25 July 1977

The 15th President of India Draupadi Murmu took the oath on July 25, the date which is being followed by many presidents in the past four-decades. Notably, since 1977, every President of India has taken the presidential oath on July 25, as they ended their full five-years term, usually ended on July 24. India's-sixth-President Neelam Sanjiva Reddy was the first to be sworn in on July 25, which became tradition.
