In 1582, when Pope Gregory XIII introduced his Gregorian calendar, Europe adhered to the Julian calendar, first implemented by Julius Caesar in 46 B.C. Since the Roman emperor’s system miscalculated the length of the solar year by 11 minutes, the calendar had since fallen out of sync with the seasons. This concerned Gregory because it meant that Ea...
The Julian calendar included an extra day in February every four years. But Aloysus Lilius, the Italian scientist who developed the system Pope Gregory would unveil in 1582, realized that the addition of so many days made the calendar slightly too long. He devised a variation that adds leap days in years divisible by four, unless the year is also d...
Despite Lilius’ ingenious method for syncing the calendar with the seasons, his system is still off by 26 seconds. As a result, in the years since Gregory introduced his calendar in 1582, a discrepancy of several hours has arisen. By the year 4909, the Gregorian calendar will be a full day ahead of the solar year.
Though Pope Gregory’s papal bull reforming the calendar had no power beyond the Catholic Church, Catholic countries—including Spain, Portugal and Italy—swiftly adopted the new system for their civil affairs. European Protestants, however, largely rejected the change because of its ties to the papacy, fearing it was an attempt to silence their movem...
According to some accounts, English citizens did not react kindly after an act of Parliament advanced the calendar overnight from September 2 to September 14, 1752. Rioters supposedly took to the streets, demanding that the government “give us our 11 days.” However, most historians now believe that these protests never occurred or were greatly exag...
Julius Caesar’s calendar reform of 46 B.C. instituted January 1 as the first of the year. During the Middle Ages, however, European countries replaced it with days that carried greater religious significance, such as December 25 (the anniversary of Jesus’ birth) and March 25 (the Feast of the Annunciation). The latter, known as Lady Day because it ...
Apr 17, 2024 · The Gregorian calendar differs from the Julian only in that no century year is a leap year unless it is exactly divisible by 400 (e.g., 1600 and 2000). A further proposed refinement, the designation of years evenly divisible by 4,000 as common (not leap) years, would keep the Gregorian calendar accurate to within one day in 20,000 years.

Mar 12, 2024 · This shift required that September 2, 1752, be followed by September 14, 1752, resulting in widespread confusion and, according to some accounts, protests. The adoption of the Gregorian calendar outside Europe occurred over an even longer period, influenced by colonization, trade, and the spread of European power.
For example, the Calendar (New Style) Act 1750 introduced the Gregorian calendar to the British Empire. Thus, in 1752, Great Britain and its territories switched from the Julian calendar to the Gregorian calendar. It was necessary to align the calendar used in England with the rest of Europe, therefore it was decided that the 2nd of September ...
Dec 7, 2020 · The Gregorian calendar was instituted by Pope Gregory XIII in 1582 and quickly adopted by much of Catholic, but not Protestant, Europe. The reform altered the Julian, or Old Style, system of leap years and, by removing ten days from October 1582, adjusted the timing of the Easter observance so that it better coincided with the spring season.
Evolution of New Year Celebrations Over time, as societies and cultures evolved, the Christian church and later the Gregorian calendar reforms played a significant role in shaping the way New Year’s was celebrated. The melding of various cultural customs, including those of pagan origin, led to the modern-day festivities observed globally.
