Best overlap: 8:30 AM to 12:30 PM in Manchester is 2:00 PM to 6:00 PM in Delhi.
The sweet spot is 8:30 AM to 12:30 PM Manchester time, matching 2:00 PM to 6:00 PM in Delhi. Roughly 4 hours of common time means scheduling is manageable; just avoid the very edges of the window. Heads up: because Manchester changes its clocks and Delhi doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
London to New York is five hours apart, except for the five weeks a year when it isn't. Exact overlap windows for every US zone, the 2026 DST mismatch dates, and where to put the recurring sync. -
