Though various cities may have their own Tartan Day, April 6th is the National Tartan Day in America and in Scotland. This day celebrates Scottish heritage and also its independence.
The tartan originated in Scotland and became associated with a particular region, district, family or regiment. The weave is a pattern of threads repeated in both breadth and width, thus the pattern is the same when you turn it 90 degrees.
The tartan is such a part of Scottish identity that the English government banned the wearing of it after the Scottish rebellion of 1746 until 1782. The tartan was considered a uniform of rebels.
Many ancient civilizations had bagpipes, but who does not think of Scotland when they hear the call of the pipers.
If you do not like the sound of the bagpipes DO NOT GO NEAR THAT DIAL!
