Shabbat Mevarchim

On the Shabbat before Rosh Chodesh (Shabbat Mevarchim), most congregations announce the coming month, the molad, and which day or days Rosh Chodesh falls on. Tishrei is the exception: Rosh Hashanah is not announced, since it is the start of the year itself.

Frequently Asked Questions

What is the molad?

The molad is the calculated moment of the new moon's "birth" that anchors each Hebrew month. It is computed with fixed chalakim arithmetic, not observed directly.

What is Shabbat Mevarchim?

The Shabbat before Rosh Chodesh, when many congregations announce the molad and the coming Rosh Chodesh day(s) during services. There is no announcement before Tishrei (Rosh Hashanah).

Why is Rosh Chodesh sometimes two days?

When the outgoing month has 30 days, its 30th day is also observed as the first day of Rosh Chodesh, followed by the 1st of the new month as the second day.
