I know I’m a fool . . .
This is the day upon which we are reminded of what we are
on the other three hundred and sixty-four.
~Mark Twain, Pudd’nhead Wilson, 1894
The origins of April Fools’ Day are murky, but the likeliest explanation is that it began as a way to mock French people who were slow to switch to the Gregorian Calendar which changed New Year’s from April 1 to January 1. These folks were labeled “fools” and some were sent on “fools’ errands.”
