Sivan (Hebrew: סִיוָן, Standard Sīvan, Tiberian Sīwān; from Akkadian simānu, meaning "Season; time") is the ninth month of the civil year and the third month of the ecclesiastical year on the Hebrew calendar. It is a month of 30 days. Sivan usually falls in May–June on the Gregorian calendar.
Along with all other current, post-biblical Jewish month names, Sivan was adopted during the Babylonian captivity. In the Babylonian calendar it was named Araḫ Simanu.
