when is passover celebrated on the jewish calendar
Passover Passover commences on the 15th of the Hebrew month of Nisan and lasts for either seven days (in Israel and for Reform Jews and other progressive Jews around the world who adhere to the Biblical commandment) or eight days for Orthodox, Hasidic, and most Conservative Jews (in the diaspora).[7][8] In Judaism, a day commences at dusk and lasts until the following dusk, thus the first day of Passover only begins after dusk of the 14th of Nisan and ends at dusk of the 15th day of the month of Nisan. The rituals unique to the Passover celebrations commence with the Passover Seder when the 15th of Nisan has begun. In the Northern Hemisphere Passover takes place in spring as the Torah prescribes it: "in the month of [the] spring" (בחדש האביב Exodus 23:15). It is one of the most widely observed Jewish holidays.
Year 6000 According to classical Jewish sources, the Hebrew year 6000 (from sunset of 29 September 2239[2] until nightfall of 16 September 2240[3] on the Gregorian calendar) marks the latest time for the initiation of the Messianic Age. The Talmud,[4] a Midrash,[5] and the Kabbalistic work, the Zohar,[6] state that the 'deadline' by which the Messiah must appear is 6,000 years from creation. According to tradition, the Hebrew calendar started at the time of Creation, placed at 3761 BC.[7] The current (2018/2019) Hebrew year is 5779.
