Today, 376 years ago, in the year 1644, the Tosfos Yomtov, and his family arrived in Cracow.
Rabbi Lipman Heller, known for his work Tosfos Yomtov shared his hard life with us, in his sefer Megillas Evah. Cracow was the last Rabbinical post of his life. Although he arrived there in the month of Cheshvan, it was only on Rosh Chodesh Adar I, when he received the rabbinical post.
Searching through Megillas Evah, we find that in a way, Cheshvan was his lucky month, since, throughout his lifetime it was the month of Cheshvan, when he received quite some of his rabbinical positions from other communities.
