Seventy years ago, India first adopted Indian Standard Time (IST) #OnThisDay in 1947. Time zones were officially established in India in 1884, during the British rule. Two time zones - Bombay Time and Calcutta Time, were used - due to the importance of these cities as commercial and economic centres. Today India’s time zone is calculated according to the longitude of 82.5° E. at Shankargarh Fort in Mirzapur (Allahabad, Uttar Pradesh) as the central meridian for India. With a time offset of UTC+5:30, India is five and a half hours ahead of Greenwich Mean Time.
