The International Tartan Day is observed on 1st July on the anniversary of the repeal of Act of Proscription (1747) that banned the prohibited the wearing of tartan.
The day was declared by Governor Hugh Carey and New York City Mayor Ed Koch in 1982.
Tartan day is celebrated in Australasia with Scottish-themed parades and events. Bagpipes and Highland dancing are popular highlights on the day.
There is another Tartan Day, probably the more popular of the two, which is observed on the 6th of April. The Declaration of Arbroath was signed on that date in 1320.
