Chis´lev () is the name of that month which is the third of the civil, and the ninth of the ecclesiastical year of the Jews, and which commences with the new moon of our December.

The memorable days which were observed in this month were:—The feast of the dedication of the Temple, in commemoration of its being purified from the heathen abominations of the Syrians, which was celebrated by illuminations and great demonstrations of joy for eight days, beginning from the 25th of this month (): and a fast on account of Jehoiakim having, in this month, burnt the roll containing Jeremiah's prophecy (). There is some dispute whether this fast was observed on the 6th or on the 28th of the month. It is an argument in favor of the earlier day that the other would fall in the middle of the eight days' festival of the dedication.
