5. Date Calculation
Last but not list translate your answer,
into number which will be a 0-6 and
0 represent Saturday 1 represent Sunday
and so on.

6. Century Formula
 C.F. = Century divide by 4. ex 20/4 remi = 0 = 6 or (-1)
 If reminder
 0 = 6(-1)
 1= 4
 2= 2
 3= 0
.

7. Year Formula
 If year = 70
 Year Code. = Year /4 = (17) quotient +
year / 7 (0) Reminder
Again, quotient + reminder 7 = 17+0=7 = 3
(Reminder) so
Day = Tuesday
Note: Quotient + Reminder / 7 and count the
reminder as a day

8. Months Formula
 Tricks 144….. 146 in in
between square of 5 and 6
before it place 0 on it.
 January = 1
 February = 4
 March = 4
 April = 0
 May = 2
 June = 5
 July = 0
 August = 3
 September = 6
 October = 1
 November = 4
 December = 6
Note: If there is Jan or
Feb Month code value
should be decrease by
one in leap year.

9. Calendar Memorizing
 Example1:
2023 march 23
c/4 = 20/4 reminder 0 = 6 (-1)
Year = 23 = 0
Month = March = 4 Day = 23
 Example1:
2320 November 30
c/4 = 23/4 reminder 3 = 0
Year = 20 = 4
Month = Nov= 4
Day = 30
6+ 0 + 4 + 23 = 33/7= 5( Thursday)
0 + 4 + 4 + 30 = 38/7= 3( Tuesday)
