Parashat Vaeira 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... This Shabbat - January 8th - is Rosh Chodesh Shvat. We add YA'ALEH V'YAVO to the Amida of Maariv, Shacharit, and Mincha, and we say a special combination-Musaf for Shabbat-Rosh Chodesh. YA'ALEH V'YAVO is added into each BIRKAT HAMAZON right after R'TZEI, as is a Rosh Chodesh HARACHAMAN, right after the SHABBAT HARACHAMAN. Omission of YA'ALEH V'YAVO at Maariv does not require repeating the Amida; at Shacharit and Mincha it does. Similarly, If one says the regular Shabbat Musaf Amida (or the weekday Rosh Chodesh Musaf), the Amida is "fatally flawed" and must be repeated, correctly. Omission of YAALEH V'YAVO from Birkat HaMazon does NOT require repeating, but omitting R'TZEI does require repetition (except for Seuda Shlishit). As we saw in last week's TT, Rosh Chodesh Shvat (and TU b'SHVAT) fall on Shabbat most often, almost 30% of the time. Never on Sunday or Friday. First opportunity for Kiddush L'vana would be Sunday night after 6:20pm, but be that time the Moon will have set. Therefore, Monday night. [The Vaeira Homepage] |
