A web tool provided by Chabad.org helps individuals determine their Hebrew birthday and corresponding anniversary of birth on the Hebrew calendar. This often involves converting a Gregorian calendar date (the standard civil calendar) to its Hebrew equivalent. For example, someone born on January 1st might discover their Hebrew birthday falls on the 25th of Tevet.
Determining one’s Hebrew birthday is significant within Jewish tradition. This date is used for observing yearly milestones like a Bar or Bat Mitzvah, and it is the date on which one recites the special Kaddish prayer for deceased parents. Historically, the Hebrew calendar, a lunisolar calendar, has been central to Jewish life, regulating holidays, fast days, and Torah readings. Access to a conversion tool simplifies this process, particularly for those less familiar with the intricacies of the Hebrew calendar system.
