The Catholic origins of April Fools Day

Did you ever pull some pranks on your friends or family for April Fool’s Day?
You may have the Catholic Church to thank, according to some historical accounts.
As the Denver Catholic reports:
“It was Pope Gregory XIII who, in 1582, would unknowingly give rise to the world’s silliest holiday. He issued a decree ordering that all Christian nations adopt a standardized calendar, called the Gregorian calendar. This moved the new year from the end of March to the first of January, causing a great deal of confusion for some. Those poor saps who were ignorant to this new tradition or simply didn’t want to observe it were mocked as ‘fools.’”
According to History.com, this mocking included attaching paper fish to the back of the fools, or  “’poisson d’avril’ (April fish), said to symbolize a young, easily caught fish and a gullible person.”
Don’t be afraid to pull (good-natured) pranks on your friends either! You’d be in good company – St. Philip Neri and Blessed Pier Giorgio Frassati were both especially known for being jokesters.
