WORD OF THE MONTH

A weekly feature of Torah Tidbits to help clarify practical and conceptual aspects of the Jewish Calendar, thereby better fulfilling the mitzva of HaChodesh HaZeh Lachem... 

The Molad of Nissan was Shabbat (MAR 24) 17h 41m 10p. Add 14 days 18h 22m to find the Nigud (opposition, full moon) of Nissan, and you get Sunday (APR 8) 12h 3m 10p – that's a little after noon on the first day of Pesach. Therefore, last opportunity for Kiddush L'vana this month is Seder night (all night).
