World Hello Day is celebrated on November 21st of each year. It began in response to the conflict between Egypt and Israel in the Fall of 1973. Since then, World Hello Day has been observed by people in 180 countries.
People around the world use the occasion of World Hello Day as an opportunity to express their concern for world peace. Beginning with a simple greeting on World Hello Day, their activities send a message to leaders, encouraging them to use communication rather than force to settle conflicts. The goal of World Hello Day is for each person to greet at least 10 people with a simple hello. This demonstrates the importance of personal communication for preserving peace. (World Hello Day)
