where did the 7 days of the week come from
Week Friedrich Delitzsch and others suggested that the seven-day week being approximately a quarter of a lunation is the implicit astronomical origin of the seven-day week[10] , and indeed the Babylonian calendar used intercalary days to synchronize the last week of a month with the new moon.[11] According to this theory, the Jewish week was adopted from the Babylonians while removing the moon-dependency.
777 (number) Christian denominations consider seven to be a holy number because Genesis says that God rested on the 7th day and man was created on the 6th day.[4] Because God rested on the 7th day, that is the reason for the observance of the Hebrew Sabbath on the last day of the week. The 7th day of the week is indicated on the Hebrew Lunar calendar containing 13 months of four weeks each. According to the American publication, the Orthodox Study Bible, 777 represents the threefold perfection of the Trinity.[5]
