Best overlap: 8:00 AM to 1:00 PM in Edinburgh is 1:45 PM to 6:45 PM in Kathmandu.
Keep meetings inside 8:00 AM to 1:00 PM in Edinburgh — that maps to 1:45 PM to 6:45 PM in Kathmandu. Kathmandu is 5.75 hours ahead of Edinburgh, leaving about 5 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Remember that Edinburgh shifts for daylight saving and Kathmandu doesn't, so recalculate the overlap after each clock change.
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. -
