The Hebrews followed a lunar calendar. The month began when the thin crescent of the new moon was first visible at sunset. The day of the new moon that ushered in a new month was considered Holy. The Autumnal equinox was viewed as “at the end of the year” (Exo 23:16 NIV); and the Spring, or vernal equinox, was called “the return of the year” (1 Kin 20:26).
The Hebrews also commonly indicated the time of year by the Season rather than by the names of the months. In Palestine the year divided loosely into the dry season (April – September) and the rainy Season (October – March), and these were sub-divided into seed-time (November – December) and Harvest (April – June).
We also find calendar designations by agricultural activities such as: “Wheat harvest” (Gen 30:14) “Barley Harvest” (2 Samual 21:9); or the “earing time” (Exo 34:12)
In the next DID YOU KNOW? we will give the different months of the Jewish Calendar.
