Rosh Chodesh: Shabbos Rosh Chodesh Is Yom Tov

AI summary (may contain mistakes)

Why does Musaf of Shabbos Rosh Chodesh, Atah Yatzarta, borrow a whole sentence from the Yom Tov nusach, said neither on Shabbos nor on Rosh Chodesh? Rosh Chodesh was once a Yom Tov, taken from the men after the Chet HaEgel and given to the women. Shabbos stands above chet, so when the two meet Rosh Chodesh is a Yom Tov again, and the Friday before is treated as Erev Yom Tov.

Key points

• Rabbi Yehuda, brought by the Tur, counts the twelve Roshei Chodashim as Yamim Tovim for the shevatim.
• Shabbos stands above chet, so the Chumash tells of Adam's Friday chet only after Shabbos.
• With no Chet HaEgel on Shabbos, Rosh Chodesh that falls on Shabbos is a Yom Tov again.
