What Was The First Calendar. It was more accurate than the previously used roman. Ancient historian and greek biographer plutarch, wrote in c.e.
The romans called the first of the month “kalends,” the origin of the english word “calendar.” they called the day before the middle of the month the “ides,” and the eight days before the ides (or nine days counting inclusively) they called “nones.” Starting in 46 b.c., roman emperor julius caesar implemented the creation of a new calendar — the julian calendar.
