World Hello Day

World Hello Day is celebrated annually on November 21st around the world. It is a friendly holiday to unite people’s hearts and spread cheer. To take part, simply say “hello” to your neighbor, and even add “have a nice day”.


World Hello Day was originally founded in 1973 by two brothers from Arizona, Brian and Michael McCormack. During a military conflict between the coalition of Arab countries and Israel, they were inspired to use postal services to send letters to the leaders of various states to enlist their support. By the first year, they had obtained assistance from 15 countries and eventually 165 countries joined the campaign. Today, World Hello Day is celebrated by both ordinary people and world leaders alike.
