Gregorian Calendar
I believe all cultures used a 7 day week as a basis, plus or minus a few hours here and there for what constitutes a 'day'. --Robert W King 13:33, 5 June 2007 (CDT)
- I think the ancient American cultures such as Aztec and Mayan used 13 day and 20 day weeks not the 7 days week. Revolutionary France introduced a 10 day week and 10 days were also used by and ancient Egypt. The USSR introduced a 5 day week in 1929 which was changed to 6 day weeks in 1931 then reverted to 7 day weeks in 1940. Derek Harkness 14:23, 5 June 2007 (CDT)
