A six-day week was used in the Akan calendar and Kabiye culture in West Africa until 1981. Several cultures used a five-day week, including the Javanese calendar and the traditional cycle of market days in Korea.[citation needed] The Igbo have a "market week" of four days. Evidence of a "three-day week" has been derived from the names of the days of the week in Guipuscoan Basque.[1]
