444 years ago, on the 15th of October 1582, the Gregorian calendar was first adopted causing many Catholic European countries to jump from the 4th to the 15th. The calendar was decreed by Pope Gregory XIII to regain a correct calculation of the date of Easter. #otd #history 🗃️

Lunario Novo, Secondo la Nuova Riforma della Correttione del l'Anno Riformato da N.S. Gregorio XIII, printed in Rome by Vincenzo Accolti in 1582, one of the first printed editions of the new calendar.
