Hebrew Birthday Calculator

In Jewish tradition, your Hebrew birthday is spiritually significant. It's considered an auspicious time for prayer, reflection, and personal growth. Many believe it's a day when your spiritual energy is renewed, and some have the custom to study the Torah portion of their birth week annually.

At age 13, Jewish boys become Bar Mitzvah ("son of the commandment"), meaning they take on adult religious responsibilities. For girls, this transition happens at age 12 (Bat Mitzvah). These ages are always calculated according to the Hebrew calendar, not the Gregorian calendar.

The Hebrew calendar is lunisolar, based on both the moon's cycles and the solar year, while the Gregorian is purely solar. Hebrew months have 29 or 30 days, and leap years have an extra month (Adar II) to synchronize with seasons. This results in Hebrew dates shifting each year relative to Gregorian dates.

This tradition comes from Genesis: "And there was evening, and there was morning—the first day." Jewish days begin at nightfall (when at least three stars are visible). This affects birth dates - a baby born after sunset has the next day's Hebrew date.

This refers to the weekly Torah portion (Parashat HaShavua) that was read on the Shabbat during the week of your birth. Some believe this portion carries special meaning for your life journey. Our calculator identifies your unique Torah portion based on your Hebrew birth date.

Our calculator follows traditional Jewish calendrical rules. For dates after 1582 (when the Gregorian calendar was adopted), it's extremely accurate. For dates before 1582, it uses the Julian calendar conversion.

Yes! Simply enter your child's birth date, and we'll show their Hebrew birth date. Add 12 years for girls or 13 years for boys to determine their Hebrew coming-of-age date. The Bar/Bat Mitzvah is typically celebrated on the Shabbat following their Hebrew birthday.

The Hebrew calendar adds a leap month (Adar II) 7 times every 19 years. If you were born during a leap year, your birthday is celebrated in Adar II. If you were born in Adar during a regular year, there's debate whether to observe it in Adar I or Adar II during leap years.

Hebrew birthday celebrations often include religious elements like giving extra charity, studying Torah, and reflecting on personal growth. Some have the custom to be called to the Torah on the Shabbat following their birthday. Traditional foods might include round challah symbolizing the cycle of life.
