11-11-11...isn't that the end of World War I and its date and time? The eleventh day, at the eleventh hour of the eleventh month? Armistice Day? In the USA, President Eisenhower declared this to be "Veteran's Day", way back in 1954.
You Germans know how to throw a party!
On November 11, at exactly 11:11 pm, the Carnival season begins!
The reason for this date is at the number 11, which is traditionally regarded as the number of fools and madmen.
The carnival took place every year just before the start of Lent, the forty days before Easter in which Christians were allowed to eat meat.
Possibly the name comes from the Latin expression carne vale, that means "farewell to the flesh"
From Italy, the Carnival hit over into neighboring countries and gradually spread to the rest of Europe.
The start of the carnival season, in almost every Carnival celebrating city / town in Europe, is done with a certain ceremony.
Carnival has already emerged in the 10th century and this tradition is celebrated throughout Europe,
including Netherlands, Belgium, Germany, Switzerland, Austria, Italy, Spain, France...
I can ensure you, not only in Germany people know how to celebrate Carnival!
Carnival has actually nothing to do with World War I or your Veteran's Day.
