July 22 Holidays

Mango Day celebrates the tropical stone fruit that dominates global production at more than 50 million metric tons annually — India produces approximately 40 percent of the world’s mangoes — and whose flavor ranges from floral and sweet to tart and resinous depending on variety. National Hammock Day celebrates the woven or fabric bed suspended between two anchor points — invented by the Taíno people of the Caribbean and brought to Europe by Columbus’s sailors, who observed its utility for sleeping above vermin on ships. National Rat Catcher’s Day marks July 22, 1376, the date associated with the Pied Piper of Hamelin legend, in which a rat-catcher lured children away from the town after the townspeople refused to pay him. Casual Pi Day celebrates the fraction 22/7 — a common approximation of π — with the date 7/22 matching the numerator and denominator in European date format. A mango, a hammock, a piping legend, and a mathematical approximation.
