Quick quiz, folks.
Who can tell me what happened on October 10, 1582 in Rome?
Hint #1: Shakespeare and Cervantes died on the same day. Though it was obviously not this day.
Update: Congratulations to all of you who got it right, and complete boo to those of you who did not. It turns out that Oct. 10, 1582 did not exist, along with about 10 other days. This was caused by a switch from the Julian Calendar to the Gregorian one. Because of this, certain areas of the world went from Thursday, October 4 directly to Friday, October 15.
The crazy thing is that this didn't happen everywhere. England, for example, did not recognize this switch. This means that, though both Shakespeare (who lived in England) and Cervantes (who lived in Spain) died on April 23, 1616, one actually died about 10 days earlier!
