November 20 brings some noteworthy anniversaries. Perhaps the biggest is the 67th wedding anniversary of Queen Elizabeth. See the others:

185 years ago a giant sperm whale attacked a whaling ship, later inspiring "Moby Dick"!
71 years ago the Nuremberg Trials started.
52 years ago the Cuban missile crisis ended.
29 years ago Microsoft Windows 1.0 was released
6 years ago the Dow Jones Industrial Average dropped to its lowest in over a decade due to the financial crisis.

Weighing all the anniversaries in recorded history, Nov. 20 appears to have been somewhat cursed with bad news. So if you're having a lousy day IT'S NOT YOUR FAULT! If you're absolutely killing it today, you're doing your small part to change history!
