A Hebrew birthday calculator translates a standard Gregorian calendar birthdate into its equivalent Hebrew lunisolar date (day, month like Nisan or Tishrei, and year Anno Mundi). The Hebrew calendar determines Jewish religious observance dates, yahrzeits, and Bar/Bat Mitzvah milestones.
Y_{\text{AM}} = Y_{\text{Gregorian}} + 3760 \quad (\text{after Tishrei 1})Synchronizes 19-year Metonic cycles where 7 leap years add a 13th intercalary month (Adar II) to align lunar months with solar agricultural seasons.
Scenario: A person born on September 29, 2000.
Gregorian date: September 29, 2000.
Jewish New Year (Rosh Hashanah) occurred on September 30 in 2000.
Date falls on 29 Elul 5760 (Erev Rosh Hashanah).
The Hebrew calendar is lunisolar (months based on the Moon, years adjusted for the Sun), causing Hebrew dates to shift by 10 to 20 days relative to the solar Gregorian calendar.
AM stands for Anno Mundi ("Year of the World" in Latin), counting years from the traditional biblical creation date in 3761 BCE.
During Hebrew leap years, a 13th month is added: Adar I and Adar II. Those born in Adar celebrate in Adar II during leap years.
Yes, Hebrew calendar days officially begin and end at sunset (dusk) rather than midnight.
Calculate exact age in years, months, and days, countdown to next birthday, generation name, and total days lived.
Convert any calendar date into Roman numerals for tattoos, wedding engravings, rings, and monuments.
Find out what day of the week any past or future date falls on, with day-of-year numbers and historical facts.
The Hebrew calendar synchronizes lunar months with solar years. A person's Hebrew birthday is celebrated on the anniversary of the Jewish calendar date on which they were born.
