**Helek**

The **helek** ( Hebrew חלק, meaning "portion", plural *halakim* חלקים) is a unit of time used in the calculation of the Hebrew calendar. Other spellings used are *chelak* and *chelek*, both with plural *chalakim*.

The hour is divided into 1080 halakim. A helek is 3⅓ seconds or / minute. The *helek* derives from a small Babylonian time period called a *she*, meaning '"barleycorn", itself equal to / of a Babylonian time degree (1° of celestial rotation).

*shes*per degree / 24 hours = 1080

*shes*per hour.

The Hebrew calendar defines its mean month to be exactly equal to 29 days 12 hours and 793 halakim, which is 29 days 12 hours 44 minutes and 3⅓ seconds. It defines its mean year as exactly 235/19 times this amount.
