All of the Biblical Feast Days begin at sunset on the day before the date listed and continue for 24 hours until sunset on the following day. For example: Passover is on Monday April 21, 2008 meaning that it will actually start the evening of Sunday April 20th 2008. This also means that Ressurection Day falls on Thursday April 24th 2008, starting on Wednesday April 23rd, 2008 at sundown and last until sundown Thursday April 24th at sundown.

The Rabbinic Calendar in use by myriads of Jews world wide is incorrect and off +/- one or two days about 40% of the time. The Rabbinical Calendar in use today is much like the calendar of Hillel-II, both of which were made by men and considered the most reliable for their time being as Jews were exiled from the promised land.

The Jewish people do not need this man-made calendar anymore. Jews have returned to the promised and can now visually see the new moon with their own eyes. The Kohanim agree and have even studied the New Moon records kept by the Karaites, but unfortunately, the Rabbi's are slow to let go of tradition.

Last year the Rabbi's added adar-II to the rabinical calendar and celebrated Purim a month late. That posed a huge problem in that the barly was Aviv which means that the following month was not the 13th month but the first month of the following year. Let me explain it this way, Rabbinical Jews (including Messianic Jews) celebrated Purim on Passach (Passover) last year.
