You’re sitting in class idly recalling the entire Table of Elements

forwards and backwards, then your teacher announces your next

examination will be held on March 9

You glance up and murmur quietly. “That’s a Monday, isn’t it?”

And when the calendar is checked,

you’re right! What’s more,

you can reel off, almost instantly,

the day of any date throughout

the year.

How’s it done?

It requires a little preparation.

Find a calendar and use it to

discover the dates of the first

Sunday of each month

throughout the year.

In 2015, for example, the first

Sunday of January is on

January 4, the first Sunday of

February is February 1, the

first Sunday of March is

March 1, the first Sunday of

April is April 5 and so on.

Write down the numbers of those first Sundays, giving you a

twelve digit number for the year. In 2015 that twelve digit

number is:

411537526416

Now, use your own technique to memorise that one. When

you have it burned in, you’re ready.

When the teacher tells you the next examination is on March 9,

you consult your memorised number and find that (in 2015) the

first Sunday in March falls on March 1.

Armed with that information, you can calculate that the second

Sunday falls on March 8. You do this by adding seven (since a

week has seven days).

Since March 8 is a Sunday, it follows that

the 9th, the day following, has to be

a Monday.

If anybody ask you how you are able to put days into dates so

easily, lie a little. Tell them you’ve memorised the entire year’s

calendar.

Good luck!
