Old Earth calendar

The old Earth calendar was an Earth calendar used for dates during the 22nd century. For example, the years 2123 and 2190 were generally placed on this calendar. (TNG: "Up The Long Ladder")

By the 23rd century, this calendar seemed no longer in use, and stardates were used instead. Since Star Trek: Enterprise was set between the two mentioned dates, it seems very likely that the dates mentioned on the series were according to this calendar system. The old Earth calendar might have been a successor to the similarly-named "Old World calendar", which based on its use for 20th century dates might simply be the 23rd century term for the currently-used Gregorian calendar.
