1. Write down your date of birth using 6 figures. So 25th December 1974 would be 25.12.74
2. Write down the last two digits of the year. (eg 74)
3. Divide by 4 and ignore the decimal part or remainder. (eg 74 ÷ 4 = 18)
4. Add together the answers to 1 and 2 (eg 74 + 18 =92)
5. Add the number of the day of your date of birth. (eg 92 + 25 =117)
6. Add a number according to your month of birth as follows.
JAN 1 (0 for Leap Year) How do you tell if a year is a leap year?
FEB 4 (3 for Leap Year) How do you tell if a year is a leap year?
MARCH 4
APRIL 0
MAY 2
JUNE 5
JULY 0
AUGUST 3
SEPT 6
OCT 1
NOV 4
DEC 6
(eg 117 + 6 for Dec = 123)
For years beginning 18.. add 2
For years beginning 19.. add 0
For years beginning 20.. add 6
(eg 123 +0 = 123)
Divide your answer by 7 and work out the remainder.
(eg 123÷ 7 = 17 remainder 4)
The remainder gives the day of the week you were born on.
1 = Sunday
2= Monday
3= Tuesday
4= Wednesday
5= Thursday
6 = Friday
7 = Saturday
