Daylight saving in Mumbai

Mumbai does not observe daylight saving. Its offset is UTC+5:30 on every day of the year, which makes recurring meetings straightforward — once a slot is agreed in local time it stays correct indefinitely.

About Mumbai

Mumbai runs on India Standard Time, which is offset from UTC by five and a half hours — one of a small number of zones on a half-hour boundary. India has a single timezone despite spanning a considerable east-west distance, and it does not observe daylight saving, so the offset is fixed permanently. Any meeting booked on the hour elsewhere lands on the half hour here.
