The true origins of April Foolsâ Day are unknown. Some suggest it originated in France with the Edict of Roussillon in 1564, while others believe it relates to the equinox that occurs on March 20 or 21 (the Northern Hemisphereâs vernal equinox and the Southern Hemisphereâs autumnal equinox), a time when people are fooled by sudden changes in the weather. Some also believe that the tradition of playing pranks was popularized after Geoffrey Chaucerâs The Canterbury Tales.
