Motzei Shabbos Parshas Noach is leil zayin Marcheshvan, the night Eretz Yisroel starts saying V'sein Tal U'matar Livrocha, while Chutz La'aretz waits until sixty days after the tekufah. That raises the question of where Eretz Yisroel ends: the Golan, the Arava down to Eilat, soldiers stationed in Sinai, and the kehillos Down Under whose seasons run the other way. And once the night comes, which words are me'akeiv, and where does a person put them in if he forgot.

In this episode:

- Whether the Golan, Eilat and soldiers in Sinai start on zayin Cheshvan, and the Ramban on yishuv Eretz Yisroel in kivush Olei Mitzrayim

- The Ritva, the Ra'ah and the Orchos Chaim on starting right after Sukkos, and Rav Chaim Shabsai and the Halichos Shlomo on one who already did

- Tal, matar, livrocha and al pnei ha'adama: which words are me'akeiv, and why leil zayin is different from Ya'aleh V'yavo at night

- The hachraza and the clap before Shmoneh Esrei, and where it goes if forgotten: Bareich Aleinu, between the brachos, Shma Koleinu, or back after R'tzei

- U'lemikveh hamayim kara yamim: the Ramban on the name Yam, the galei hayam in Bava Basra, and what happened to the gvul of the yam in the Mabul

A person davening on leil Pesach slips into the weekday Shmoneh Esrei and only catches himself at Bareich Aleinu, on the one night when Mashiv Haruach has not yet stopped but V'sein Tal U'Matar already has. Far to the south, in Brazil and Australia, the seasons run the other way, and a request for rain in November can be a siman klala. And for anyone who is not sure what he said, the question is how long the doubt lasts, and whether ninety repetitions in one sitting can stand in for thirty days.

In this episode:

- Whether one who reached Bareich Aleinu in a weekday tefila on Pesach finishes with V'sein Bracha, the Magen Avraham on hachraza against the Beis Yosef, and the Mishnah Berurah and Kaf HaChaim l'maaseh

- How kehillos below the equator handle Mashiv Haruach and V'sein Tal U'Matar: the Rambam in Peirush Hamishnayos, the Rosh, the teshuva to Brazil and the Australian minhag

- Chezkas lamed yom, the ninety tefillos and the Chasam Sofer's cheshbon of 101, and whether one or two mistakes break the chazaka

- Whether knowing at the start of the tefila what to say counts, and what is a zman muflag

- Rav Shlomo Zalman on when to use the ninety times and when not to, and whether it may be done on Shabbos before zayin Marcheshvan on Motzei Shabbos

- Hamechadesh b'chol yom tamid, Rav Avraham ben HaGra on yom l'yom yabia omer v'laila l'laila yechaveh daas, and Torah by day and by night

Right before Hoshana Rabbah a man in Eretz Yisroel called with a shailah. Rain was expected over Shemini Atzeres and Simchas Torah, which in Eretz Yisroel are one day, and he was leaving to spend Yom Tov at his parents' house. He wanted to take his sukkah down before he went. The Mishnah says gamar le'echol, lo yatir es sukkaso, and the Rishonim give three different reasons for it.

In this episode:

- Rashi's ta'am, that the whole day is still for sleeping and learning in the sukkah, and why the Tur and the Mishnah Berurah bring only his reason

- Whether eating in a sukkas chaveiro is a tza'ar, and whether a son at his parents' house is echad mi'bnei beisam

- The Ran's chiddush that a person needs a sukkah kol shiv'a: a mitzvah of binyan sukkah or only a hechsher mitzvah, and why you are pocheis bo daled al daled

- Reb Shlomo Zalman and Rav Elyashiv on the Ran, the Meiri's bizuy mitzvah and prikas ol, and the Chashukei Chemed on taking down the s'chach in the rain

- Why the Torah begins with Bereishis: the Ramban on the geirushin of Adam HaRishon, the Dor HaMabul and the Dor HaFlaga, and ki ba'avodaso yinchaluha
