Explanations:India is a vast country that spans a significant longitudinal distance, which results in a time difference between its easternmost and westernmost parts. The longitudinal distance between Arunachal Pradesh, located in the far east of India, and Gujarat, located in the far west, is approximately 28 degrees. This longitudinal distance translates into a time difference of about 2 hours.
The Earth rotates 360 degrees in 24 hours, which means that each degree of longitude corresponds to a time difference of 4 minutes. Therefore, a longitudinal distance of 28 degrees would result in a time difference of approximately 2 hours and 8 minutes. However, for practical purposes and standardization, India has adopted a single time zone, which is based on the longitude of 82.5 degrees east, corresponding to the city of Allahabad. This means that while there is a natural time difference, the entire country operates on a single time zone to maintain uniformity.
Despite the single time zone, the natural time difference between Arunachal Pradesh and Gujarat is still approximately 2 hours. This is because the sun rises earlier in the east due to the Earth's rotation. As a result, people in Arunachal Pradesh experience sunrise almost 2 hours earlier than those in Gujarat.
Understanding this concept is crucial for comprehending the geographical and temporal differences within a large country like India. It also highlights the importance of standardizing time zones for practical and administrative purposes, even when there are natural time differences due to longitudinal distances.
