What is the connection between April Fools' Day and Chaucer?

The connection between April Fools' Day and Geoffrey Chaucer arises from a passage in his 14th-century poem "The Canterbury Tales." In "The Nun's Priest's Tale," Chaucer refers to "March 32," which some interpret as a reference to the foolishness associated with April Fool's Day. This has led to speculation that Chaucer's work may have contributed to the tradition of pranking on April 1, although the exact origins of the holiday remain unclear. Nonetheless, Chaucer's mention is one of the earliest known associations with the date.
