Crescent Moon and ABIB (Yellowish-Green) Barley Watching Tools

Last updated Mar 6, 2012.

Ancient Hebrew: months begin with a crescent moon, and years begin with ABIB. Currently the average length of a lunar month is 29.530588 days. This means from crescent moon to crescent moon there are 29 or 30 (whole) days: depending on the thickness of the sliver. The crescent moon can be predicted each month using modern astronomy—but a number of people like to sight the moon as confirmation. The moon rises in the east, and sets in the West—just like the sun. The following are some useful crescent moon and ABIB watching tools:
