A standard year will have 52 weeks of 7 days. This totals 364 days. Rather than a leap-week added at the end of every 5 or 6 years, every 292nd week is repeated. This repeated week is the defining characteristic of the Double Week Calendar . Numerical Days of the month would no longer be necessary because dates can easily be referenced by the day of the week and the ordinal count of that day in the month (ex. "the fourth Thursday of November"). Because every year has the same 52 weeks, such a reference would always refer to the same day.
