World Hello Day – November 21, 2024

World Hello Day is a secular unofficial holiday celebrated on November 21 by 180 countries to illustrate the importance of personal communication for preserving peace. On this day, people are encouraged to participate by simply greeting 10 people. Winners of the Nobel Peace Prize are among the people who have noted World Hello Day’s value as an instrument for preserving peace and as an occasion that makes it possible for anyone in the world to contribute to the process of creating peace. Other supporters include almost 100 authors, entertainers, and world leaders. Remember to greet someone kindly on this day!

History of World Hello Day

World Hello Day was originally created in 1973 by Arizona State University graduate Brian McCormack and Harvard graduate Michael McCormack as a direct response to the Arab-Israeli war officially known as the Yom Kippur War. 

Gathering all the money they had at the time, these two brothers bought postage and sent out letters to as many world leaders as they could and asked them to support this new holiday. Within the first 12 months of their campaign, they received the support of over fifteen different countries. In the last 42 years, they have managed to gather the support of an additional one hundred and sixty-five countries.

Today, this day is used by ordinary people – as well as world leaders – from all around the world to settle their differences with communication rather than conflict. The McCormack brothers have also received strong support for their holiday from writers, entertainers and Nobel Laureates from all over the globe.

The only real custom associated with World Hello Day is the practice of saying ‘hello’ to friends, families and strangers. People who want to celebrate this holiday should take the time to say hello to at least 10 people they encounter throughout the day – particularly strangers. People should also take the time to learn how to say hello in a couple of different languages and then put that into practice sometime during the day.

World Hello Day is an opportunity for everyone, all throughout the globe, to make an effort at reaching out to one another, taking steps towards world peace. The primary means to achieving this personal connection is by simply saying, ‘hello!”
