
Star time at birth (GMT) = 18:15:0 + 22:15:48 = 40:30:48 (GMT)
Step 4: Convert star time at birth (GMT) to Star time at Birth (Local). Note that the
longitude to be considered is for the birth place and not the standard longitude (78:47 W
and not 82:30 W).
Star time at birth (Local) = 40:30:48 - 78 : 47(deg )

As it is more than 24, subtracting 24 hrs from the result we get
RAMC = 35:15:40 24:00:00 = 11:15:40
Use the method given for example 1 to compute the Houses.
Computation of RAMC based on noon hour ephemeris
Step 1: Convert LST to GMT (Use of standard longitude)
Standard longitude = 820:30 W =82.50
Converting this into time zone we get 82.5(deg )

Longitude is West of Greenwich.
Hence Birth time in GMT = 12:45:0 + 5:30:0 = 18:15:00 GMT
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 11
As the birth occurred after noon, subtract 12:00:00 from the birth time to get adjusted
birth time: 18:15:00 - 12:00:00 = 6:15:00 GMT.
Step 2: Get the sidereal time at noon GMT on 25-8-1952 from ephemeris (see Table 1
above.) On 25-8-1952, the sidereal time at noon is given as 10:14:46. We have to
compute the sidereal time at the birth time of 6:15 GMT. On 26-8-1952, the sidereal
time is given as 10:18:42. That is in 24 hours from 25th to 26th, the sidereal time is
changed by 10:18:42 10:14:46 = 00:3:56 = 236 sec. Now for 24 hours change in
sidereal time is 236 sec. For 6:15:0, the change in sidereal time is

24x = = = 00:01:02
Sidereal time at birth time (GMT) = 10:14:46+00:01:02 = 10:15:48
Step 3: Compute star time at birth (at GMT). Add birth time (at GMT) and the sidereal
time at birth.
Star time at birth (GMT) = 6:15:00 + 10:15:48 = 16:30:48 (GMT)
Step 4: Convert star time at birth (GMT) to Star time at Birth (Local). Note that the
longitude to be considered is for the birth place and not the standard longitude (78:47 W
and not 82:30 W).
Star time at birth (Local) = 16:30:48 - 78: 47(deg )

Step 2: Get the sidereal time on 25-8-1952 from ephemeris (Table 1). The sidereal time
on 25-8-1952 is given as 22:12:48 at 0:0 UT. We have to compute the sidereal time at
the birth time of 18:15 GMT. On 26-8-1952, the sidereal time is given as 22:16:44. That
is in 24 hours from 25th to 26th, the sidereal time is changed by 22:16:44 22:12:48 =

Star time at birth (GMT) = 18:15:0 + 22:15:48 = 40:30:48 (GMT)
Step 4: Convert star time at birth (GMT) to Star time at Birth (Local). Note that the

rees hr=
=40:30:48 - 5:15:8 = 35:15:40
As it is more than 24, subtracting 24 hrs from the result we get
35:15:40 24:00:00 = 11:15:40
As it is south latitude, add 12:0:0 to the result to get
New RAMC = 11:15:40 + 12:00:00 = 23:15:40
Now let us compute Lagnam and other houses for this South latitude.
The latitude of birth place is 14:30 N and the new RAMC is 23:15:40. If we look up
in the Table 3, RAMC (first column) is in between 23:15 and 23:18. The latitude is in
between 14 and 15. We have to use interpolation to calculate the houses for 14:30 N and
RAMC 23:15:40.
From the Table it is seen that for a change in RAMC of 3 min (180 sec), the 10th
house changes from 347:46 to 348:35 = 49 arc min. The difference between new RAMC
of 23:15:40 and 23:15:00 is 40 sec. So in the period of 40 sec, the 10th houses changes
by40
X49 10.888 11arcmin.180
= = This should be added to the 10th house value at 23:15
to get 10th house for new RAMC.
10th house = 347:46 + 00:11 = 347:57
Similarly all the other houses are computed for new RAMC of 23:15:40. These are
given below.
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 13

