3. # How many days in a year?

Wondering how many days there are in a year? That’s a very good question. To answer this, several criteria must be taken into account:

• Is this a calendar year?
• Is it a leap year?
• Is this a school year?

Do you know the difference between these different types of years? We will help you see it more clearly.

## Number of days in a calendar year

A calendar year is a year beginning on January 1 and ending on December 31. This follows the Gregorian calendar (so called because put in place by Pope Gregory).

In total, a calendar year has 365 days . To be exact, there are 365.2425 days in a calendar year. To make it easier, we tend to round to 365 days. But in order not to distort the count, we add a so-called intercalary day every 4 years and this is what gives us the leap years.

## Number of days in a leap year

During leap years, which occur every 4 years, a day is added to the month of February, which therefore has 29 days instead of 28. Since a classic year has 365 days, a leap year therefore has 366 days thanks to this February 29.

## Number of days in a school year

A school year must include 36 weeks of work. Since public holidays are not counted, this equates to approximately 175 to 180 school days per school year.

4. What is a year of 365 days called?

The Gregorian year refers to the conventional tropical year according to Christopher Clavius ​​(1537–1612) which is exactly 365.2425 days, or 365 days + 1/4 -1/100 +1/400.

A year, therefore, has approximately 365 days and a quarter because it is based on the revolution of the Earth around the sun. That is to say that the earth accomplishes its trajectory around the sun which is a fixed star while the earth rotates in 365 days and a quarter.

You can choose to calculate over 360 or 365 days. 360 days correspond to 12 months of 30 days. So if you start on a pro rata calculation from 360, there is amortization over 28 days in January and 30 days each month that follows. The pro rata will therefore be 358/360.

How long is a year?

The Calendar Year is 365 days; And the Astronomical Year is 365 days, 5 hours, 49 minutes; 1704 leap year.

Why is there no February 29?

Why does the month of February have 28 days, sometimes 29? In the year 45 BC, Julius Caesar admits that the year has 365.25 days and establishes the 12 unequal months including that of February with its 29 days in leap years.

5. With the day counter you can calculate the number of days between two dates, i. H. count the days between the entered start date and end date.

The day calculator first calculates the period between the two dates in years, months, weeks and days. The entire time span is then converted into days and weeks.
