National Unity Day (Hindi: राष्ट्रीय एकता दिवस, romanized: Rāshtrīya Ektā Divas) is celebrated in India on 31 October. It was introduced by the Government of India in 2014. The day is celebrated to mark the birth anniversary of Vallabhbhai Patel who had a major role in the political integration of India.^[1][2]

The official statement for National Unity Day by the Home Ministry of India cites that the National Unity Day "will provide an opportunity to re-affirm the inherent strength and resilience of our nation to withstand the actual and potential threats to the unity, integrity, and security of our country."^[3]

On the day, a pledge is read out in government offices:^[1]

I solemnly pledge that I dedicate myself to preserving the unity, integrity, and security of the nation and also strive hard to spread this message among my fellow countrymen. I take this pledge in the spirit of the unification of my country which was made possible by the vision and actions of Sardar Vallabhbhai Patel. I also solemnly resolve to make my own contribution to ensure the internal security of my country.

31 October is also celebrated as Rashtriya Sankalp Diwas or National Pledge Day as it marks the day of assassination of Indira Gandhi.^[4] Several schools and colleges, especially in Congress-run states, organize rallies and programmes in remembrance of Indira Gandhi.
