Question: why is the difference between the duration of day and night?
Answer: 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.
