National Sports Day in India is celebrated on:

Many countries mark a National Sports Day to honour a landmark figure or achievement in their sporting history, typically anchoring the date to that person's birth anniversary, and using the occasion to promote athletic excellence and physical fitness nationwide.

In India, 29 August has been nationally celebrated as National Sports Day since 2012, marking the birth anniversary of hockey legend Major Dhyan Chand (born 29 August 1905), whose extraordinary skill helped India win three Olympic hockey gold medals. The date is also linked with India's top sporting honours — the Khel Ratna, Arjuna, and Dronacharya awards — customarily conferred around this occasion.

• 25 August carries no government-designated sporting commemoration in India.

• 30 August is likewise not linked to any official sports anniversary or landmark event.

• 31 August similarly has no attached national sporting observance.

Hence, National Sports Day in India is celebrated on 29 August.
