Question

Why is Bangladesh half an hour ahead of
India?​

Answer 1

Answer:

Indian standard time(IST) is usually UTC(+5:30) . So there is a 30 minute difference there. India nor Bangladesh observes DST(Day light saving) and therefore always have a 30 min gap

Answer 2

Answer:

Bangladesh is half an hour ahead of India because sun rises half an hour ago in Bangladesh compared to the area of Indian standard time (IST). If IST was based on Assam, India and Bangladesh both would have the same time.
