1. Why 82°30'E has been selected as the Standard Meridian of India?
There is a longitudinal extent of about 30° from Gujarat to Arunachal Pradesh, resulting in a time difference of nearly two hours. To maintain a uniform standard time for the entire country and avoid confusion in railway and flight timetables, 82°30'E—which passes centrally through Mirzapur in Uttar Pradesh—has been chosen as the Standard Meridian of India.

2. Why is the difference between the durations of day and night hardly felt at Kanniyakumari but not so in Kashmir?
Kanniyakumari is situated close to the Equator (around 8°4'N), where the duration of day and night is almost equal throughout the year. On the other hand, Kashmir is located far away from the Equator (around 37°6'N), where the difference in the duration of day and night increases significantly with latitude.
