when is your birthday if born on leap year
February 29 A person born on February 29 may be called a "leapling", a "leaper", or a "leap-year baby".[6] In non-leap years, some leaplings celebrate their birthday on either February 28 or March 1, while others only observe birthdays on the authentic intercalary date, February 29.
Hebrew calendar The Jewish calendar is based on the Metonic cycle of 19 years, of which 12 are common (non-leap) years of 12 months and 7 are leap years of 13 months. To determine whether a Jewish year is a leap year, one must find its position in the 19-year Metonic cycle. This position is calculated by dividing the Jewish year number by 19 and finding the remainder. For example, the Jewish year 5778 divided by 19 results in a remainder of 2, indicating that it is year 2 of the Metonic cycle. Since there is no year 0, a remainder of 0 indicates that the year is year 19 of the cycle.[43]
