A Leap Year is also called an intercalary year or bissextile year. It is any year that is divisible by four.
Leap Day is February 29th. Leap Day falls on the same day as February 1.
This year the first of February is on a Saturday. Leap Day in 2020 is the last Saturday of the month. An extra day is added to February every four years because having only 28 days, February is the shortest month of the Gregorian Calendar.
Every four years the Earth orbits the sun in a little less time. What happens to those extra minutes? They become Leap Days. Without an extra day, every four years our seasons would begin a day earlier. Julius Ceasar introduced a Leap Year to the Gregorian Calendar.
In a leap year, the months of January, April, and July all start on the same day of the week.
Countries that use a lunar calendar rather than a solar calendar add a leap month every four years.
Leap seconds are added when needed to keep the clocks synchronized with the slowing rotation of the Earth. The last leap second was added on December 31, 2016. There have been 26 leap seconds added since 1972.
Have a great February. Use your time wisely
