where did the term 7 year itch come from
The seven-year itch The phrase was first used to describe an inclination to become unfaithful after seven years of marriage in the play The Seven Year Itch by George Axelrod, and gained popularity following the 1955 film adaptation starring Marilyn Monroe and Tom Ewell. In his 1913 novel The Eighth Year, Philip Gibbs attributes the concept to the British judge Sir Francis Jeune.
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.
