The origins of April Fools' Day are shrouded in mystery, experts say.

The most popular theory is that France changed its calendar in the 1500s so that the New Year would begin in January to match the Roman calendar instead of the start of spring in late March or early April.

However word of the change traveled slowly, and many people in rural areas continued to celebrate the New Year in the spring. These country dwellers became known as "April fools."

Boese, who has studied the holiday's origin, disagrees with that interpretation.

"[The French] theory is completely wrong, because the day that the French celebrated the beginning of the year legally was Easter day, so it never really was associated with April first," he said.

"Traditionally it was only a legal start to the year—people in France did actually celebrate [the New Year] on January first for as long as anybody could remember."
