The unofficial holiday was created by Brian and Michael McCormack as a response to the Yom Kippur War between Israel and a coalition of Arab states led by Egypt and Syria in 1973.

Say Hello

The purpose of World Hello Day is simple – to encourage communication and dialogue between people of different backgrounds in order to achieve peace and understanding.

Since its beginning in 1973, the day has been celebrated around the world annually with several Nobel Peace Prize winners and peace activists taking part in it.

How to Celebrate?

  • World Hello Day requires that participants greet at least 10 people. These people can be family and friends, but it is suggested that one finds strangers to greet and talk to.

Did You Know…

…that hello was used as a telephone greeting for the first time by Thomas Edison?
