Thats because of longitudinal difference as we know 1 degree means different of 4 minutes thats why this happens

Introduction
The difference in sunrise times between Arunachal Pradesh and Gujarat can be attributed to their geographical locations and the longitudinal position of each state within India.
Geographical Location
- Arunachal Pradesh is located in the northeastern part of India, while Gujarat is in the western region.
- The two states are situated at different longitudes, which affects the timing of sunrise.
Longitude Differences
- Arunachal Pradesh is approximately at 97° E longitude.
- Gujarat is located around 72° E longitude.
- The Earth rotates 360 degrees in about 24 hours, meaning it rotates about 15 degrees every hour.
Sunrise Calculation
- For every degree of longitude, there is a time difference of about 4 minutes.
- The longitudinal difference between Arunachal Pradesh and Gujarat is roughly 25 degrees.
- Therefore, the time difference is approximately 25 degrees × 4 minutes = 100 minutes, or about 1 hour and 40 minutes.
Elevation and Geography
- Arunachal Pradesh has varying elevations, which can also influence local sunrise times.
- The mountainous terrain may cause the sun to rise earlier in some areas compared to the flatlands of Gujarat.
Conclusion
The combination of longitude, geographical location, and terrain leads to Arunachal Pradesh experiencing sunrise approximately 2 hours earlier than Gujarat. Understanding these geographical factors provides insight into the natural phenomena of sunrise across different regions.
