# How Many Days Are in a Year? [Answered]

The Gregorian calendar, which is the most common calendar in use today, consists of 365 days. However, every four years there is an extra day added, or leap year, which brings the total number of days up to 366. This occurs because it actually takes the Earth 365.24 days to orbit around the sun. The slight discrepancy is made up by adding an extra day, or leap day, every four years.

There are other ways that a year can be measured as well. The Julian year is named after Julius Caesar, who introduced this system of measurement. In the Julian year, there are 365.25 days in a year. This system of measurement was created because the Earth’s orbit around the sun is actually slightly longer than 365 days. The Sidereal year is another way of measuring a year. In this system, a year is equal to 365.25636 days. This measurement is based on the amount of time it takes for the Earth to rotate around the sun one time. No matter how you measure it, a year always has a defined length of time.
