- It takes approximately 365.25 days for Earth to orbit the Sun — a solar year. We usually round the days in a calendar year to 365. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.

We have leap years because astronomical events do not repeat in a whole number of days. Earth completes an orbit around the Sun in 365.2422 days. So, a year is 365.2422 days long, not 365 days. It is called a tropical year (or a solar year). It is the time that the Sun takes to return to the same position in the cycle of seasonsas seen from Earth. ...

If the year can be evenly divided by 100, it is NOT a leap year, unless; 3. The year is also evenly divisible by 400. Then it is a leap year. According to these rules, the years 1600, 2000.. etc were, a...

The Gregorian Calendar is named after Pope Gregory XIII (7 January 1502 – 10 April 1585) who introduced it in October 1582. It was developed as a correction to the Julian calendar (proposed by Julius Caesar in 46 BC), shortening the average year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.
