It Pays to Remember Dates 107
called, you almost immediately tell them the day of the
week for that particular date!
To accomplish this you must know two things besides
the month, day and year: a certain number for the year,
which I will refer to as the "year key," and a certain num-
ber for the month, which I'll call the "month key."
Perhaps, if I explained the method and procedure be-
fore going into the technicalities, you would find it easier
to understand. This is it:— Let's assume that you want to
know the day of the week for March 27, 1913. Let's also
assume that you know the "year key" for 1913 is 2, and
that the "month key" for March is 4. You would add these
two keys, arriving at #6. Now you add this number (6) to
the day, in this particular case—#27 (March 27). This
gives you a total of 33. The last step is to remove all the
sevens from your total. Seven goes into 33 four times,
(4X7== 28); remove 28 from 33, which gives you a final
total of 5. That is your day—the fifth day of the week is
Thursday! For this stunt we must consider Sunday as the
first day, Monday the second day; Tuesday the third day;
Wednesday the fourth day; Thursday the fifth day; Friday
the sixth day and Saturday the seventh day.
March 27, 1913 did fall on a Thursday! Please don't con-
sider this complicated; it isn't. Actually you will never have
to add any numbers higher than seven. The keys for the
years and the months are all either 0, 1, 2, 3, 4, 5, or 6.
Sevens are always removed as soon as possible. If you had
to add a "year key" of 5 to a "month key" of 6, you would
arrive at 11; but immediately remove one seven, which
leaves you with 4. The 4 is all you would have to keep work-
ing with. If the day that is given you is higher than seven,
you remove all the sevens, i.e.—the date is the 16th; re-
move the two sevens (2X7= 14) and use the remainder
of 2 only. In the above example, you would simply add 4 to
