April Fools' Day, observed each year on April 1st, is a time for playing pranks and telling jokes. A key tradition of the day is that all jesting must conclude by 12pm (midday). Those who persist with pranks into the afternoon are considered to be the 'April Fools' themselves, as it is seen as bad luck to continue after the specified time, according to the British Council.
Historical Roots of the Tradition
The practice of stopping pranks at midday may date back to 1851. A passage in a British journal from that year reportedly stated that anyone playing a trick after noon should be told, "April Fools' gone past, You're the biggest fool at last," as reported by the BBC. This suggests a long-standing convention regarding the timing of such observances.

Theories on Origin
The exact origins of April Fools' Day are not definitively known, with several theories proposed. One perspective, explained by the BBC, links the tradition to calendar events and the start of new seasons. In Roman times, 'renewal festivals' were celebrated to mark the beginning of a new year or season, during which normal life was suspended, potentially influencing the chaotic nature of April Fools' pranks.
Another theory connects the date to the shifting of the calendar, particularly around the spring equinox. Historically, the start of spring, when planting could begin, was considered the new year. When the new year was officially moved to January, those who continued to observe it in late March might have been subjected to jokes and pranks, thus contributing to the tradition of the 'April Fool'.
