Sukkah 54b Part 2/5

AI summary (may contain mistakes)

Can the first day of Succos fall on a Friday? The Gemara says it never does, because Yom Kippur would then fall on Sunday, so Rosh Hashanah is pushed off by making Elul thirty days. A Mishnah on chelvei Shabbos and a beraisa brought by Rabbi Zeira both seem to put Yom Kippur on Sunday, and the Gemara sets them with Acherim. Our Mishnah, by contrast, holds that Chazal can adjust the calendar.

Key points

• With Erev Pesach on Shabbos, the tekios come to 51 or 57, depending on whose view is followed.
• The Gemara answers that the Mishnah counts only cases that come every year.
• The Gemara says the first day of Succos never falls on Friday, since Yom Kippur would be Sunday.
• In Eretz Yisrael, Rabbi Zeira heard that the beraisa on havdalah follows only Rabbi Akiva.
• Acherim, meaning Rabbi Meir, hold that the full and short months of the calendar cannot be changed.
