World Hello Day

World Hello Day is celebrated every year on November 21 around the world. This friendly holiday encourages people to open their hearts and spread cheer. To participate, simply say “hello” to your neighbor, and maybe add “have a nice day.”

History

World Hello Day was established in 1973 by two brothers from Arizona, Brian and Michael McCormack. Inspired by the military conflict between a coalition of Arab countries and Israel, they decided to send letters to leaders of various nations to encourage peaceful communication. In the first year, they gained support from 15 countries, and over time, 165 countries joined the campaign. Today, World Hello Day is recognized by both ordinary people and world leaders.
