Solar Common Calendar

The Solar Common Calendar (SCC) is the standard calendar of human-settled space. As most worlds, habitats and systems use local calenders that can vary widely in day and year lengths, SCC is employed to avoid confusion when scheduling flights, meetings and the like between them. News, social media and archives also use it as their standard calendar.

Solar Common Era (SCE) is the current era, and the same as the old Earth standard Common Era (CE). It was renamed to fit the scheme used for the calendar and standard time, though the change also helps distinguish it better from local Common Eras.

Solar Common Time (SCT) is the international standard time, and the same as the Sol-bound interplanetary standard Barycentric Coordinate Time (TCB). In 3940 SCE, TCB/SCT differs from the old Earth-bound standard Coordinated Universal Time (UTC) by approximately +15.67 minutes, as barycentric time moves faster by roughly .49 seconds per Earth year.
