A decimal calendar is a calendar which includes units of time based on the decimal system. For example a "decimal month" would be $1 year/10$, or 36.5 days long.

HistoryEdit

Calendar of RomulusEdit

Main article: Calendar of Romulus

The original Roman calendar consisted of ten months (however, the calendar year only lasted 304 days, with 61 days during winter not assigned to any month).[1] The months of Ianuarius and Februarius were added to the calendar by Numa Pompilius in 700 BC.[1]

Egyptian calendarEdit

The ancient Egyptian calendar consisted of twelve months, each divided into three weeks of ten days, with five intercalary days.[2]

French Republican CalendarEdit

Main article: French Republican Calendar

The French Republican Calendar was introduced (along with decimal time) in 1793, and was similar to the ancient Egyptian calendar.[3] It consisted of twelve months, each divided into three décades of ten days, with five or six intercalary days called sansculottides.[3] The calendar was abolished by Napoleon on January 1, 1806.[3]

ProposalsEdit

The Gregorian calendar, although enjoying near universal acceptance, has sometimes been criticized as being cumbersome, inefficient and culturally imperialistic; as a result a number of decimalized alternatives have been proposed as reforms.

A modern Messiah Calendar has been proposed with a 20-month year and a five-day week.

No decimal calendar proposal to date has gained a level of public acceptance sufficient to ensure its longterm success, and some have argued that the cost of any proposed conversion would far outweigh the savings that it might deliver.
