Odd days

Odd days is the remainder on dividing a period of days by 7, the unit of a week.

For example, for the month of July having 31 days in any year, Odd days of July = 3.

Similarly for every month except February and every year except a leap year, number of odd days is FIXED and predetermined.

Using odd days, you can solve calendar math problems with ease.

For example, when it is given that 1st October 2012 is Monday, you can easily find the day of 21st December 2013 as a Saturday.