Recall that we are dealing with south latitude. What we obtained is the houses 4, 5, 6,
7, 8 and 9. To get the correct houses (10, 11, 12, Lagna, 2 and 3) add 1800 to the house
if it is less than 1800 or subtract 1800 if the value is more than 1800. This exercise results
are shown in the last column in the above Table.
It should be made clear that the house positions obtained as above refer to Sayana
houses. To compute Nirayana houses, we should subtract Ayanamsa for the birth year.
The Ayanamsa may be calculated using the equation:
For the beginning of the year:
6.92416 16.90709 0.7573711000 10001000
year year yearA = +
1.15740741
30 1000
DayB Month x
= +
Ayanamsa = A + B. The result will be in degrees. Convert into Degrees, Minutes and
Seconds. For 25-8-1952, the Ayanamsa is 23-5-34. The Nirayana Houses are:
House House Sayana system Nirayana system

Note: For South Latitudes, proceed up to the final result of step 4. Then add 12:0:0 to the result to
get new RAMC. Compute the houses for this new RAMC. Add or subtract 1800 from each house
value to get the correct houses.
Computation of RAMC based on noon hour ephemeris
Step 1: Convert LST to GMT (Use of standard longitude)
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180

(if it is more) to each house to get the house cusps. (See the main text for details). Page 14

Longitude is West of Greenwich.
Hence Birth time in GMT = 12:45:0 + 5:30:0 = 18:15:00 GMT
As the birth occurred after noon, subtract 12:00:00 from the birth time to get adjusted
birth time: 18:15:00 - 12:00:00 = 6:15:00 GMT.
Step 2: Get the sidereal time at noon GMT on 25-8-1952 from ephemeris (see Table 1
above.) On 25-8-1952, the sidereal time at noon is given as 10:14:46. We have to
compute the sidereal time at the birth time of 6:15 GMT. This can be obtained by ratio
proportional method. On 26-8-1952, the sidereal time is given as 10:18:42. That is in 24
hours from 25th to 26th, the sidereal time is changed by 10:18:42 10:14:46 = 00:3:56
= 236 sec. Now for 24 hours change in sidereal time is 236 sec. For 6:15:0, the change
in sidereal time is 6 :15: 0

Step 3: Compute star time at birth (at GMT). Add birth time (at GMT) and the sidereal
time at birth.
Star time at birth (GMT) = 6:15:00 + 10:15:48 = 16:30:48 (GMT)
Step 4: Convert star time at birth (GMT) to Star time at Birth (Local). Note that the
longitude to be considered is for the birth place and not the standard longitude (78:47 W
and not 82:30 W).
Star time at birth (Local) = 16:30:48 - 78: 47(deg )

As it is south latitude, add 12:0:0 to the result to get

So which ever may the ephemeris one uses, RAMC for a given birth time, date and place
should be identical. Proceed for computation of houses as described in the example 3.
Example 4: Date of birth: 25-8-1952 (August 25, 1952)
Time of birth: 12:45:00, LST
Place of birth: SSSSS, TTTTT (14:30 S, 78:47 E)

Hence Birth time in GMT = 12:45:0 - 5:30:0 = 7:15:00 GMT
Step 2: Get the sidereal time on 25-8-1952 from ephemeris. Let use Swiss ephemeris for
the year 1952 (see Table 2 above). Swiss ephemeris is computed for exactly 0:0 GMT (or
Universal Time UT). The sidereal time on 25-8-1952 is given as 22:12:48 at 0:0 UT. We
have to compute the sidereal time at the birth time of 7:15 GMT. This can be obtained by
ratio proportional method. On 26-8-1952, the sidereal time is given as 22:16:44. That is
in 24 hours from 25th to 26th, the sidereal time is changed by 22:16:44 22:12:48 =

x = = = 00:1:11
Sidereal time at birth time (GMT) = 22:12:48+00:01:11 = 22:13:59
Step 3: Compute star time at birth (at GMT). Add birth time (at GMT) and the sidereal
time at birth.
Star time at birth (GMT) = 7:15:0 + 22:13:59 = 29:28:59 (GMT)
Step 4: Convert star time at birth (GMT) to Star time at Birth (Local). Note that the
longitude to be considered is for the birth place and not the standard longitude (78:47 E
and not 82:30 E).
Star time at birth (Local) = 29:28:59 + 78 : 47(deg )

