Leapling – Are People Born On The 29th February During A Leap Year…
February 29 comes only every 4th year according to the Gregorian Calendar.
February 29 is a date that occurs only every four years, in years evenly divisible by 4, such as 1988, 1996, 2008 or 2016 (with the exception of century years not divisible by 400, such as 1900). The year you were born in are called leap years, and February 29 is the 60th day of the Gregorian calendar in such a year, with 306 days remaining until the end of that year. February 29 is also known as bissextile day.

A leap year (or intercalary year) is a year containing one or more extra days (or, in case of lunisolar calendars, an extra month) in order to keep the calendar year synchronised with the astronomical or seasonal year. For example, February would have 29 days in a leap year instead of the usual 28. Seasons and astronomical events do not repeat at an exact number of full days, so a calendar which had the same number of days in each year would over time drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected. A year which is not a leap year is called a common year.

The Gregorian calendar, the current standard calendar in most of the world, adds a 29th day to February in 97 years out of every 400, a closer approximation than once every four years. This is implemented by making every year divisible by 4 a leap year unless that year is divisible by 100. If it is divisible by 100 it can only be a leap year if that year is also divisible by 400.
