Tartan Day is observed on April 06, 2023. Tartan Day is a celebration of Scottish heritage on April 6, the date on which the Declaration of Arbroath was signed in 1320. An ad hoc event was held in New York City in 1982, but the current format originated in Canada in the mid 1980s. It spread to other communities of the Scottish diaspora in the 1990s. In Australasia the similar International Tartan Day is held on July 1, the anniversary of the repeal of the 1747 Act of Proscription that banned the wearing of tartan. Tartan Days typically have parades of pipe bands, Highland dancing and other Scottish-themed events.
In the United States it is estimated that there are 6 million people who claim Scottish descent. Little was done to follow up the New York event in 1982. In 1998, a Coalition of Scottish Americans with the Support of Senator Trent Lott, successfully lobbied the Senate for the designation of April 6 as National Tartan Day "to recognize the outstanding achievements and contributions made by Scottish Americans to the United States".
Outside New York City, one of the largest Tartan Day celebrations in the United States takes place each year on the weekend closest to April 6 on the banks of the Missouri river in St. Charles, Missouri. In addition to the above celebrations, the Washington, DC, and Baltimore, Maryland, Scottish-American Societies hold Tartan Day Celebrations. (With material from: Wikipedia)
