The Gregorian calendar, used by most countries in the western world, was initially decreed by Pope Gregory XIII on 24 February 1582. The Gregorian calendar was first proposed by Aloysius Lilius because the mean year in the Julian Calendar was slightly long, causing the vernal equinox to slowly advance earlier in the calendar year.

On 5 October 1582, the Gregorian calendar was actively adopted in the western world for the first time. It needed an adjustment to correct 11 accumulated days from the Julian calendar. The day after Thursday, 4 October 1582 was Friday, 15 October 1582, effective in most Catholic countries such as Italy, Poland, Spain and Portugal. Non-Catholic countries such as Scotland, Britain and its colonies still used the Julian calendar up until 1752, and some Asian countries were still using the Julian calendar up until the early twentieth century.

What event marks the start of Gregorian calendar?

The calendar is intended to mark the number of years since the death of King Herod the Great. The Roman abbot Dionysus Exiguus devised the new Christian calendar in 533. He knew that it was impossible to say when Jesus was born, but he knew, or thought he knew, when Herod died. So, he chose to begin his Christian calendar on the year of Herod's death, and he based this on the reign of the Roman emperor Augustus. Unaware that Augustus only adopted that name four years after his reign began, going by his birth name of Octavius until then, Exiguus commenced his calendar just 4 years too late.
