Latitudinal and Longitudinal Extent
India extends from 8°4'N to 37°6'N latitudes and 68°7'E to 97°25'E longitudes, resulting in a vast territorial expanse with significant climatic and time variations.
Indian Standard Time (IST)
Calculated based on the 82°30'E meridian passing through Mirzapur, IST is 5 hours and 30 GMT ahead of Greenwich Mean Time to maintain a uniform time across the country.
Geographical Area and Rank
India covers an area of 3.28 million square kilometers, accounting for about 2.4% of the world's total land area, making it the 7th largest country globally.
Strategic Location and Frontiers
India shares land boundaries with seven countries and is bounded by the Arabian Sea, the Bay of India, and the Indian Ocean, giving it a central location on international trade routes.
Tropic of Cancer
The 23°30'N latitude passes almost through the middle of the country, dividing India into tropical and subtropical climatic zones.

Frequently Asked Questions
Why is the difference between the local time of Gujarat and Arunachal Pradesh two hours despite using the same IST?
India has a longitudinal extent of nearly 30 degrees. Since the earth takes 4 minutes to rotate 1 degree, the actual time difference between the easternmost (Arunachal Pradesh) and westernmost (Gujarat) points is 120 minutes (2 hours). However, India uses a single meridian (82°30'E) for standard time to avoid confusion in schedules.
What is the significance of India's peninsular location?
India's peninsular shape extends into the Indian Ocean, providing it with a long coastline of over 7,500 km. This facilitates easy maritime communication and trade routes connecting Europe, Africa, and East/Southeast Asia.
Which countries share land borders with India?
India shares its land borders with Pakistan and Afghanistan to the northwest, China, Nepal, and Bhutan to the north, and Myanmar and Bangladesh to the east.
