Passover Date Calculator

Passover (Pesach) begins on 15 Nisan in the Hebrew calendar — the first seder night. On the Gregorian calendar that date moves each year because the Hebrew year is lunisolar: months follow the moon while leap months keep festivals aligned with seasons over a 19-year cycle.

In Israel many communities observe seven days of Passover; in the Diaspora many observe eight. Select the observance length that matches your practice. The calculator shows the Gregorian date of 15 Nisan and counts festival days through the last day of observance you choose.

With the defaults — Diaspora (8 days) and Gregorian year 2026 — Passover starts 2026-04-02 (15 Nisan), ends 2026-04-09, and falls in Hebrew year 5786. The eight-day window includes two seders at the start for many Diaspora customs.

Jewish days begin at sunset, not midnight. The Gregorian date shown is the civil calendar day associated with 15 Nisan — candle lighting and the first seder are the prior evening. Confirm exact times with your community calendar or a city-specific zmanim table.

Why seven days in Israel and eight in the Diaspora? Historical calendar communication led to an extra day of Yom Tov in many Diaspora communities as a safeguard. Modern practice still differs — pick the toggle that matches your synagogue and family tradition.

Pair with the live days-until-Passover countdown when you want a rolling view from today rather than a fixed civil year. The Rosh Hashanah calculator covers 1 Tishrei — the other major spring/fall anchor on the Hebrew calendar.

Results follow standard Hebrew-calendar algorithms (Hebcal-style). Community calendars may match exactly on the civil date while differing on candle-lighting minutes. This is a planning estimate, not halachic guidance.
