Why 82°30′ E is selected as Standard Meridian of India?
82°30′ E is selected as Standard Meridian of India because:
→ It almost passes through the center of the country.
→ It is exactly 5 hours 30 minutes ahead of GMT.
→ It is multiple of 7°30′ as a globe has 24 time zones, each of 15 longitudes so local time in each zone at the middle longitude (divided by 7°30') is taken as Standard Time.
