5/11
Guy Fawkes Night in the UK, celebrating the Gunpowder Plot of 5th November 1605, when religious fundamentalists were thwarted in their attempted terrorist attack against the Houses of Parliament in the United Kingdom. A proposed new name for these celebrations in line with the modern tradition of referring to significant events using just numbers (although in the UK the day comes before the month).
