indian standard time zone passes through which states in india
Indian Standard Time Indian Standard Time (IST) is the time observed throughout India, with a time offset of UTC+05:30. India does not observe daylight saving time (DSTu) or other seasonal adjustments. In military and aviation time IST is designated E* ("Echo-Star").[1]
Indian Standard Time After independence in 1947, the Indian government established IST as the official time for the whole country, although Kolkata and Mumbai retained their own local time (known as Calcutta Time and Bombay Time) until 1948 and 1955, respectively.[3] The Central observatory was moved from Chennai to a location at Shankargarh Fort Allahabad district, so that it would be as close to UTC +5:30 as possible.
Time in Indiana Since April 2, 2006, all counties in Indiana observe daylight saving time.
Indian national calendar Usage started officially at 1 Chaitra 1879, Saka Era, or 22 March 1957. However, government officials seem to largely ignore the New Year's Day of this calendar in favour of the religious calendar.[3]
