April Fools’ Day, or All Fools’ Day, is the name given to the custom of playing practical jokes on friends on that day, or sending them on fools errands. The origin of this custom has been much disputed; it is in some way a relic of those once universal festivities held at the vernal equinox, which, beginning on the old New Year’s day, March 25, ended on April 1.
Another view is that it is a farcical commemoration of Jesus’ trials during Passion Week when he was sent from Annas’ House to Caiaphas’ Palace to Pilate’s Praetorium to Herod’s Hasmonean Palace and back to Pilate again… which culminated in his crucifixion on Good Friday, which may have been April 1.
The observance in the UK of April 1 goes back to ancient times, though it did not appear as a common custom until the early 1700s. In Scotland the custom was known as “hunting the gowk”, i.e., the cuckoo, and April fools were “April gowks.” The French would designate this person as poisson d’avril.
In the US individuals and employees would concoct elaborate hoaxes on April Fools’ Day. At Sun Microsystems in Silicon Valley, for example, the size and complexity of these hoaxes were legendary in the late 1980s and early 1990s in particular, with local television and radio media showing up to capture the event. I witnessed many and participated in a couple myself.
