Day

The Jews reckoned the day from sunset to sunset (Lev. 23:32).

It was originally divided into three parts (Ps. 55:17).

"The heat of the day" (1 Sam. 11:11; Neh. 7:3) was at our nine o'clock, and "the cool of the day" just before sunset (Gen. 3:8).

Before the Captivity the Jews divided the night into three watches,
(1) from sunset to midnight (Lam. 2:19);
(2) from midnight till the cock-crowing (Judg. 7:19); and
(3) from the cock-crowing till sunrise (Ex. 14:24). In the New Testament the division of the Greeks and Romans into four watches was adopted (Mark 13:35).
(See WATCHES.)

The division of the day by hours is first mentioned in Dan. 3:6, 15; 4:19; 5:5. This mode of reckoning was borrowed from the Chaldeans. The reckoning of twelve hours was from sunrise to sunset, and accordingly the hours were of variable length (John 11:9).

The word "day" sometimes signifies an indefinite time (Gen. 2:4; Isa. 22:5; Heb. 3:8, etc.). In Job 3:1 it denotes a birthday, and in Isa. 2:12, Acts 17:31, and 2 Tim. 1:18, the great day of final judgment.
