About Hebrew Birthdays

Hebrew birthdays are calculated according to the Jewish calendar, which is a lunisolar calendar. Unlike the Gregorian calendar, Hebrew months begin with the new moon. Your Hebrew birthday occurs on the same Hebrew date each year, which may correspond to different Gregorian dates each year.

• In leap years, there are two months of Adar (Adar I and Adar II)
• Those born in Adar during a common year celebrate in Adar II during leap years
• Significant birthdays: Bar Mitzvah (13), Bat Mitzvah (12), and 80th birthday

The Hebrew calendar is used for Jewish religious observances and includes leap years with an extra month (Adar I). A Hebrew birthday is significant in Jewish tradition, especially for Bar and Bat Mitzvahs at age 12/13.

This calculator converts your Gregorian birth date to the corresponding Hebrew date and calculates when your next Hebrew birthday will occur according to the Jewish calendar.
