Question

why is 5:30 pm in India and 12:00 noon in londan

Answer 1

hey mate here is your answer

If we had one single time zone for Earth, noon would be the middle of the day in some places, but it would be morning, evening, and the middle of the night in others. Since different parts of Earth enter and exit daylight at different times, we need different time zones. ... Each time zone is 15 degrees of longitude wide.

I hope this helps you
