The Leap Year

Although most years of the modern calendar have 365 days, a complete revolution around the sun takes approximately 365 days and 6 hours. Every four years, during which an extra 24 hours have accumulated, one extra day is added to keep the count coordinated with the sun's apparent position. That is why we have February 29 every 4 years. The leap year was introduced as part of the Julian calendar reform. February 29 came to be regarded as the leap day when the Roman system of numbering days was replaced by sequential numbering in the late Middle Ages.
Some important events that took place on February 29 in leap years:
