How Else is the Number Thirteen Considered Unlucky and What Does Devil’s Luck Mean?

Friday the thirteenth is considered unlucky, but the superstition also applies to apartments.

80 percent of apartments don’t have a thirteenth floor.

Airplanes have no thirteenth aisle, and hospitals and hotels have no room number thirteen.

The most bizarre superstition is called the Devil’s luck, for those with thirteen letters in their names, including Jack the Ripper, Charles Manson, Jeffrey Dahmer, Theodore Bundy, and Albert De Salvo.
