November 21, 2011 is the 39th annual World Hello Day. Anyone can participate in World Hello Day simply by greeting ten people. This demonstrates the importance of personal communication for preserving peace.
World Hello Day was begun 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.
As a global event World Hello Day joins local participation in a global expression of peace. The World Hello Day web site address is http://www.worldhelloday.org.
31 winners of the Nobel Peace Prize are among the people who have realized 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.
Brian McCormack, a Ph.D. graduate of Arizona State University, and Michael McCormack, a graduate of Harvard University, work together to promote this annual global event. - source: http://www.worldhelloday.org/
