Question

why 82°30'E has been selected as the standard meridian of india?​

Answer 1

Answer By Amit

From Gujarat to Arunachal Pradesh there is a time lag of two hours. Hence, time along the Standard Meridian of India (82° 30' E) passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for the whole country. Otherwise different regions of India would have different times which would create problems; so, to have one common standard times for the whole country has been selected and called Indian Standard Time (IST).
