The Jewish Calendar that dates from the time of Hillel II (359 CE, AM4119) is the official calendar of the State of Israel. It is used to determine the dates for Passover provided here. It is a lunisolar calendar based on computations rather than visual observations (visual observations of the young crescent Moon were used in ancient times). Passover begins on the same liturgical date, Nisan 15, each year. The dates for Passover for the years 2000-2029 using the civil calendar (CE=Common Era, or Gregorian) are:
|Year CE||Passover||Year CE||Passover||Year CE||Passover|
|2000||April 20||2010||March 30||2020||April 9|
|2001||April 8||2011||April 19||2021||March 28|
