he National Flag of India was adopted in its present form during an ad hoc meeting of the Constituent Assembly held on the 22 July 1947, twenty-four days before India's independence from the British on 15 August 1947. It has served as the national flag of the Dominion of India between 15 August 1947 and 26 January 1950 and that of the Republic of India thereafter.[3] In India, the term "tricolour" (Hindi: तिरंगा, Tirangā) almost always refers to the Indian national flag.
The national flag, adopted in 1947, is based on the flag of the Indian National Congress, designed by Pingali Venkayya. The flag is a horizontal tricolour of "deep saffron" at the top, white in the middle, and green at the bottom. In the centre, there is a navy blue wheel with twenty-four spokes, known as the Ashoka Chakra, taken from the Lion Capital of Asoka erected atop Ashoka pillar at Sarnath. The diameter of this Chakra is three-fourths of the height of the white strip. The ratio of the width of the flag to its length is 2:3.[4] The flag is also the Indian Army's war flag, hoisted daily on military installations.
The official flag specifications require that the flag be made only of khadi, a special type of hand-spun cloth made popular by Mahatma Gandhi; while these specifications are widely respected within India, they are frequently ignored in the manufacture of Indian flags outside of the country. The display and use of the flag are strictly regulated by the Indian Flag Code.[4] A heraldic description of the flag would be Party per fess Saffron and Vert on a fess Argent a "Chakra" Azure.
