**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.*
