7 PM IST in London: what to know
7 PM India Standard Time is one of the most useful India-to-UK meeting slots. It lands at 1:30 PM in London 鈥?comfortably within the working day for UK participants. India does not observe daylight saving time, so the gap shifts slightly when the UK clock changes: in summer (BST), 7 PM IST is 1:30 PM BST; in winter (GMT), it is still 1:30 PM GMT. The result is identical clock time year-round. This slot gives the London side time to act on meeting outcomes before end of day, making it ideal for project reviews, sprint planning, or daily standups between India and UK teams.
For one-time meetings, write both local times in the invite. For recurring meetings, check daylight saving transitions in late March and late October. Use the Meeting Time Finder to compare more cities.

How does the India-UK gap change with UK daylight saving?
India Standard Time (IST) never changes. In UK winter (GMT, UTC+0), IST is 5.5 hours ahead. In UK summer (BST, UTC+1), IST is 4.5 hours ahead. This shifts the London clock-time by 1 hour during the UK DST period 鈥?but 7 PM IST stays at 1:30 PM London regardless of season.
What is the full India-London working overlap?
The useful India-London overlap runs from approximately 1:30 PM to 5 PM London (7 PM to 10:30 PM IST). This requires India teams to work late evening, which is standard practice for UK-facing roles in Indian IT and services.
