About converting India Standard Time to Greenwich Mean Time
India Standard Time (IST) and Greenwich Mean Time (GMT) are in different regions, so meetings, calls, and live events need a quick conversion between them. The tool above shows the current time in both zones side by side and lets you convert any specific time in seconds. Everything runs in your browser using an up-to-date time-zone database, so the result is always accurate — including the hour shifts that happen when daylight saving time starts or ends.
Frequently asked questions
How do I convert IST to GMT?
Use the converter above: it shows the current time in both India Standard Time and Greenwich Mean Time, and lets you enter any IST time to see the matching GMT time instantly.
Does this account for daylight saving time?
Yes. The conversion uses your browser's up-to-date time-zone database, so the offset automatically reflects daylight saving time when it is in effect.
Is the IST to GMT time difference fixed?
Not always. Because regions start and end daylight saving on different dates, the difference between India Standard Time and Greenwich Mean Time can shift by an hour for part of the year. The live converter always shows the current, correct difference.
