Say Thanks to pedagonet

Ask what, day, month and year the person was born.
Then tell them which day of the week this person was born.

How to predict the day :

Example :

Let us assume the person reveals that his date of birth was February 12, 1978.

Two formulas are used for prediction :

January, October = 0
May = 1
August = 2
February, March, November = 3
June = 4
September, December = 5
April, July = 6

Sunday = 0
Monday = 1
Tuesday = 2
Wednesday = 3
Thursday = 4
Friday = 5
Saturday = 6

1 – Drop the “19” in the year of birth (1978 becomes 78)
2- Divide this number by 4 and drop the remainder (78 / 4 = 19 remains 2)
3- Add this answer to year of birth ( 19 + 78 = 97)
4- Add the day of the month of birth to this total (97 + 12 = 109)
5- From the first formula, add the value of the month (February = 3, 109 + 3 = 112)
6- Divide this total by 7 (112 / 7 = 16 remains 0)
7- Take this remainder (0) and apply this number to the days in formula 2) 0 = Sunday

Therefore, he was born on a Sunday.
