A calendar defines, among many other things, the length of each year. Calendars with different year lengths must use different numbering systems. However, within a single calendar it is possible to have several year numbering systems. This occurs for the Gregorian calendar currently in common use and also for the Julian calendar which preceded it. Calendars with identical year lengths can share a numbering system, as for several proposed reformed calendars based on Gregorian years.
