World Water Day

International World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources. ... The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day.

On 22 March every year World Water Day is celebrated around the world to create the awareness about the importance of water and its conservation.
