Siman 104

(1) His birth was in the holy community of Mezhibuzh, and he entered the covenant of circumcision on Shabbat HaGadol [the Great Sabbath]. And all his years, as is heard, were approximately forty years, a little less — for in his fortieth year he passed away and departed on high in the month of Eisonim [Tishrei], on the Festival, on the third day, the fourth day of Sukkos, the 18th of Tishrei 5571 [1810], in Uman, the city he chose while yet alive to lie in, as explained elsewhere (below #191, 197, 217). And afterwards I heard that his years were no more than thirty-eight and a half years, and as it appears, this is the truth. (It is known that in the year 5532, Rosh Chodesh Nisan fell on the Sabbath — and that is the day Rabbainu o.b.m. was born, according to both of the above opinions.)
