Hebrew date
Your Hebrew anniversary, next 10 years
Convert your wedding date to the Hebrew calendar
The Hebrew date on your ketubah is more than a formality. It is the date your community will use to mark your anniversary, and it moves against the Gregorian calendar each year. This free converter turns any wedding date into its Hebrew equivalent instantly, entirely in your browser, and then lists the Gregorian date of your Hebrew anniversary for the next ten years.
The Hebrew calendar is lunisolar: months follow the moon, but leap months keep the year aligned to the seasons. That is why a wedding on, say, the 15th of Sivan will fall on a slightly different Gregorian date every year. Knowing both dates helps you plan anniversaries, order a milestone gift, or simply understand what your ketubah says.
Our calculation uses the standard algorithm for the fixed Hebrew calendar, the same arithmetic used to set the Jewish holidays, so the results match what your rabbi and your ketubah will use. If your wedding is close to sunset, remember that the Hebrew date changes in the evening, not at midnight; for a ceremony held after nightfall, use the following civil day.
Once you have your date, you might enjoy our text generator, which folds the Hebrew date straight into a sample ketubah text, or our signing ceremony guide.
Common questions
Why does my Hebrew anniversary fall on a different day each year?
The Hebrew calendar is lunisolar, so Hebrew dates drift against the Gregorian calendar and shift by a couple of weeks from year to year. The converter shows you the exact Gregorian date for each of the next ten years.
Does the Hebrew date change at sunset?
Yes. The Jewish day begins at nightfall. If your ceremony is held after dark, the Hebrew date is that of the following civil day. For daytime weddings the civil date is correct.
Is the converter accurate?
It uses the standard fixed-calendar arithmetic, validated against known dates, so it matches the dates used for Jewish holidays and documents.