As it is south latitude, add 12:0:0 to the result to get
RAMC = 10:44:7 + 12:00:00 = 22:44:7
Proceed for computation of houses as described in the example 3.
Computation of RAMC based on noon hour ephemeris
Step 1: Convert IST to GMT (Use of standard longitude)
Standard longitude = 820:30 E =82.50
Converting this into time zone we get 82.5(deg )

(if it is more) to each house to get the house cusps. (See the main text for details). Page 16
Hence Birth time in GMT = 12:45:0 - 5:30:0 = 7:15:00 GMT
As the birth occurred before noon, add 12:00:00 to get adjusted birth time: 12:00:00 +
7:15:00 = 19:15:00 GMT.
Step 2: In the above case, as we have added 12:00:00, take the sidereal time on the
previous day of the birth day. In this case it is 24-8-1952. The sidereal time on 24-8-
1952 is given as 10:10:49 at 12:00 UT. We have to compute the sidereal time at the
birth time of 19:15 GMT. This can be obtained by ratio proportional method. On 25-8-
1952, the sidereal time is given as 10:14:46. That is in 24 hours from 24th to 25th, the
sidereal time is changed by 10:14:46 10:10:49 = 00:3:57 = 237 sec. Now for 24
hours change in sidereal time is 237 sec. For 19:15:0, the change in sidereal time is

time at birth.
Star time at birth (GMT) = 19:15:0 + 10:13:59 = 29:28:59 (GMT)
Step 4: Convert star time at birth (GMT) to Star time at Birth (Local). Note that the
longitude to be considered is for the birth place and not the standard longitude (78:47 E

Subtracting 24 hrs from the result we get 44:44:7 24:00:00 = 10:44:7
As it is south latitude, add 12:0:0 to the result to get
RAMC = 10:44:7 + 12:00:00 = 22:44:7
So which ever may the ephemeris one uses, RAMC for a given birth time, date and place
should be identical. Proceed for computation of houses as described in the example 3.
In some countries during summer the clock time is advanced by one or two hours to save
on day light. This is called summer time or day light saving time. The standard longitude
is not changed and remains same and with respect this standard longitude the time
difference from GMT also remains the same. One should be vigilant and subtract the
number of hours as the case may be from the birth time and proceed with casting
of horoscope. Summer time concept is purely an administrative convenience. This should
never be used for horoscope casting.
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 17
Summary and important points to be noted while computing Houses
1. Note down the birth time, Latitude and Longitude of the birth place and standard
Longitude
2. If summer time is being followed and day light saving time is used, subtract this
time (no. of hours of daylight saving as announced by the Administration) from the
birth time.
3. House cusps shall always be calculated for the Local time.
4. Have the ephemeris (either noon or midnight) containing sidereal time and the
positions of the planets and astrological tables of houses.
5. For South latitudes follow the principle of forward RAMC by 12, compute and
retreat by 1800 to get cusps. That is add 12:00:00 to the RAMC to get new RAMC.
Compute the houses and add or subtract 1800 from the cusps.
There could be other methods of RAMC computation. But I found the method described
here is relatively easy with minimum corrections. Converting the birth time to GMT and
carrying out all calculations to get RAMC at GMT and then converting the final result to
RAMC at LMT is very easy.
Carrying out computations at LMT is somewhat elaborate in the sense that not only
longitudinal corrections for birth time but also corrections to sidereal time (longitudinal
correction and accelerator or Doppler correction) need to be carried out.
One may use the method described in my earlier book Panchangam calculations to
calculate longitudes of Grahas (Planets). In this monograph, the computation of House
longitudes is given. The Astrological Tables of Houses required for this purpose is being
given in four parts. The first part covering Latitudes 0 N to 14 N is included in this
monograph. I have followed the method described by Alan Leo in his book The
Progressed Horoscope. House cusps have been calculated using Quick Basic Language.
Double precision mode was used to increase the accuracy in calculations.
For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 18

For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 20

For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 22

For Sothern Latitudes, add 12:0:0 to the RAMC. Compute the houses and then add 1800 (if less than 180
0) or subtract 180
0
(if it is more) to each house to get the house cusps. (See the main text for details). Page 23
