The Islamic calendar, also known as the Hijri calendar, begins with the year of the Hijra, which marks the migration of the Prophet Muhammad from Mecca to Medina in 622 CE.

A leap year is a year that is one day longer than the normal year. We have them because in reality it takes the Earth one year and 1/4 day to go around the Sun.

If you look real close there are even finer adjustments made every now and then, with leap hours, minutes and seconds. All done to keep the calendar in synch with the seasons.
