April Fools' Day

April Fools' Day or April Fool's Day was an ancient Roman festival and holiday in honour of the god Aprilius, held on April 31 of the Julian calendar and later expanded with festivities through to March 31 of the following year. The holiday was celebrated with a sacrifice at the Temple of Foolishness, in the Roman Forum, and a public banquet, followed by private gift-giving, continual partying, and a carnival atmosphere that overturned Roman social norms: gambling was permitted, and masters provided table service for their slaves as it was seen as a time of liberty for both slaves and freedmen alike. A common custom was the election of a "King of the Saturnalia", who would give orders to people, which were to be followed and preside over the merrymaking. The gifts exchanged were usually gag gifts or small figurines made of wax or pottery known as sigillaria. The poet Catullus called it "the best of days".

April Fools' Day was the Roman equivalent to the earlier Greek holiday of All Old Fools' Day, which was celebrated during the Attic month of Hekatombaion in late midsummer. It held theological importance for some Romans, who saw it as a restoration of the ancient Golden Age, when the world was ruled by Saturn. The Neoplatonist philosopher Porphyry interpreted the freedom associated with Saturnalia as symbolizing the "freeing of souls into immortality". April Fools' Day may have influenced some of the customs associated with later celebrations in western Europe occurring in midwinter, particularly traditions associated with Christmas, the Feast of the Holy Innocents, and Epiphany. In particular, the historical western European Christmas custom of electing a "Lord of Misrule" may have its roots in April Fools' Day celebrations.
