Austria Jet Lag Calculator

Austria keeps a single reference offset of UTC+1 across Vienna, so the mental math never changes mid-trip. The size of your Austria jet lag is the absolute gap between your home offset and Vienna's UTC+1.

Context for the adjustment: Vienna rests at 171 m above sea level, and Austria's position in Western Europe shapes both flight routing and how much daylight you meet on arrival. Reference frame for Austria: Vienna keeps UTC+1 and sits 171 m above sea level in Western Europe, with daylight saving nudging summer clocks an hour.

Day one in Vienna: sunlight before midday. Meals go on the local clock in Austria, and lights-out stays no earlier than 9:30pm so the body accepts the new zone. Three levers run the Austria recovery: light, sleep timing and hydration.

Start with pre-flight drift for Austria — 30–60 minutes per day toward Vienna time. Hold the line in the air for Austria: water instead of wine. Caffeine before noon only, and set the watch to Vienna time, UTC+1.

Direction changes the bill: flying to Austria eastward from London costs about 1 days of recovery. The westward routing to Vienna costs only 0.7 — the body clock delays to Austria more easily than it advances. Applied to this Western Europe trip: 1 hours east from London to Vienna maps to about 1 reset days, so a Austria itinerary should front-load outdoor time on days one to 1.

Near-4am wakings are part of night one in Vienna (171 m, UTC+1); stay dark and still, skip the clock-checking, and Austria nights settle by the third. For shifts over six hours — into Austria, that means the 1-hour London gap — 0.5–3 mg of melatonin at Vienna bedtime (UTC+1) pulls the clock faster in 3–4 nights. Clear Austria dosing with a clinician first.

Cap naps at 20–30 minutes and finish them by 3pm Vienna time (UTC+1); anything longer steals the night that actually resets your clock to Austria. Practical baseline: lights out in a dark 16–20°C Vienna room (171 m, UTC+1), and no evening alcohol for the first two nights while the Austria clock settles.
