Kislev or Chislev (Hebrew: כִּסְלֵו‎, Standard Kīslev Tiberian Kīslēw),[1] is the third month of the civil year and the ninth month of the ecclesiastical year on the Hebrew calendar.

In the Babylonian calendar its name was Kislimu.

In a regular (kesidran) year Kislev has 30 days, but because of the Rosh Hashanah postponement rules, in some years it can lose a day to make the year a "short" (chaser) year.

In Jewish Rabbinic literature, the month of Kislev is believed to correspond to the Tribe of Benjamin.
