Meeting Planner
Plan a GMT to IST meeting
Greenwich Mean Time is a UTC+00:00 time standard commonly used in Europe, Africa, aviation, and global schedules. India Standard Time is the fixed UTC+05:30 time used throughout India and does not observe daylight saving time.
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 GMT as UTC+00:00 and IST as UTC+05:30. Use the city-based converter when you need automatic seasonal IANA timezone rules for a future date.
