Question

why 82 degree 30 minute East has been selected as the Standard Meridian of India

Answer 1

The Earth has been divided into 24 time zones of one hour each. Each of these zones covers 15 degrees of longitude.

As the local time differs by 4 minutes at every longitude, it would create a lot of confusion regarding time for any country as a whole which may stretch across several longitudes.

Therefore each country selects a central meridian and the local time of this meridian is the standard time of that country.

The local times which lie on different meridians are bound to differ.

The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat.
