According to Rabbi Judah (cited in the Talmud, Bava Metzia 106b), Tevet 29 marks the end of winter. (As per Genesis 8:22, the year consists of six 2-month "seasons": seedtime, harvest, cold, heat, summer and winter.)

Rabbi Yitzchak Kaduri, known in recent years as "the eldest of the Kabbalists," in the Holy Land, was born in Baghdad, Iraq in 1898. As a youth, he studied under the great "Ben Ish Chai" (Rabbi Yosef Chaim of  Baghdad, 1840-1913) and was regarded as an illu (prodigy) by the sages of the venerable Baghdad Jewish community. In 1922, Rabbi Yitzchak emigrated to the Holy Land and joined the ranks of the Jerusalem Kabbalists, even as he earned his living for many years as a bookbinder. Over the years his fame grew, and thousands flocked to him to receive his counsel and blessing.

Rabbi Kaduri passed away on the 29th of Tevet of 2006, age 108. Hundreds of thousands attended his funeral in Jerusalem.
