How to find the ‘day’ when you know the date, month, and year.

Steps to solve a question with example:

What was the day on ’11-06-1996’ ?

1.       Add the digits of the date to the last two digits of the year.	11 + 96 = 107
2.       Divide the last two digit of the year by 4.	96/4 = 24
3.       Now, add the quotient value obtained from step 2 to the result obtained from step 1.	107 + 24 = 131
4.       Add month and year code to result obtained from step 3.	131 + 4 (month code) + 0 (year code) = 135
5.       Divide the result obtained from step 4 by 7.	135/7 Quotient – 10. 3 Reminder – 02
6.       Match the reminder obtained from step 5 to the day code.	Reminder obtained – 02 So, the day was a Tuesday.
