Best overlap: 2:00 PM to 6:00 PM in Chennai is 8:30 AM to 12:30 PM in Manchester.
Both offices are open during 2:00 PM to 6:00 PM Chennai time, which is 8:30 AM to 12:30 PM in Manchester. Manchester is 5.5 hours behind Chennai. That leaves about 4 hours of common time — enough for a meeting or two, so use it deliberately. Heads up: because Manchester changes its clocks and Chennai doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
