(1) Take the last two digits of the year and add a quarter again.
(2) Next add to this total the code value for the MONTH.
(3) To this add the day of the month.
(4) Divide the total by seven.
(5) The remainder tells you the DAY according to the day code number. Further Examples:
Date given: April4th, 1931. Equals 31 plus 7 (one quarter) plus 2 (for
April) plus 4, equals 44. Divided by 7 gives a remainder of 2. Less 2 for the twentieth century date given, leaves us with 0 which indicates a SATURDAY.
Date given .January %th, 1900. Equals 8 plus 3 total 11. This minus 2 gives
9 which divided by 7 leaves a remainder of 2 which indicates a MONDAY.
Date given: August 5th, 1752. Last two digits of the year are 52. Divided by 4 gives us 13, which added to 52 equals 65. To this we add the code value for the month (August is 5) and we add another 2 for an eighteenth century date so:— -65 plus 5 plus 2 equals:—72. To this we add the day of the month which is "the fifth" so:—72 plus 5 equals 77. We then divide by 7 which goes exactly so we have 4i0" for the remainder and £*0" from the day code represents a SATURDAY.
