Historical Context
The Gregorian calendar emerged in 1582, introduced by Pope Gregory XIII to reform the Julian calendar. The Julian calendar miscalculated the solar year by 11 minutes, leading to a drift over centuries. The Gregorian reform corrected this by establishing a simpler formula to determine leap years, thus retaining seasonal accuracy. Countries adopted the Gregorian calendar at different times, with some not fully transitioning until the 20th century. Today, it stands as the international standard for civil use, impacting everything from business to cultural celebrations.
