Best time to call London from Bengaluru
London is 4 hours behind Bengaluru. Calling London from Bengaluru works best between 13:30–17:00 Bengaluru time, which lands at 09:00–12:30 for London. The shared window does not open until the Bengaluru afternoon, so mornings there are effectively solo working time.
3h 30m is enough for one solid meeting a day, but not two. Treat it as a single block and defend it.
Avoid the first and last fifteen minutes of that range. Those edges are where one side is either still settling in or already packing up, and a call that runs five minutes over pushes someone past the end of their day.

Cross-timezone workday overlap and collaboration
3h 30m of shared time is enough to run one dependable synchronous block a day. Put anything that needs discussion inside it and let everything else happen in writing.
Treat the gap as a handoff rather than a delay. Whoever finishes first should leave the next step written down and unambiguous; 4 hours later the other side picks it up without needing to ask a question that would cost another full day.
Watch for fatigue on recurring meetings. A weekly call that sits at the very edge of someone's evening is tolerable once and corrosive after a month. If the only workable slot is uncomfortable for one side, rotate it, or accept that the meeting should be a document instead.
Practical rules for this pairing
- Book recurring meetings inside 13:30–17:00 Bengaluru time and leave the rest of the day for focused work.
- Keep the first hour after London comes online free of meetings, so anything blocking overnight gets picked up immediately.
- Leave at least thirty minutes of the window unbooked as a buffer for anything urgent.
