According to Wikipedia the International Day of Peace (known unofficially as World Peace Day) is held on 21 september. It is dedicated to world peace, and specifically the absence of war and violence. The day was first celebrated in 1982, and it is kept by many nations, political groups and people.
For my video, I have chosen a poem written by Md Khairul Islam, because I totally agree with him when he states that "war never mean peace".
