Gregorian to Hebrew Date Converter

Enter a date in the Gregorian calendar and the tool returns the equivalent date in the Hebrew calendar using the standard relationship between the two systems.

1. 1

   Step 1

   Enter the complete Gregorian date — day, month, and year.

2. 2

   Step 2

   We apply both systems' rules: a Gregorian year runs about 365 days against the Hebrew 365 (≈0 days apart each year).

3. 3

   Step 3

   The result shows the correct Hebrew day, with Hebrew leap years applied date by date.

• 1

  Gregorian and Hebrew dates do not map one-to-one — the two systems start from different epochs and count leap years differently, so enter the full Gregorian date and read the Hebrew equivalent instead of shifting the year by a fixed offset.

• 2

  Enter the Gregorian–Hebrew dates in YYYY-MM-DD format to avoid ambiguity — some conventions read 03/04 as March fourth and others as April third, and a swapped month and day silently shifts every result this page derives.

• 3

  Leap rules differ between the calendars behind Gregorian–Hebrew, so a span that looks like whole years in one system can land a day or two off in another; trust the converted result rather than a fixed mental offset.

• Anniversaries do not survive conversion unchanged: a Gregorian date maps to a fixed Hebrew date, but next year's Gregorian anniversary lands on a different Hebrew date. Reconvert each occurrence instead of adding one year to the last result.

• Reversing the direction is a silent trap: converting from the Hebrew calendar back to the Gregorian calendar needs the inverse relation, and off-by-one errors cluster at month boundaries where the systems disagree. Verify the round trip returns your original date.
