The Gregorian calendar, like the Julian calendar, is a solar calendar with 12 months of 28–31 days each.

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).

They acceded to the Gregorian calendar rules for Easter only in 1776. Britain adopted the New Style in 1752 and Sweden in 1753, although the Swedes, because they had in 1740 followed the German Protestants in using their astronomical methods for determining Easter, declined to adopt the Gregorian calendar rules until 1844.
The result was that Catholic Europe—Austria, Spain, Portugal, Italy, Poland, and the Catholic states of Germany—suddenly jumped ahead of the rest of the continent by 10 days, and traveling across a border often meant traveling forward or backward on the calendar. Eventually, non-Catholic countries did begin to adopt the Gregorian calendar.
