About These Time Zones
GMT — Greenwich Mean Time (UTC) (UTC+0, all year) covers the global UTC reference.
IST — India Standard Time (UTC+5:30, all year) covers Delhi, Mumbai, Bengaluru.
Neither zone observes daylight saving, so the difference between them is the same every day of the year.
Scheduling Across GMT and IST
For calls and meetings, aim for the overlap of normal working hours in both zones — the conversion table above makes the window easy to spot. Morning on the western side of the pair usually meets afternoon on the eastern side.
