Hebrew Date Converter

Convert dates and find holidays, birthdays, and yahrzeits

Convert a Gregorian date to a Hebrew date, including Israeli holidays and festivals. Pick a date to get the Hebrew day, month, and year in letters, alongside the full Gregorian date. The tool also shows the Gregorian date when that same Hebrew date will fall next year. This is exactly what you need for a Hebrew birthday, a bar mitzvah, or a yahrzeit (memorial anniversary). Keep in mind that the Hebrew day begins at sunset, so an evening event belongs to the next day's Hebrew date.

Frequently asked questions

Is the conversion accurate?

Yes. The calculation uses Hebcal, the standard library for Hebrew calendar calculations. It correctly handles leap years and the two months of Adar.

Why is my Hebrew date off by one day?

The Hebrew day begins at sunset. Anyone born in the evening belongs to the Hebrew date of the following day. This is the most common reason for a gap between family memory and the calculated date.

How do I determine a yahrzeit?

Enter the Gregorian date of passing to get the Hebrew date, which repeats every year, along with the Gregorian date it falls on next year. If the passing occurred after sunset, enter the Gregorian date of the next day.

Can I enter a Hebrew date to get a Gregorian one?

Not directly. The tool takes a Gregorian date and returns a Hebrew one, and also shows when that Hebrew date will fall next year on the Gregorian calendar. This helps you find an upcoming Hebrew birthday or memorial.

What happens with a date in Adar during a leap year?

A leap year has two months of Adar. A date set in Adar during a regular year is usually observed in Adar II. However, customs vary, and it is common to consult a rabbi before setting a memorial date.
