Best overlap: 11:00 AM to 6:00 PM in Manchester is 8:00 AM to 3:00 PM in Brasília.
Schedule calls for 11:00 AM to 6:00 PM in Manchester — your colleagues in Brasília will be online from 8:00 AM to 3:00 PM. Brasília is 3 hours behind Manchester, but the generous 7-hour window means both teams can meet well within their normal day. Because Manchester and Brasília don't both observe daylight saving, plan to re-check the overlap around March and November.
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. -
