Where *asterik appears -The Biblical Holy Day begins at sunset on the day before the date listed and continues for 24 hours until sunset on the following day.

The O.N.C.C. is committed to sending two representatives to Israel each year to proclaim “First Fruits” (Barley) in it’s Abib state, thus declaring the month of Abib. [Exodus 12:2; Deut.16:1].  If you would like to make a monetary donation to help offset the travel cost of our group members, please make a Donation today!  Your contributions are greatly appreciated.
