Tanzania Jet Lag Calculator

From London the shift to Dodoma is 3 hours eastward; New York faces 8; Tokyo 6; Sydney 7. A gap this size is a weekend problem, not a week problem: Dodoma mornings feel early at first. By day three or four in Tanzania, your body has caught up.

Two Tanzania specifics compound the shift: Dodoma sits at 1,120 m (altitude makes poor sleep feel worse), and East Africa sits on the Africa travel circuit most Tanzania itineraries follow. Reference frame for Tanzania: Dodoma keeps UTC+3 and sits 1,120 m above sea level in East Africa, with that same offset in every season.

Move 30–60 minutes daily toward Dodoma time (UTC+3) for 3–4 days pre-flight. Keep the Tanzania flight alcohol-free. Treat the cabin as a preview of Tanzania time rather than home time.

Each eastbound zone costs about one recovery day, each westbound zone about two-thirds of a day — so the London–Dodoma leg (eastbound, 3 hours) bills you about 3 days, while flying the opposite direction would cost only 2. Dry cabin air quietly drains you on the way to Tanzania; an extra 500 ml of water per 3 hours in the air keeps the Dodoma arrival day survivable. Applied to this East Africa trip: 3 hours east from London to Dodoma maps to about 3 reset days, so a Tanzania itinerary should front-load outdoor time on days one to 3.

A 10-minute warm shower an hour before bed speeds the core-temperature drop that starts sleep — a real head-start on the first jangled Tanzania nights in Dodoma. Naps are a tool with a limit in Tanzania: 20–30 minutes, done by 3pm Dodoma time, never as a substitute for a full local night.

The Tanzania sleep kit for Dodoma at 1,120 m: an eye mask, earplugs, curtains closed against the early sunrise, and a room held near 16–20°C. Practical baseline: lights out in a dark 16–20°C Dodoma room (1,120 m, UTC+3), and no evening alcohol for the first two nights while the Tanzania clock settles.
