How do historians determine if a year is zero?
Historians. Neither the choice of calendar system (whether Julian or Gregorian) nor the era ( Anno Domini or Common Era) determines whether a year zero will be used. If writers do not use the convention of their group (historians or astronomers), they must explicitly state whether they include a year 0 in their count of years,…
When did the first year zero come into use?
