What are Odd Days:
By odd days, we mean the number of days left after complete number of weeks.

Let's calculate the number of Odd Days in 1 year.
1 Year = 365 Days
Odd Days = 365 mod 7 = 1
It means 1 Day (the last day) is in incomplete week or leftover

In case of Leap Year
1 Year = 366 Days
Odd Days = 366 Mod 7 = 2
It means 2 Days (the last and second last day) are in incomplete week or leftover.
