Taiwan Jet Lag Calculator

Concretely: London → Taipei = 8 h, New York → Taipei = 13 h, Tokyo → Taipei = 1 h, Sydney → Taipei = 2 h. Six-plus hours of shift — arriving at UTC+8 — is where Taiwan trips get serious. Eastbound arrivals to Taiwan wake at absurd local hours; westbound arrivals fade by late afternoon in Taipei.

Both need deliberate light management. Two Taiwan specifics compound the shift: Taipei sits at 9 m (altitude makes poor sleep feel worse), and East Asia sits on the Asia travel circuit most Taiwan itineraries follow. Reference frame for Taiwan: Taipei keeps UTC+8 and sits 9 m above sea level in East Asia, with that same offset in every season.

Before you fly to Taiwan: move bedtime and meal times 30–60 minutes per day toward Taipei time for 3–4 days. In the air on the Taiwan route (arrival UTC+8), hydrate hard and skip alcohol. Sleep only when it is night in Taipei, so the cabin previews Taiwan hours.

Morning light is the strongest reset signal Taiwan offers at this shift size. In Taipei (UTC+8), get it outdoors before 10am local. Dry cabin air quietly drains you on the way to Taiwan; an extra 500 ml of water per 3 hours in the air keeps the Taipei arrival day survivable.

Applied to this East Asia trip: 8 hours east from London to Taipei maps to about 8 reset days, so a Taiwan itinerary should front-load outdoor time on days one to 8.

Sleep follows light in Taiwan: book a dark room in Taipei (9 m), keep it cool (16–20°C), and wear a mask if the early sunrise leaks through the blinds. If Taiwan wakes you at 4am on night one in Taipei, stay dark and still — checking the clock anchors wakefulness. If the afternoon slump hits in Taipei, nap 20–30 minutes maximum, before 3pm Taiwan time.

Or push through with a walk in Taiwan — long naps push adjustment back a day. Practical baseline: lights out in a dark 16–20°C Taipei room (9 m, UTC+8), and no evening alcohol for the first two nights while the Taiwan clock settles.
