Every fourth year
The Julian calendar—since 1923, a liturgical calendar—has a February 29 every fourth year without exception. (Consequently, February 29 in the Julian calendar falls 13 days later than February 29 in the Gregorian calendar, until the year 2100.)
A leap year takes place roughly every four years, when an extra day is added to the Gregorian calendar, making the total duration of that year 366, not 365, days. The extra day is added at the end of the month of February. Feb. 29 is known as leap day.
When is the next leap year and day? The next leap year will be in 2024, which means the next leap day will be February 29, 2024.
If we take the example of the year 2024, the number 2024 is both divisible by 4 (2024/4=506) and not divisible by 100 (2024/100=20,24). So 2024 will be a leap year and it was the same for the last leap year which took place on February 29th 2020.
Every four years, an additional day is added to the month of February, which makes 29 February is a Leap Year. However, 2023 is not a Leap Year, as this year February ends on Tuesday 28. The Gregorian calendar usually has 365 days, but in a Leap Year, it has 366 days.
The next leap day is February, 29, 2024.
The least common birthday is leap day, or February 29. But because the day only occurs once every four years, it’s obvious it would yield the least amount of birthdays. The rarest birthday of the 365 annual calendar days is Christmas Day, Dec. 25.
In non-leap years, that day is March 1. So for someone born on February 29, the first day they can legally drive, vote, join the Army, buy alcohol or start collecting Social Security is presumably March 1 in non-leap years.
