In a normal year, when 365 is divided by 7 (no of days in a week) we get a remainder of 1 and a quotient of 52. That means there are 52 weeks in a normal year and the remainder 1 signifies the one extra day in a normal year which is an odd day. Hence a normal year would have 52 weeks and 1 odd day.

In the case of a leap year, when 366 is divided by 7, we get a remainder of 2 and a quotient of 52. That means a leap year which comes in every 4 years would have 52 weeks and 2 odd days.

Now consider the months in a year. There are 12 months in a year starting with January and ending with December. February is the only month that has different days depending on a normal year or a leap year. In a normal year, February has 28 days but in a leap year, there are 29 days in February.
