World Kindness Day is celebrated annually on 13th November. On this day, participants attempt to make the world a better place by celebrating and promoting good deeds and pledging acts of kindness, either as individuals or as organizations.
World Kindness Day was first launched in 1998 by The World Kindness Movement, an organisation formed at a 1997 Tokyo conference of like-minded kindness organisations from around the world. There are currently over 28 nations involved in The World Kindness Movement which is not affiliated with any religion or political movement. The mission of the World Kindness Movement and World Kindness Day is to create a kinder world by inspiring individuals and nations towards greater kindness.
