Best overlap: 2:00 PM to 6:00 PM in Dhaka is 8:00 AM to 12:00 PM in Manchester.
Schedule calls for 2:00 PM to 6:00 PM in Dhaka — your colleagues in Manchester will be online from 8:00 AM to 12:00 PM. Around 4 hours of overlap is enough to work comfortably, as long as meetings don't drift to the end of one team's day. These times hold for most of the year, but Manchester's daylight saving (which Dhaka doesn't use) shifts them by an hour twice annually.
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. -
