International Day of Non-Violence is observed on October 02, 2021. The International Day of Non-Violence is observed on the birthday of Mohandas Gandhi. This day is referred to in India as Gandhi Jayanti. In 2004, Iranian Nobel laureate Shirin Ebadi had taken a proposal for an International Day of Non-Violence from a Hindi teacher in Paris teaching international students to the World Social Forum in Bombay.
The idea gradually attracted the interest of some leaders of India's Congress Party until a Satyagraha Conference resolution in New Delhi in January 2007 initiated by Sonia Gandhi and Archbishop Desmond Tutu called upon the United Nations to adopt the idea. On 15 June 2007 the United Nations General Assembly voted to establish 2 October as the International Day of Non-Violence.
The resolution by the General Assembly asks all members of the UN system to commemorate 2 October in "an appropriate manner and disseminate the message of non-violence, including through education and public awareness." (With material from: Wikipedia)
