Cyclopedia of Biblical, Theological and Ecclesiastical Literature [5]

(properly עֵת , a fixed Time,' Καιρός , often rendered "time" in general, and not specific of a portion of the year). The general division of the year by the Hebrews was into two seasons, "Summer and Winter" (Psalm 64:17;  Zechariah 14:8); but they appear also to have conveniently divided the year into six special seasons: "seed-time and harvest, and cold and heat, and summer and winter" ( Genesis 1:14;  Genesis 8:22). The same division obtains among many Oriental nations, as the Hindus :and Arabians, at this day. According to this division of the seasons in Palestine, they would seem to have been distributed in the following order: Summer, from the,middle of August to the middle of October; Seed-time(from the middle of October to the middle of December; Winter, from the middle of December to the middle of February; Cold, from the middle of February. to the middle of April; Heat, from the middle of April to the middle of August. (See Agriculture).
