With a record 175 countries as co-sponsors, the UN General Assembly adopted a resolution for the observance of International of Yoga on June 21 each year. The UN does not incur any budgetary expense as the day would be observed by private sponsors and events. The Indian prime minister, Narendra Modi, had proposed holding an international yoga day in his September 27 speech to the UN General Assembly in New York. June 21st is the summer solstice (equal day and night) and has many significances. The day presents balance in yoga.
