“It’s April Fools’ Day,” would likely be your defense, unless you do this sort of thing all the time. If you don’t, and it’s a seasonal thing, we get you.

What is it about the first day of April that brings out the prankster, or the fool (you know who you are) in us?

Here’s a quick look at the history, the mystery and the madness of April Fools’ Day.

The History

This is the short explanation – no one knows when or why April Fools’ Day was created. Theories as to the origin of the day of pranking range from holidays celebrated by the Romans and Hindus, -- the new year started for them around April 1 – to a riff on the Feast of the Annunciation or the vernal equinox.

Where does the “fool” part come in?

Again, the history is fuzzy on this, but in 1582 a new calendar was introduced by Pope Gregory XIII that moved the first day of the new year to Jan. 1. The 1580s being what they were, news traveled a bit slow and some didn’t get the memo, so they continued to celebrate new year’s on April 1. The hipper, more calendar-wise set mocked these people, and often sent them on “fool’s errands.”

That explanation could, itself, be an April Fool’s joke, according to some.

Another theory holds that the day is tied to Hilaria, a Roman festival that saw people dressing in costume to celebrate the resurrection of the Roman God Attis. The festival was also known as Roman Laughing Day.
