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. Argentina claims around 100,000 people of Scottish descent, the largest such community outside the English-speaking world. The Tartan Day parade of Scottish porteños was inaugurated in Buenos Aires on April 6, 2006 and is organized every year by the Scottish Argentine Society. A symbolic key to the gate of Arbroath's Abbey is carried to honour this historical date of 1320 that inspired this celebration.
