The History of National When Pigs Fly Day

The phrase at the heart of the day is centuries old. “When pigs fly” is an example of an adynaton, a figure of speech that exaggerates to the point of implying impossibility. The expression is thought to derive from a Scottish proverb dating to the 1500s, and an early version, “pigs fly with their tails forward,” appeared in John Withals’ 1616 work A Shorte Dictionarie for Yonge Begynners. Flying pigs cropped up in British print throughout the 19th century, and the image even features in Lewis Carroll’s Alice’s Adventures in Wonderland.

The awareness day itself is far more recent. National When Pigs Fly Day was first celebrated on 9 September 2020, founded by Lisa J. Schanley.
