Jewish Calendar Calculator

Keeping track of Jewish dates and holidays can be challenging, especially since the Jewish calendar differs significantly from the Gregorian calendar. Our Jewish Calendar Calculator simplifies this process by instantly converting Gregorian dates to their corresponding Jewish dates, helping you plan for Shabbat, holidays, and other important events.

This tool is designed for anyone—whether you’re planning religious observances, preparing for Jewish holidays, or just curious about the Jewish calendar. It provides accurate information about the Jewish date, day of the week, and event type.


What is a Jewish Calendar Calculator?

A Jewish Calendar Calculator is an online tool that allows you to convert standard Gregorian calendar dates into the Jewish (Hebrew) calendar. The Jewish calendar is a lunisolar calendar, which means it is based on both the moon’s phases and the solar year. Because of this, Jewish dates do not align exactly with Gregorian dates every year, making manual conversion complicated.

Using a Jewish calendar calculator, you can:

  • Determine the Jewish date for any given Gregorian date.
  • Identify the day of the week for that date.
  • Find upcoming Jewish events like Shabbat, Passover, Rosh Hashana, and Yom Kippur.

This tool makes scheduling, planning, and learning about Jewish traditions much easier.
