Question

Why 82°30'E is selected as standard meridian?

Answer 1

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 time for whole country, this has been selected and called indian standard time(IST).
