Languages with official status in India
Even though the English language is not included in the Eighth Schedule (as it is a foreign language), it is one of the official languages of the Union of India.
Of the 22 official languages, 15 are Indic, four are Dravidian, two are Tibeto-Burman, and one is Munda.
Languages of India
The Indian constitution, in 1950, declared Hindi in Devanagari script to be the official language of the union. Unless Parliament decided otherwise, the use of English for official purposes was to cease 15 years after the constitution came into effect, i.e. on 26 January 1965. The prospect of the changeover, however, led to much alarm in the non Hindi-speaking areas of India, especially in South India whose native tongues are not related to Hindi. As a result, Parliament enacted the Official Languages Act in 1963, which provided for the continued use of English for official purposes along with Hindi, even after 1965.
