IST currently runs on UTC+5:30 and GMT on UTC+0, so IST is 5 hours 30 minutes ahead of GMT. IST does not observe daylight saving time, and GMT is currently on standard time. Because both cities follow their own clock rules, the 5 hours 30 minutes gap you see today can shift by an hour around the spring and autumn changeovers, which is why this page calculates every value live from the official time zone database instead of a fixed offset. For meetings, the best shared working window today is 15:00–18:00 IST time, when both offices are inside normal 09:00–18:00 hours. Use the planner above to drag across a range, compare more cities, then copy a summary or add the slot straight to Google Calendar.
Daylight saving in IST and GMT
IST keeps the same offset all year, so any change in the gap comes from the other location. GMT follows European rules: clocks go forward on the last Sunday in March and back on the last Sunday in October, at 01:00 UTC.
