Jet lag plan
Prague is 10 hours behind Suva. You're traveling west — the easier direction. Your body delays its clock.
About 16,188 km due north · approximately 19.6-hour non-stop flight · an ultra-long-haul flight.
The route from Suva, Fiji to Prague, Czechia covers roughly 16,188 kilometres in a due north direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 19.6 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.
Suva is in the tropics, so day length varies only slightly across the year. Light cues for the circadian system stay strong year-round. Prague 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.
With a 10-hour offset, the standard 09:00–18:00 working days in Suva and Prague do not overlap. Live collaboration on this route requires at least one side to take an early or late call. The least costly compromise is usually an early-morning call in Prague and a late-evening call in Suva.
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).
If you are a lark (morning type): Westward travel is the easier direction and larks usually feel close to baseline within 5 days. The risk for larks is overshooting: stay up later than you feel like at the destination for the first two nights to avoid waking before local sunrise.
If you are a night owl (evening type): Westward travel suits owls because the body prefers delaying over advancing. A 10-hour westward shift typically clears in 5 days. Stay outside in the evening light at the destination and avoid early-morning bright light for the first three days.

Prague is currently 10 hours behind Suva. 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).
Westward travel — which this route is — is the easier direction. Your body delays its clock, which is closer to its natural tendency. Most travellers clear a 10-hour westward shift in 7 days.
For a 10-hour shift, 0.3 to 0.5 mg of melatonin taken three to five hours before target bedtime at the destination is the dose supported by the Cochrane review. Higher doses (3–5 mg) do not advance phase better and increase morning grogginess. Start one day before departure.
Yes — for shifts of four hours or more, shifting bedtime and wake time by one hour per day, starting three days before departure, materially reduces post-arrival jet lag.
Owls (evening types) recover faster on westward routes because the body prefers delaying over advancing. Larks may overshoot — they should stay up later than they feel like at the destination for the first two nights.
