How Many Days in a Year

 

One year consists of 12 months, and usually lasts 365 sidereal days. A sidereal year is the time when the round takes a complete turn around the sun.

There are different types of year, which have been adopted by various cultures through the ages, among them: The sidereal year, the solar year and the calendar year, which is used for the measurement of religious holidays.

Astronomers discovered after several studies that during a period of every four years 366 days are counted, and this year it is called a leap.

 

Exactly

Every year is exactly 365 days, 5 hours, 48 minutes and 46 seconds. This is why exist normal years and leap years

 

Normal Year

One normal year has 365 days. The year is divided into 12 months, which have 30 or 31 days, except February that has 28.

 

Leap Year

One leap year has 366 and it occurs every four years (see more about why is there a leap day and when is the next leap year) The year is divided into 12 months, which have 30 or 31 days, except February that has 28.

 

Without weekends

If you don’t want to count weekends then the number of days is 261 = 365 – 104 (number of Saturdays and Sundays).
