International Caps Lock Day

International Caps Lock Day is an interesting holiday celebrated around the world on October 22nd. This holiday serves to remind people that it is impolite to write in all caps. Everyone knows that the Caps Lock key capitalizes letters, but if messages arrive with just such letters, it can give the impression that the sender is shouting or expressing dissatisfaction.


International Caps Lock Day was founded in 2000 by Derek Arnold. As many other internet users, he had encountered the annoying communication style of typing in all caps. He wanted to ridicule those who use the function unnecessarily, and bring order to online communication. Typewriters, the forerunners of computers, only printed in capital letters. In 1870, Remington revolutionized the way people type by introducing upper and lower case letters and the Shift key.

Interesting facts
