Sherpa Tenzing Norgay and Edmund Hillary were the first mountaineers to reach the summit of Mount Everest on May 29, 1953.
International Mount Everest Day, first celebrated in 2008, commemorates their achievement and is held on May 29.
Mount Everest is known as 'Sagarmatha' in Sanskrit and Nepali, and 'Chomolungma' or 'Mother Goddess of the World' in Tibetan.
The mountain was renamed in honor of George Everest, a former Surveyor General of India, in 1865.
Tenzing Norgay participated in six Everest expeditions before successfully reaching the summit.
Norgay received numerous international honors including the George Medal, Order of the Star of Nepal, and Padma Bhushan, and a peak was named after him in 2013.
