Understanding Your Hebrew Birthday
Your Hebrew birthday is the date on the Jewish (Hebrew) calendar corresponding to the day you were born. Because the Hebrew calendar is lunisolar — following both the moon and the sun — your Hebrew birthday falls on a different Gregorian date each year. This is why a Hebrew birthday converter is essential for anyone who wants to celebrate or commemorate this meaningful day.
In Jewish tradition, a person's birthday is considered a day of special spiritual power. The Talmud (Yerushalmi, Rosh Hashanah 3:8) discusses the significance of birthdays, and many great rabbis throughout history have emphasized the importance of marking one's Hebrew birthday. It is customary to give extra charity (tzedakah), study additional Torah, and recite Psalms on this day.
The Hebrew calendar has 12 months in a regular year and 13 in a leap year (which occurs 7 times in every 19-year cycle). Each month begins with the new moon (Rosh Chodesh) and has either 29 or 30 days. The months, starting from Nisan (the month of Passover), are: Nisan, Iyyar, Sivan, Tammuz, Av, Elul, Tishrei, Cheshvan, Kislev, Tevet, Shevat, and Adar. In a leap year, Adar II is added.
Understanding your Hebrew birthday is especially important for lifecycle events like a Bar Mitzvah (age 13 for boys) or Bat Mitzvah (age 12 for girls), which are celebrated on the Hebrew birthday. It is also the date used for yahrtzeit (memorial anniversary) observance.
Frequently Asked Questions
How do I find my Hebrew birthday?
Simply enter your Gregorian (English) date of birth into the converter at the top of this page. It will instantly calculate your Hebrew birthday, show you the Hebrew date, and tell you when your next Hebrew birthday falls on the Gregorian calendar.
Why is my Hebrew birthday on a different date each year?
The Hebrew calendar is lunisolar — its months follow the lunar cycle (~29.5 days each), while leap years add an extra month to stay aligned with the seasons. Because the Hebrew year is about 11 days shorter than the Gregorian year (before leap year adjustments), your Hebrew birthday shifts on the English calendar each year.
What is the significance of a Hebrew birthday?
In Jewish tradition, your Hebrew birthday is considered a day of special spiritual energy. Many customs are associated with it: giving charity, studying Torah, reciting Psalms, and holding a celebration (seudah). The Lubavitcher Rebbe taught that each person's Hebrew birthday is a personal "Rosh Hashanah" — a day to reflect on the past year and set intentions for the year ahead.
When does my Hebrew birthday start?
The Hebrew day begins at sunset, not midnight. So your Hebrew birthday celebration actually begins at sunset on the evening before the corresponding Gregorian date. For instance, if your Hebrew birthday converts to Wednesday on the Gregorian calendar, it begins at sunset on Tuesday evening.
How do I calculate a Bar Mitzvah or Bat Mitzvah date?
A Bar Mitzvah occurs on a boy's 13th Hebrew birthday, and a Bat Mitzvah on a girl's 12th Hebrew birthday. First, use this converter to find the child's Hebrew birthday, then count forward 13 (or 12) Hebrew years. Because the Hebrew calendar has variable year lengths, the calculation requires Hebrew calendar rules — it won't simply be the same Gregorian date 12 or 13 years later.
What if I was born in Adar during a non-leap year?
If you were born in Adar during a regular (non-leap) year, your Hebrew birthday is celebrated in Adar in non-leap years and in Adar II in leap years. If you were born in Adar I of a leap year, your birthday is celebrated in Adar I in leap years and in Adar in non-leap years. Opinions vary for those born in Adar II — consult your rabbi for guidance.
