Question

Why 82 30' E has been selected as the Standard Meridian of India? Why the
fference between the duration of the day and night hardly felt at Kanyakumari but
et so in Kashmir?​

Answer 1

Answer:

This is due to the fact that Kanyakumari being towards south of India is located near the equator , while Kashmir is away from the equator (in the temperate zone). ... Hence, difference between the duration of day and night hardly felt in Kanyakumari but not so in Kashmir.

Answer 2

Explanation:

From Gujarat to Arunachal Pradesh there is a time lag of two hours. Hence, time along the Standard Meridian of India (82° 30' E) passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for the whole country.

As Kanyakumari is quite near the equator at 8°4'N the day-night difference is hardly one hour there, and therefore, the duration of day and night is hardly felt at Kanyakumari. ... Kashmir is over 30° away from the equator and so the difference in duration of day and night is more there and we feel that difference.
