About the Baltimore → Manaus route

The route from Baltimore, United States to Manaus, Brazil covers roughly 5,012 kilometres in a southeast direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 6.8 hours. This route crosses the equator. The destination's season is reversed relative to the origin, which can amplify the perceived disorientation of jet lag — your body lands not just in a different clock but in a different daylight regime.

Baltimore is in the temperate zone. Day length varies by four to six hours between summer and winter, so the season of your trip materially affects available morning and evening light. Manaus sits within ten degrees of the equator, so day length is nearly constant year-round (about 12 hours). Sunset and sunrise stay close to 06:00 and 18:00 regardless of season.

Business-hours overlap

Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 9 hours. In Baltimore that window runs 09:00 to 18:00; in Manaus it is 09:00 to 18:00. This is the realistic window for live meetings, customer calls, or pair work without forcing either end out of normal hours.

Daylight saving on this route

Only one of the two cities observes daylight saving time, so the offset between them shifts by one hour twice a year. If you have recurring meetings on this route, double-check the local time around the DST transitions (March and October/November in the northern hemisphere).
