"Greek planetary names [for the days of the week] ... are attested for the early centuries of our era, but their use was apparently restricted to certain circles; at any rate they never became popular. In Rome, on the other hand, the planetary names became the established popular terms, too strongly intrenched to be displaced by the eccl[esiastical] names, and spreading through most of western Europe." [Buck]
From the beginning, time was divided into weeks, each consisting of six days of working and one of rest (Gen. 2:2, 3; 7:10; 8:10, 12; 29:28). The references to this division of days becomes afterwards more frequent (Ex. 34:22; Lev. 12:5; Num. 28:26; Deut. 16:16; 2 Chr. 8:13; Jer. 5:24; Dan. 9:24-27; 10:2, 3). It has been found to exist among almost all nations.
