Question

The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west but the watches show the same time. How does this happen?

Answer 1

• The standard time for India is taken as the time along the Standard Meridian of India (82°30’E) passing through Mirzapur (in Uttar Pradesh).
• 68° 7′ E is the Westernmost longitude of India.
• The easternmost longitude of India is 97° 25′ E.
• As we move from Gujarat in the West to Arunachal Pradesh in the East, there will be a time delay of two hours.
• India is divided into almost two equal parts, by the Tropic of Cancer (23° 30’N).
• The extent of latitude in India is 8°4’N and 37°6’N
• As one moves from southern India to north of India, the extent of latitude influences the duration of day and night.
