Jordan Jet Lag Calculator

One useful constant: Amman — and with it the Jordan clock — stays pinned to UTC+3 for the whole trip. Two Jordan specifics compound the shift: Amman sits at 766 m (altitude makes poor sleep feel worse), and Western Asia sits on the Asia travel circuit most Jordan itineraries follow.

From London the shift to Amman is 3 hours eastward; New York faces 8; Tokyo 6; Sydney 7. Reference frame for Jordan: Amman keeps UTC+3 and sits 766 m above sea level in Western Asia, with that same offset in every season.

Dry cabin air quietly drains you on the way to Jordan; an extra 500 ml of water per 3 hours in the air keeps the Amman arrival day survivable. Each eastbound zone costs about one recovery day, each westbound zone about two-thirds of a day — so the London–Amman leg (eastbound, 3 hours) bills you about 3 days, while flying the opposite direction would cost only 2.

On arrival, anchor the new rhythm with an outdoor morning in Amman and meals on Jordan time from the first day. Applied to this Western Asia trip: 3 hours east from London to Amman maps to about 3 reset days, so a Jordan itinerary should front-load outdoor time on days one to 3.

The Jordan sleep kit for Amman at 766 m: an eye mask, earplugs, curtains closed against the early sunrise, and a room held near 16–20°C. 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 Jordan nights in Amman.

Naps are a tool with a limit in Jordan: 20–30 minutes, done by 3pm Amman time, never as a substitute for a full local night. Practical baseline: lights out in a dark 16–20°C Amman room (766 m, UTC+3), and no evening alcohol for the first two nights while the Jordan clock settles.
