## How Many Days are there in a Year?

Although year calculation is different according to many calendars, it is better to check it with the **gregorian calendar**. *One astronomical year lasts about 365.25 days***.** We accept one year as 365 days however we include the remaining **6 hours to February once in every 4 years**. In this case, there is intercalary year once in *every 4 years*. This intercalary year is because we do not include the remaining 6 hours to the calendar every year. 6 x 4 is equal to 24 hours. This will be included in February once in every 4 years and this is why February lasts 29 days every 4 years.
