2025 Projected Holy Day Calendar and Guidelines for Observance

These Projected Dates have been provided through a collaboration of the Levitical Calendar Committee (LCC) and the One Nation Calendar Coalition (ONCC). This guide provides essential information regarding the calculation of holy days and the community resources available for faithful observance.

Understanding Calendar Notation

The asterisk (*) means the Holy Day begins at sunset on the day before the date listed, and continues for 24 hours, until sunset on the following day. Example: If the Feast of Weeks (Chag Shavuot) is listed as *June 12th then the holy day begins on June 11th at sunset, and lasts until June 12th at sunset.

To assist with further inquiries, you can find answers to Frequently Asked Questions about our Holy Day Calendar within our community resources.

Dietary Rules and Observance Positions

Proper observance involves specific dietary requirements and communal standards. You are encouraged to learn more about our community’s Dietary Rules for Chag HaMatsot (updated Apr 2025) and read the extensive research behind the laws of the Pesach/Chag diet (updated Apr 2025).
