When hypothesis are confirmed by varied tests then it becomes theory. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable.

The International Day of Yoga is celebrated on June 21st each year. This day was officially designated by the United Nations in 2014 to promote the numerous benefits of yoga and encourage people around the world to incorporate yoga into their daily lives. June 21st was chosen as the International Yoga Day because it corresponds to the summer solstice in the Northern Hemisphere, which has special significance in many cultures. The day aims to raise awareness about the physical, mental, and spiritual benefits of practicing yoga.
