How does a Hebrew birthday work?

The Jewish day starts at sunset, so a baby born after sunset has the next Hebrew date. A Hebrew birthday falls on a different English date each year. A boy becomes bar mitzvah on his 13th Hebrew birthday; a girl becomes bat mitzvah on her 12th. Someone born in Adar of a regular year celebrates in Adar II in a leap year (13 months); someone born in Adar I or Adar II keeps that month in a leap year, and Adar in a regular year.
