You may want to memorize some rules to master this trick, but they are quite easy to keep in mind.
Initially, we assign a code number to every day of the week.
Monday – 1
Tuesday – 2
Wednesday – 3
Thursday – 4
Friday – 5
Saturday – 6
Sunday – 7 or 0
2nd, we assign a code number for each month of the year. These month rules are used for on a yearly basis with two exceptions. In a leap year, the month rule for January is 5 as well as February is 1. The month codes aided by the corresponding mnemonics are the following:
January – 6 (COLD WEATHER features 6 letters)
February – 2 (second month)
March – 2 (You march with 2 foot)
April – 5 (APRIL features 5 letters)
May – 0 (MAY0 for mayonnaise)
Summer – 3 (JUN features 3 letters)
July – 5 (JULIE features 5 letters)
August – 1 (August starts with A The, the first page)
September – 4 (SEPT features 4 letters)
October – 6 (Halloween TIPS or SNACKS have actually 6 letters each)
November – 2 (2nd final month)
December – 4 (XMAS features 4 letters)
3rd, we assign a code number for each year. As an example, the entire year rule for 2011 is 6.
The Formula
Day’s the week = (period rule + Date + 12 months Code) mod 7
Note: mod 7 shows the remainder you obtain when you divide by 7.
Instances
What’s the time for July 16, 2011?
Day’s the week = (period rule + Date + 12 months Code) mod 7
Day’s the week = (5 + 16 + 6) mod 7 = 27 mod 7 = 6 (for that reason, it’s a Saturday)
What’s the time for December 25, 2011?
Day’s the week = (period rule + Date + 12 months Code) mod 7
Day’s the week = (4 + 25 + 6) mod 7 = 35 mod 7 = 0 (for that reason, it’s a Sunday)
Hooray! With constant rehearse, you’re today prepared be the walking diary. Amaze friends, peers, pupils, teachers and everybody else.
