Leap Day:
Leap day, also known as leap year day, is an extra day added to the month of February in a leap year. February 29th is the 60th day of a leap year in the Gregorian calendar. It occurs every four years in years evenly divisible by four except for centensry years not divisible by 400.
A leap day is more likely to occur on Mondays or Wednesdays rather than other days because the Gregorian calendar repeats itself every 400 years. Therefore Feb. 29 can occur 15 times on a Monday or Wednesday, 14 Times on a Friday or Saturday and 13 times on a Sunday, Tuesday, or Thursday.
Brief History of Leap Day:
In ancient Rome, leap day was on February 24th due to February being the last month of the year. The original Roman calendar added an extra month every few years to maintain the correct seasonal changes. The Julian calendar was implamented in 45 BCE, resulting in a leap day being added to the end of February every four years.
In 1582 Pope Gregory XIII refined the Julian calendar with a new rule that a century year is not a leap year unless it is evenly divisible by 400.
