The months are combined into 12 normal years with 12 months each and 7 leap years with 13 months each.The year consisted of four quarters, each of 91 days. One theory is that each month consisted of 30 days then one extra day was added at the end of each quarter to bring the total to 91 days.Another theory is that each quarter had two months of 28 days and one month of 35 days.Every worker had one day off every week, but there was no fixed day of rest.On 1 September 1931 this was replaced by a 6-day week with a fixed day of rest, falling on the 6th, 12th, 18th, 24th, and 30th day of each month (1 March was used instead of the 30th day of February, and the last day of months with 31 days was considered an extra working day outside the normal 6-day week cycle).
