The sixth of Sivan is the yahrzeit of R. Yisrael Baal Shem Tov, founder and first leader of the general chassidic movement from the year 5494 (תצ"ד; 1734) until his passing on Wednesday, the first day of Shavuos,1 5520 (תק"כ; 1760). His resting place is in Mezhibuzh.

In allusion to the day of his passing, the Alter Rebbe once quoted a phrase from Rashi in a figurative sense: “On the fourth day of the week the luminaries were taken away.”2
