Latitudinal and Longitudinal Extent
India's mainland extends between 8°4'N and 37°6'N latitudes, and 68°7'E and 97°25'E longitudes, creating a vast geographical spread.
Tropic of Cancer
The Tropic of Cancer (23°30'N) passes almost through the middle of the country, dividing India into two nearly distinct climatic zones: tropical and subtropical.
Standard Meridian of India
Calculated along 82°30'E meridian passing through Mirzapur in Uttar Pradesh, it sets the Indian Standard Time (IST) for the whole country to prevent time confusion.

Frequently Asked Questions
Why is there a time difference of two hours between Gujarat and Arunachal Pradesh?
Due to a longitudinal span of nearly 30 degrees from west to east, the sun rises about two hours earlier in Arunachal Pradesh compared to Gujarat. However, the Indian Standard Time (IST) is kept uniform across the country using the 82°30'E meridian.
Why is India's location at the head of the Indian Ocean considered advantageous?
It provides India with a central trans-Indian Ocean route connecting European countries in the west with countries of East Asia, facilitating maritime trade, communication, and cultural exchange easily.
Which countries share land boundaries with India?
India shares its land boundaries with Pakistan and Afghanistan to the northwest, China, Nepal, and Bhutan to the north, and Myanmar and Bangladesh to the east.
