      Why 82°30' E has been as the standard meridian of India?

    Answer:

                      82°30'E meridian has been selected as the standard meridian of India for the following reasons: (i) This is a general understanding among the countries of the world to select a Standard Meridian in multiples of 7°30' east and west of Prime Meridian. It is equal to half an hour. (ii) A country's standard time is derived from such a central meridian. The minimum difference of time between two consecutive standard meridians should be half an hour. (iii) 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 (U.P.) is taken as the standard time for the whole country.
