The Gregorian calendar was a Human civilization calendar used on Earth to track the passage time. The Gregorian calendar is very similar to the Julian calendar, as it was devised as an improvement upon that system.
History and specifics[]
The Gregorian calendar was a system for measuring one solar year on Earth. This improvement upon the Julian calendar was used as a standard by Humans throughout the planet's Western hemisphere from 15 October 1582 until the adoption of stardates, although conversion from stardates to Earth year dating was common in practice. (ST novel: Excelsior: Forged in Fire)
As the keepers of time-related issues in and around the Federation, the Federation Department of Temporal Investigations can readily convert to and from Gregorian dates. (DTI novel: Watching the Clock)
In a lesser capacity, the Gregorian calendar was still used by Humans to define years as late as 24th century. The calendar year dates could be identified as taking place in the Common Era (CE) to differentiate from years before the calendar's zero point, which were annotated as Before the Common Era (BC or BCE). The stardate 58188.4 was equivalent to Tuesday, 10 March 2381 at 18:32 UTC, and stardate 58193.8 was equivalent to Thursday, 12 March 2381 at 18:27 UTC. (TTN novel: Taking Wing; DTI novel: Watching the Clock)
- Although the Federation ostensibly has converted away from current-day time measurement, a great many Gregorian style-dates are presented in Star Trek. The first chapter of Watching the Clock presented dates identified as Gregorian calendar reckoning. Subsequent chapters were dated using other calendars from various worlds.
