Chaliyar Day is celebrated on January 11, marking both the formation of Chaliyar Doha and the remembrance of K.A. Rahman Sahib, a prominent activist who led the historic Chaliyar River protection movement in Kerala. Inspired by his legacy, Chaliyar Doha was officially formed on this day in 2015.

In the founding year itself, Chaliyar Doha organised a major discussion forum attended by Presidents of several Grama Panchayaths situated along the Chaliyar River, representatives of the Collectors of Malappuram and Kozhikode, as well as MLAs and MPs. The discussions focused on river conservation, reducing pollution, maintaining river cleanliness, and identifying practical approaches to protect and preserve the Chaliyar River. Chaliyar Day continues to highlight the organisation’s environmental roots and deep commitment to sustainability and ecological awareness.
