A Hebrew birthday is the anniversary of your birth according to the Hebrew calendar, which is a lunisolar calendar used for Jewish religious observances.
It converts your Gregorian birth date to the Hebrew calendar using the Hillel II algorithm, which calculates the molad and applies postponement rules.
In non-leap years, the Hebrew month of Adar II does not exist. If you were born in Adar II, your birthday may not occur in non-leap years.
