What was the day of the week on 28th May, 2006?
Thursday
Friday
Saturday
Sunday
Answer: Option
Explanation:

28 May, 2006 = (2005 years + Period from 1.1.2006 to 28.5.2006)

Odd days in 1600 years = 0

Odd days in 400 years = 0

5 years = (4 ordinary years + 1 leap year) = (4 x 1 + 1 x 2) 6 odd days

Jan.  Feb.   March    April    May 
(31 +  28  +  31   +   30   +   28 ) = 148 days

148 days = (21 weeks + 1 day) 1 odd day.

Total number of odd days = (0 + 0 + 6 + 1) = 7 0 odd day.

Given day is Sunday.

In 1 year there are 365days which year is non leap year.

365/7(to calculate number of weeks)

=52 is quotient and 1 is reminder(this is odd day)

This means for a non leap year there are 52 weeks and 1day.

Why odd days for 1600 and 400 are zero? Thank you in advance.

@Ajay.

If you divide 1600 and 400 by 4 then reminder is nothing that's why odd days are zero. If reminder is 1 then odd day=1 and if reminder is 2 then odd days=2 is it ok ?.
