The Carey calendar, developed by Henry Frank Carey, is a fixed calendar system proposing a consistent year-round structure. Each date falls on the same day of the week every year, simplifying scheduling and international coordination. A typical example involves four quarters of 91 days, each divided into three months of 30, 30, and 31 days, with an extra day outside the week structure at year’s end and, in leap years, another such intercalary day mid-year. This structure aims to eliminate variations inherent in the Gregorian calendar.
Fixed calendars offer potential advantages for businesses, organizations, and individuals by streamlining operations and long-term planning. Predictable dates simplify accounting cycles, academic calendars, and project management timelines. Historically, numerous calendar reform proposals have sought to address perceived inefficiencies of the Gregorian system, with Carey’s design being one such contribution to this ongoing discourse. These reforms often aim for greater consistency and predictability.
