Passover, or Pesach in Hebrew, is one of the most significant and widely observed Jewish holidays, commemorating the liberation of the Israelites from slavery in ancient Egypt. The question "what day is Passover celebrated" does not have a single fixed date, as the holiday is tied to both the Hebrew calendar and the agricultural cycles of the Land of Israel. Understanding its timing requires looking at a specific date within a particular month, which shifts slightly each year on the standard Gregorian calendar used for civil purposes.
Calculating the Date of Passover
On the Hebrew calendar, which is lunisolar, Passover begins on the 15th day of the month of Nisan. This places it squarely in the spring season, aligning with the biblical command to observe the holiday "in the month of spring" (Aviv). Because the Hebrew year is based on lunar cycles, the 15th of Nisan moves back and forth relative to the Gregorian calendar. Consequently, the answer to what day is Passover celebrated lands on a range of dates between March 26 and April 25 over the course of a given year.
Passover in 2024 and 2025
To provide concrete context, the holiday observed in the spring of 2024 began at sundown on April 22 and concluded at nightfall on April 30. Looking ahead to 2025, the dates shift earlier in the Gregorian calendar. In 2025, the holiday commences at sundown on April 12 and finishes at nightfall on April 20. This annual drift is a direct result of the mathematical formula used to ensure the holiday remains tied to the spring harvest, a core element of its historical narrative.
Duration of the Holiday
The specific length of the observance varies based on location and tradition. In Israel and for many Reform Jewish communities, the holiday is celebrated for seven days, with the first and last days being major festivals. In the diaspora, however, an ancient custom dictates an eight-day observance, stemming from the historical challenge of accurately communicating the sighting of the new moon. Therefore, the calendar date for what day is Passover celebrated might refer to an eight-day period in communities outside of Israel.
Key Dates of the Festival
While the holiday spans several days, the specific high points occur on particular dates of Nisan. The ceremonial search for chametz (leavened bread) takes place on the 14th of Nisan, just as the holiday begins. The first Seder, a ritual feast, occurs on the first night (or first two nights outside Israel), which is the 15th of Nisan. The final Seder happens on the 16th or 17th for those observing an eight-day festival, and the holiday concludes with the final day of Passover, the 21st or 22nd of Nisan.
