The International Day of Yoga has been celebrated annually on 21 June since 2015, following its inception in the United Nations General Assembly in 2014. Yoga is a physical, mental, and spiritual practice that originated in India. The Indian Prime Minister, Narendra Modi, in his UN address in 2014, had suggested the date of 21 June, as it is the longest day of the year in the Northern Hemisphere and shares a special significance in many parts of the world.
The idea of an International Day of Yoga was first proposed by the current Prime Minister of India, Narendra Modi, during his speech at the United Nations General Assembly (UNGA), on 27 September 2014. He stated:
Yoga is an invaluable gift of India's ancient tradition. It embodies unity of mind and body; thought and action; restraint and fulfillment; harmony between man and nature; a holistic approach to health and well-being. It is not about exercise but to discover a sense of oneness with yourself, the world, and nature. Changing our lifestyle and creating consciousness, can help in well-being. Let us work towards adopting an International Yoga Day.
Following this initial proposal, the UN adopted the draft resolution, entitled "Day of Yoga", in 2014. The consultations were convened by the delegation of India. In 2015 Reserve Bank of India issued a 10 rupees commemorative coin to mark the International Day of Yoga. In April 2017, UN Postal Administration (UNPA) issued 10 stamps on Asanas on a single sheet to mark the International Day of Yoga.
