Two Days of Yom Kippur

A valid question which I am sure not many people are asking, for obvious reasons, is why don’t Jews outside of Israel observe two days of Yom Kippur. We already known that in the Talmud the question was discussed and Ravah was known to observe two days of Yom Kippur (see bRosh HaShannah 21a), but what about everyone else. Considering the amount of difficulty which many people have with fasting one day, it is not surprising that two days of Yom Kippur never caught on. While this may be true for the majority of Jews, during the Medieval Period there definitely were some Jews, it is not clear how many, who took it upon themselves to observe Yom Kippur for two days.

There is a tradition found in numerous collections from the “School of Rashi” about two sages, R. Yitzhak HaLevi and R. Yehuda b. R. Baruch (there are variations as to the exact names) who fasted on Yom Kippur for two days (see Sefer HaPardes p. 234; Siddur Rashi par. 204; Mahzor Vitry, p. 381 in the Horowitz ed.; Sefer HaRavyah par. 886, p. 659). Both of these rabbis were scholars from Worms and Mainz, and were students of Rabbeinu Gershom Meor Hagolah (“the Light of the Exile”) and at least R. Yitzhak HaLevi is known to have been a teacher of Rashi (see Aptowitzer, Mavo Sefer haRavyah, p. 367). Also see the R. Isaac of Vienna’s Or Zarua where he says that he wouldn’t think too highly of those who observed Yom Kippur for two days, since it was in his eyes dangerous, until he saw his teacher R. Judah the Pious, R. Yehudah HeHasid, and the Ravyah himself observe it for two days (Or Zarua, vol. 2, par. 281).

One Response to “Two Days of Yom Kippur”

  1. 1
    Menachem Mendel:

    The common answer given for why Yom Kippur is only observed for one day is that even in ancient times, when Rosh Hodesh was determined al-pi re’iah, people relied on the fact that for the most part, Rosh Hashana would occur on the first of the two eligible days. See Ritva on Rosh Hashana 18a, as well as R. Y.M. Tukaczinski’s Ir Haqodesh ve-hamiqdash v. 3 (the chapter dealing with two days Rosh Hashana)

    The Rav has instructions in the Shulchan Aruch about how to do it (keep two days) and discusses it in general.

    We’re can be Meikal because of Sfek Yoma {D’rabanan} and the fact that Rosh Hashana {new moon} will most always fall out on thirtieth day of Elul, making Yom Kippur usually on the earlier day.
