Key Theories on the Origin of April Fools’ Day
French Calendar Reform (16th Century):
One popular theory links April Fools’ Day to adopting the Gregorian calendar in 1582. Before this reform, under the Julian calendar, New Year’s Day was celebrated around late March or early April. When France officially moved New Year’s Day to January 1 by the Edict of Roussillon in 1564, some people either resisted or were unaware of the change and continued to celebrate the old date. These individuals were mocked as “April fools” and subjected to pranks
Medieval and Ancient Festivals:
The day may also have roots in earlier celebrations like the Roman festival Hilaria (March 25), which involved games, disguises, and mockery, or the medieval Feast of Fools, where social roles were humorously inverted
Another possibility is its connection to springtime unpredictability, such as weather changes around the vernal equinox (March 21), which may have inspired themes of trickery
