Hello readers! Did you guys know that November 21 is celebrated as World Hello Day? A word that is so commonly used has a day of its own! But the story of how the day came into existence is quite touching. Hello Day was first created in 1973 to pass the message that conflicts can be resolved through communication. The day is for world leaders to settle their conflicts with communication and to not resort to conflicts.

The annual global day was first observed in 1973 as a response to the Yom Kippur War between Israel and a coalition of Arab states led by Egypt and Syria in 1973. Brian McCormack, a PhD graduate of Arizona State University, and Michael McCormack, a graduate of Harvard University, mailed 1360 letters, in seven languages, to government leaders worldwide. This Salman Khan ‘Hello, Hello’ Song Is Perfect Way to Celebrate World Hello Day (Watch Video)
