Sunrise in eastern Arunachal Pradesh would be about two hours before the sunrise in western Gujarat.
The Earth rotates 360 degrees in 24 hours, meaning 15 degrees of longitude corresponds to 1 hour, or 1 degree corresponds to 4 minutes. The longitudinal extent of India is approximately from 68°7′ E in the west (Gujarat) to 97°25′ E in the east (Arunachal Pradesh). The difference in longitude is about 97°25′ – 68°7′ ≈ 29°18′, which is close to 30 degrees.
