Why 21 June was chosen as International Yoga Day?
United Nations has passed a resolution declaring June 21 every year as the International Yoga Day (World Yoga Day). India’s Prime Minister Narendra Modi had urged the International Community to adopt 21 June as the International Yoga Day.
Every year in Northern hemisphere, the Summer Solstice falls on June 21. It is the day when Day is longest and the night is shortest. It is the day when Earth is at its closest distance from the Sun on its orbit.
From the perspective of yoga, the Summer Solstice marks the transition of Sun from Uttarayana to Dakshinayana, according to ancient Vedic Calendar. According to Vedic Books, it was the day when Lord Shiva, first taught Yoga to his disciples. The knowledge of Yoga first descended from Shiva on this day. We can say, June 21 as the Birthday of Yoga. This is the reason why several Yogic Preachers had advocated celebrating June 21 as the International Yoga Day.
