15 Nisan
Passover Date
Civil first night of Passover from the Hebrew calendar.
Passover date
Enter a Gregorian year. Sighting calendars may differ by a day.
Passover Date reports the Gregorian civil date of 15 Nisan, the first day of Passover, for a Gregorian year you enter. The conversion uses the fixed arithmetic Hebrew calendar (the civil calendar used in software tables), not a local moon sighting and not a rabbinic ruling. Make a Calendar publishes the civil mapping so planners can circle a date; it is not liturgical authority. Communities may begin the seder at sundown the evening before that civil date.
Fifteen Nisan, not a full festival calendar
Passover (Pesach) begins on 15 Nisan. In Israel the biblical festival is seven days; in much of the diaspora many communities keep eight. This page prints the civil first day, not every Chol HaMoed date, not the last day, and not Shavuot seven weeks later. If you need an arbitrary Hebrew Y-M-D translated both ways, use the Hebrew date converter instead of this feast-specific lookup.
Nisan is a spring month in the lunisolar Hebrew calendar. Leap years insert Adar II so that 15 Nisan stays in spring relative to the solar year. The arithmetic rules (including Rosh Hashanah postponements) are why 15 Nisan is not a fixed Gregorian month-day. It moves, mostly in March and April on the civil calendar.
The result line includes the Hebrew year label the engine used for 15 Nisan alongside the long Gregorian date. Read both. A school newsletter that prints only “April” without 15 Nisan will confuse families who plan by the Hebrew date on a wall calendar.
Seder evening versus civil midnight
Hebrew days begin at sundown. The first seder is held after nightfall at the start of 15 Nisan, which is the evening of the previous Gregorian date for most clock-facing planning. If the tool prints a Tuesday civil date for 15 Nisan, the first seder is Monday after dark in ordinary temperate latitudes, with exact nightfall depending on location. This page does not compute tzeit or candle-lighting minutes.
Workplace leave is often requested for the civil dates of the first (and, in the diaspora, second) days. Those leave dates are not the same as “the evening before.” Spell out whether a request covers the seder night, the daytime festival, or both. A civil first-day printout is a starting point for that conversation, not a completed HR form.
Public-school testing calendars in some US districts avoid the first days of Passover. Administrators should still confirm with community calendars, because a one-day civil slip from a congregation that waits for confirmation will not be reflected here.
Arithmetic calendar versus local practice
The fixed Hebrew calendar has been used for centuries for civil and most communal scheduling. It is still not a substitute for a rabbi, a vaad, or an Israeli Chief Rabbinate announcement when a community treats those as binding. Some groups historically waited on sighting; almost all Jewish communities today use the calculated calendar for 15 Nisan, but you should not cite this webpage in a halachic dispute.
Karaite and some other calendars can differ. If a reader follows a calendar that is not the Rabbinic calculated calendar, this Gregorian date may be wrong for them by a day or more. Label the output as civil 15 Nisan (calculated) when you paste it into a interfaith office memo.
Christian Easter is related historically to Passover but is not the same computation. Western Easter and Orthodox Pascha have their own pages. Do not assume 15 Nisan is “the Sunday before Easter” or any other Christian rule. The Orthodox Easter date is a separate ecclesiastical computus.
Worked lookups
Enter 2026 and read 15 Nisan’s Gregorian date and the day-count from today. If the date is in the past for this year, you are looking at the spring that already occurred; enter the next year for the upcoming festival. The day-count is civil midnights, not “nights remaining until the seder.”
A campus chaplain planning kosher-for-Passover dining needs the first-day date plus the local custom on eight versus seven days. This page supplies only the first civil day. Kitchen staff still need procurement lead time measured in calendar days before that date; use ordinary date math for lead time, not the Hebrew converter, unless labels on boxes are in Hebrew months.
Genealogists who only have “Pesach 1945” still need a year-specific conversion. Enter 1945 (a nineteenth-century-or-later civil year the form accepts) and record both 15 Nisan and the Gregorian date in the notes so later readers can search either calendar.
Planning beside other calendars
US federal holidays do not include Passover. Some states and cities publish school guidance. See holidays 2026 for federal civil dates that may sit near Nisan, such as spring observances, without treating them as substitutes for 15 Nisan.
Circle the date on a monthly calendar or a yearly calendar 2026 after you trust the conversion. Leap years affect weekday alignment of the civil date, not the Hebrew month-day 15 Nisan itself.
Ramadan, Easter, and Passover can fall near each other in some years and far apart in others. Each feast has its own engine. Do not reuse a Passover Gregorian date as a proxy for another tradition’s fast or feast.

Frequently asked questions
What Hebrew date is the first civil day of Passover?
Passover begins on 15 Nisan. This page maps that Hebrew date to a Gregorian civil date for the year you enter, using the fixed arithmetic Hebrew calendar. It does not list every festival day, the last day, or Shavuot. Use the Hebrew date converter when you need other month-day values besides 15 Nisan.
How is 15 Nisan converted into a Gregorian calendar date?
The engine uses civil Hebrew calendar arithmetic, including leap-month placement so Nisan stays in spring, then converts 15 Nisan to a Gregorian Y-M-D. The printed line includes the Hebrew year label and the long civil date. The mapping is for planners, not a ruling in a halachic dispute.
Why might a congregation posted date differ by one day?
Most communities use the calculated calendar, but a group that follows a different tradition, a delayed confirmation, or a publication that cites seder night as the civil date can disagree by a day. Time zones and sundown also shift which civil date a poster emphasizes. Treat this page as civil 15 Nisan, calculated, and confirm locally when it matters.
Is this page a substitute for a rabbinic liturgical calendar?
No. It is a civil conversion of 15 Nisan for scheduling. It is not a teshuva, a Chief Rabbinate notice, or candle-lighting times. Do not cite it as liturgical authority. Campus, HR, and interfaith memos should label the source as a calculated civil date and defer to the community for observance details.
When does the first seder evening actually begin relative to 15 Nisan?
Hebrew days start at sundown, so the first seder is after nightfall at the beginning of 15 Nisan, which is the previous Gregorian evening for ordinary planning. This page does not compute nightfall minutes. If 15 Nisan is a Tuesday civil date, the seder is Monday night in typical temperate locations, with local sunset varying.
How do I look up other Hebrew dates besides Passover itself?
Open the Hebrew date converter for two-way translation of any Hebrew Y-M-D, including Adar II in leap years. This Passover page is deliberately narrow: one feast, one year field, one first-day civil date. Mixing a full converter with a feast lookup keeps each URL’s job clear for bookmarks and search.
