Long Calendars
Archaeologists have reconstructed methods of timekeeping that go back to prehistoric times at least as old as Neolithic. The natural units for timekeeping used by most historical societies are day and the solar year. Calendars are explicit schemes used for timekeeping. The first historically attested calendars date to Bronze Age, dependent on the development of writing in ancient Near East.
