Generally 52 weeks are there in a week but one or two days can be extra depending upon the year

The number of weeks in a year depends on the calendar used. In the Gregorian calendar, which is the most widely used calendar in the world, there are 52 weeks and 1 day in a non-leap year, and 52 weeks and 2 days in a leap year.

A leap year is a year that has 366 days instead of the usual 365 days. Leap years occur every four years, except for years that are divisible by 100 but not by 400.

The extra day in a leap year is added to February, which normally has 28 days. In a leap year, February has 29 days.

So, how many weeks are there in a year?

• Non-leap year: There are 52 weeks and 1 day in a non-leap year. This is because 365 / 7 = 52.142857, which means that there is an extra day left over after dividing the number of days in a year by the number of days in a week.
• Leap year: There are 52 weeks and 2 days in a leap year. This is because 366 / 7 = 52.285714, which means that there are two days left over after dividing the number of days in a year by the number of days in a week.

The extra day in a leap year is called February 29th. It is also known as Leap Day.
