Fun Trivia: When Pope Gregory instituted the Gregorian Calendar, the Julian Calendar had been followed for over 1500 years, and so the calendar date had already drifted by over a week. Pope Gregory re-synchronized the calendar by simply eliminating 10 days: in 1582, the day after October 4th was October 15th!
Trivilialidades: Cando o papa Gregorio instituíu o calendario gregoriano había 1500 anos que se seguía o calendario xuliano, polo que a data do calendario xa se desprazara máis de unha semasna. O papa Gregorio volveu a sincronizar o calendario sinxelamente eliminando dez días: en 1582 o día despois do 4 de outubro foi o 15 de outubro!
