International Waffle Day was started in Sweden where it is known as Våffeldagen. It is annually held on March 25.
The Annunciation of the Virgin Mary was once called "Vårfrudagen" (Our Lady's Day) in Swedish. In certain dialects, the word "Vårfrudagen" was pronounced as "Våfferdagen" [1], Over time the word became "Våffeldagen" (Waffle Day), giving rise to the tradition of eating waffles on this day.
Chris Matthewson, mayor of Waltz, Michigan, declared "International Waffle Day" an official holiday of the small village in March of 2006.
