October 22 IS CAPS LOCK DAY! The day celebrates the Caps Lock on a computer keyboard and was created by Derek Arnold in 2000.

It is unclear what the exact purpose of this made-up holiday is. Perhaps it encourages people to use the Caps Lock in their online communications. Or maybe it discourages them to use it because using all caps in an electronic communication is generally associated with anger and yelling.


On most keyboards, caps lock is a button or key that when set forces all types letters to be in uppercase. The mode can be switched off by pressing the caps lock key again.

Caps Lock Day is also called International Caps Lock Day and is sometimes celebrated on June 28.
