Questions
How is a Hebrew birthday worked out?
Your English birth date is converted to the Hebrew calendar date. Each year, your Hebrew birthday is that same Hebrew date, which lands on a different English date.
Why does 'after sunset' matter?
The Hebrew day starts at nightfall. A baby born after sunset has the next day's Hebrew date.
How is the bar or bat mitzvah date calculated?
A boy becomes bar mitzvah on his 13th Hebrew birthday, a girl bat mitzvah on her 12th. The calculator finds that Hebrew date and shows the English date it falls on.
What about Adar in a leap year?
Leap years have Adar I and Adar II. The common custom is Adar II for someone born in a regular year's Adar, but customs vary; the calculator flags it.
Who does the calendar math?
Hebcal, the open Jewish calendar service. This site adds the bar/bat mitzvah date, the parsha, the 20-year list, the calendar file and the shareable card.
