Shabbath haChodesh

Shabbat HaChodesh ("Sabbath of the month" שבת החודש) precedes the first of the Hebrew month of Nisan during which Passover is celebrated. Shemot 12:1-20 and the laws of Passover. On the first day of Nisan, G.d 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.
