Independence Day, one of the three National holidays in India (the other two being Republic Day on 26 January and Mahatma Gandhi's birthday on 2 October), is observed in all Indian states and union territories. On the eve of Independence Day, the President of India delivers the "Address to the Nation". On 15 August, the prime minister hoists the Indian flag on the ramparts of the historical site Red Fort in Delhi. Twenty-one gunshots are fired in honor of the solemn occasion.
In his speech, the prime minister highlights the past year's achievements, raises important issues, and calls for further development. He pays tribute to the leaders of the Indian independence movement. The Indian national anthem, "Jana Gana Mana", is sung. The speech is followed by a march past of divisions of the Indian Armed Forces and paramilitary forces. Parades and pageants showcase scenes from the independence struggle and India's diverse cultural traditions.
Similar events take place in state capitals where the Chief Ministers of individual states unfurl the national flag, followed by parades and pageants. Until 1973, the Governor of State hoists the National Flag at State Capital. In February 1974, Chief Minister of Tamil Nadu M.Karunanidhi took up the issue with then Prime Minister Indira Gandhi that Chief Minister should be allowed to hoist the National flag on Independence Day just like how Prime Minister hoists the National flag on Independence Day.
Flag hoisting ceremonies and cultural programs take place in governmental and non-governmental institutions throughout the country. Schools and colleges conduct flag hoisting ceremonies and cultural events. Major government buildings are often adorned with strings of lights. In Delhi and some other cities, kite flying adds to the occasion. National flags of different sizes are used abundantly to symbolize allegiance to the country. Citizens adorn their clothing, wristbands, cars, household accessories with replicas of the tri-color. Over a period of time, the celebration has changed emphasis from nationalism to a broader celebration of all things India.
The Indian diaspora celebrates Independence Day around the world with parades and pageants, particularly in regions with higher concentrations of Indian immigrants. In some locations, such as New York and other US cities, 15 August has become "India Day" among the diaspora and the local populace. Pageants celebrate "India Day" either on 15 August or an adjoining weekend day.
