Question: Will you please explain why we begin to say the prayer of Tal u’Matar on the evening of December 4 or 5 – that is, based on the secular calendar? Also, if one traveled to Eretz Israel, where they start to say it earlier, what is he to do when he is there, and when he returns, if he returns before the time we normally commence to say in the Diaspora?

Synopsis: We cited from Rabbi Abraham Rapoport of the London Beth Din, who is cited in great detail by the late Chief Rabbi of England, Lord Immanuel Jakobovits, wherein we find why specifically the Diaspora starts to request rain from December 4 or 5 (depending on the year). Rabbi Rapoport cites the Tannaic dispute of Shmuel and R. Adda b. Ahava, with the former arriving at a general figure that fixed the solar year at 365 days and 6 hours, giving each of the four seasons 91 days and 7-1/2 hours. The latter disputed this and arrives at the much more precise figure of 365 days, 5 hours, 997 parts (one hour has 1,080 parts), and 48 moments (1 part has 76 moments) for the year, or 91 days, 7 hours, 519 parts, and 31 moments for the season. Rabbi Jakobovits, after much discussion and elaborating on all these calculations and the need to correspond to our present-day Gregorian (solar) calendar, determines that the date which has to be 60 days after the autumnal equinox (Ta’anit 10a) is either December 4th or 5th (depending whether it is a non-leap year or a leap year).

Answer: The Mechaber (Orach Chayyim 117) in his Shulchan Aruch, as we noted, states the different start dates for the request of V’tein Tal u’Matar as 7 Marcheshvan in Eretz Yisrael and the 60th day from the beginning of the autumn season (the autumnal equinox) – Tekufat Tishrei in the Diaspora. These, he notes, are to be steadfastly kept by each in its place.
However, he rules (Orach Chayyim 117:2) that individuals who are in need of rain in the summer are not to request it in the blessing of Birkat HaShanim, but rather in Shome’ah Tefillah. To emphasize, he notes that even a city as large as Nineveh or even an entire country like Sefarad (Spain in its entirety) or Ashkenaz (Germany and France) in its entirety – even where they are totally in need of rain – are considered as individuals in this regard and thus they may only request in Shome’ah Tefillah. He further notes that in the instance where one was in a land where there was total need for rain in the summer and he mistakenly requested rain in Birkat HaShanim, he must repeat his prayer – Shemoneh Esreh, however as a tefillat nedavah, a voluntary prayer, of course without mention of a request (this second time) in Birkat HaShanim.
Rema (ad loc) in both his glosses and emendations notes that there is no requirement at all to repeat the prayer. This he cites in the name of Mahari Assad but notes that Ramban and Ran follow the view of Rosh – whom both Tur and the Mechaber (Beit Yosef) follow (as the Mechaber stated above).
Mishna Berurah (117sk8) notes the reason that we do not request in the Diaspora or in Eretz Yisrael during the summer is because as a general rule, rain at that time causes damage to crops that might still be on the ground. He also notes that the time we conclude the winter request of V’tein Tal u’Matar is the same everywhere, both in Eretz Yisrael and in the Diaspora.
Many of the recent and contemporary authorities discuss this matter at length – as to what an Israeli Jew who finds himself in the Diaspora before their time for their request of rain (December 4 or 5) but after the 7th of Marcheshvan is to do, and conversely what a Jew who dwells in the Diaspora who now finds himself in Israel at that same time is to do.
The Debrecener Rav, Rabbi Moshe Stern zt”l (Responsa Ba’er Moshe vol. 7:117, p. 193) cites many sources in the course of his lengthy and thorough discussion of this matter. Amongst those he cites is Mahari’kas (Rabbi Jacob b. Abraham Castro-Sarmento 1525-1610), who rules that a resident of Eretz Yisrael who departs the land with the intent to return, even though he will not return during the rainy season, is to request rain like those residing in the land of Israel.
Radbaz (Responsa 58), also cited by the Debrecener Rav, rules differently – that if he intends to return in the time when they request rain in Eretz Yisrael, then he too requests like those in Eretz Yisrael; however, if he has a wife and children in Eretz Yisrael, then even if he will not return during the entire rainy season, he nevertheless begins his request when they do. He adds that this is so as long as his intention is to return within that year (I believe he means within the twelve-month period).
