Shabbat HaChodesh / שבת החדש
Shabbat HaChodesh (“Sabbath [of the] month” שבת החודש) precedes the first of the Hebrew month of Nisan during which Passover is celebrated. Exodus 12:1-20 and the laws of Passover. On the first day of Nisan, God presented the first commandment of how to “sanctify the new moon” (kiddush hachodesh) for the onset of Rosh Chodesh and thus Nisan becomes the first month of the Jewish year (counting by months.).
Shabbat HaChodesh begins at sundown on Fri, 24 March 2017.
