Why is India on a half-hour timezone (UTC+5:30)?

India's UTC+5:30 offset was established in 1905 as a compromise between the time zones of Bombay (UTC+4:52) and Calcutta (UTC+5:54) when India unified under British rule. Several countries use half-hour or quarter-hour offsets — including Nepal (UTC+5:45), Iran (UTC+3:30), and parts of Australia (UTC+9:30) — to better align solar noon with clock noon across their territory.
