Jet lag plan
Tunis and Edinburgh share the same time zone.
About 2,354 km due north · approximately 3.7-hour non-stop flight · a long-haul flight.
The route from Tunis, Tunisia to Edinburgh, United Kingdom covers roughly 2,354 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 3.7 hours. Both cities sit in the northern hemisphere, so the seasonal direction of daylight (longer days in June, shorter in December) matches between origin and destination.
Tunis 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. Edinburgh is in the subarctic zone. In summer the sun sets briefly or not at all; in winter daylight may drop below five hours. The season of travel changes light-based jet-lag protocols significantly.
Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 9 hours. In Tunis that window runs 09:00 to 18:00; in Edinburgh it is 09:00 to 18:00. This is the realistic window for live meetings, customer calls, or pair work without forcing either end out of normal hours.
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).
The great-circle distance from Tunis to Edinburgh is about 2,354 kilometres. A typical non-stop flight takes around 3.7 hours at standard cruise speed; routes with connections add two to four hours.
Tunis and Edinburgh share the same time zone, so there is no clock offset on this route.
No circadian shift is required between these two cities.
For a shift of 0 hours, melatonin offers little benefit beyond what consistent light exposure already provides. The Cochrane review on jet-lag melatonin shows the strongest effects on shifts of five hours or more.
For a shift under two hours, pre-trip adjustment is usually not worth the effort.
Chronotype does not affect adjustment on a same-time-zone route.
