Recurrence pattern: every year on November 26.

National Milk Day is observed in India every November 26 to commemorate the birthday of Verghese Kurien, known as the “Father of the White Revolution.” Established in 2014, this day honors Kurien's significant contributions to the dairy industry, particularly through the development of the cooperative model that linked milk producers directly with consumers, thereby eliminating middlemen. Kurien's efforts led to the launch of Operation Flood in 1970, which transformed India into the world's largest milk producer. The day is marked by various celebrations organized by major dairy producers and the Indian Dairy Association, highlighting the importance of milk in Indian culture and economy. Verghese Kurien's legacy continues to influence the dairy sector, where the majority of milk produced comes from buffalo.
