Frequently Asked Questions
Why is the difference between the times of sunrise in Arunachal Pradesh and Gujarat two hours?
Due to a longitudinal gap of nearly 30 degrees between easternmost Arunachal Pradesh and westernmost Gujarat, and knowing that the Earth takes 4 minutes to rotate 1 degree, the total time difference is about 120 minutes or 2 hours.
Which is the Standard Meridian of India and why is it chosen?
The Standard Meridian is 82°30'E, passing through Mirzapur in Uttar Pradesh. It was chosen because it is centrally located on the country's longitude, preventing time confusion across different states.
How does India's coastline help in international trade?
India's long coastline and peninsular shape projecting into the Indian Ocean provide natural harbors and easy maritime routes connecting West Asia, Africa, Europe on the west, and Southeast/East Asia on the east.
