Indian Republic Day is observed on January 26, 2023. In India, Republic Day honours the date on which the Constitution of India came into force - on 26 January 1950 - replacing the Government of India Act (1935) as the governing document of India.
It is one of three national holidays in India. The new constitution, as drafted and approved by the Constituent Assembly of India, was mandated to take effect on 26 January 1950–and India became a republic. While India's Independence Day celebrates its freedom from British Rule, Republic Day celebrates the coming into force of its constitution.
The main Republic Day celebration is held in the national capital, New Delhi, at the Rajpath before the President of India. Celebrations are also held with varying degrees of formality in state capitals, where the governor of the state unfurls the National Flag of India. (With material from: Wikipedia)
