For meetings, begin with the shared business-hours window above. Confirm the date with every participant because abbreviations such as EST, EDT, BST, and CEST describe specific standard or daylight offsets rather than an automatically changing regional clock.
This converter treats IST as UTC+05:30 and GMT as UTC+00:00. Use the city-based converter when you need automatic seasonal IANA timezone rules for a future date.
