Human beings are governed by the calendar which is full of weeks, generally it has 365 days. Unless it is a leap year that has an extra day, that is, the year lasts 366 days. A year is made up of months, these in turn for weeks and these for days. Generally a month can be between 4 to 5 weeks.

This is because the months have between **30 or 31 days**, except for February which has 27 days and during the leap year it has 28 days. We already know the months and days that a year can have, however, it is important to know how many weeks in a year can have.

The first thing to know is that these **have 7 days**, these are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday. To calculate how many weeks in a year has is very easy, the first thing to do is divide the number of days that the year has by the number of days it has.

That is, 365/7 = 52.1, so a year can have **52 weeks and 1 day**. Not every year can last a full 52 weeks. If the year starts on a Tuesday, it ends on a Thursday and those would not be complete. To say that a year has a certain number of them, it must begin on Monday and end on Sunday.

**For example:**

A year can have 52 weeks and 1 day, minus the leap year.

The year can have only 50 completed, while it meets 52 weeks if the year starts on a Monday.

### How to calculate how many weeks in a year

In order to calculate the number of weeks that a year can have, you will do a very simple mathematical operation. A **365-day year** may have 52 weeks, while a leap year may have 52, but with two more days.

The first thing to consider is whether the month that is about to start is a regular or leap year. So that you do not have to review the entire candlestick, all you have to do is find the month of February. During a leap year the extra day is added to this month; that is, the leap year has 366.

If the year that is about to end is a leap year, the one that will begin is a regular year, this happens because **leap years only occur every 4 years**. The operation that follows is to divide the days of the year with the days of the week, this will provide a figure, generally this figure has several decimal places.

The decimal that must be chosen to complete the figure is the first, the round figure will reveal the number of weeks in the year. While the first decimal will always indicate the days that are missing, since only the weeks that start from Monday to Sunday will be counted.

To have an exact knowledge of the days that will be out of the weeks, especially if the year that is about to start is for half a week. You can also know the number of extra days you will have in the last week of the year. For this, the decimal must be multiplied by 7 and the result will be the number of extra days you have for the year.

The importance of knowing this information

For people who have to plan an event, knowing the weeks that a year has is very useful.

So you can organize your activities; in the same way, people who want to save to buy a product or service. Although it is also useful for children, so they can learn a little more about this information.
