Question

Why is 82⅟₂° E longitude chosen as the standard meridian for India?

Answer 1

India has a vast longitudinal stretch, and the local time calculated at every meridian is different. Since this might lead to confusion regarding the time, a standard meridian was chosen to calculate the time of the whole country. 82⅟2°E longitude was chosen because it lies almost in the centre of India. The standard meridian is also necessary for commercial, travel and logistical purposes within the country.
