May 4 – Anti-Bullying Day
Anti-Bullying Day is a day when people wear mainly a pink shirt to symbolise a stand against bullying, an idea that originated in Canada. It is celebrated on various dates around the world. In 2012, the United Nations declared the official day to be May 4, some countries prefer to celebrate it on 28/29 February, which was recognised by many countries worldwide, including Australia, New Zealand, France, Lebanon, the United Kingdom and the United States. It is celebrated on February 27th in Canada, but International Day of Pink is also celebrated there, on a different day.
