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 The seven-day week seems to have been adopted, at different stages, by the Persian Empire, in Hellenistic astrology, and (via Greek transmission) in Gupta India and Tang China.[b][citation needed]
