First off, can we commonize the spelling? I'm going with the 'Mericans on this one. Let's get rid of the U. Bilingualism is bad enough. This is just a pain in the ass. For now, being true to my nationality, the U remains.
Anyway, In Canada and the United States, Labor Day is a federal holiday observed on the first Monday of September. It is customarily viewed as the end of the summer vacation season and many schools open for the year on the day after Labour Day. Kind of sad to say goodbye to summer, but winter is going to happen no matter what, so fuckit! We get a day off!
An old fashioned weird tradition in Canada and the United States frowns upon the wearing of white after Labour Day. Explanations for this tradition vary; the most common is that white is a summer colour and Labour Day unofficially marks the end of summer. The rule may have been intended as a status symbol for new members of the upper and middle classes in the late 19th and early 20th century. Other explanations note that this tradition may have been created as a prevention measure in snow ravaged areas. Many deaths in the late 19th and early 20th century period were attributed to rescue teams being unable to locate those that had become lost in snowy regions as they were wearing only white. That's just fucked up!
In the new world, you will be permitted to wear any color you like after Labour / Labor day day.
AND SO IT SHALL BE WRITTEN!
