Jet lag plan
Algiers is 2 hours behind Istanbul. You're traveling west — the easier direction. Your body delays its clock.
About 2,284 km due west · approximately 3.6-hour non-stop flight · a long-haul flight.
The route from Istanbul, Turkey to Algiers, Algeria covers roughly 2,284 kilometres in a due west direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 3.6 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.
Istanbul 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. Algiers 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.
Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 7 hours. In Istanbul that window runs 11:00 to 18:00; in Algiers it is 09:00 to 16:00. This is the realistic window for live meetings, customer calls, or pair work without forcing either end out of normal hours.
Neither city observes daylight saving time, so the hour offset on this route is fixed year-round. This makes recurring schedules and calendar invites with collaborators on the other end safer than for DST-observing pairs.
If you are a lark (morning type): Westward travel is the easier direction and larks usually feel close to baseline within 2 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 2-hour westward shift typically clears in 1 days. Stay outside in the evening light at the destination and avoid early-morning bright light for the first three days.

Algiers is currently 2 hours behind Istanbul. Neither city observes daylight saving time, so the hour offset on this route is fixed year-round. This makes recurring schedules and calendar invites with collaborators on the other end safer than for DST-observing pairs.
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 2-hour westward shift in 2 days.
For a shift of 2 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 2-hour shift, one or two days of one-hour pre-trip bedtime adjustment helps but is not essential.
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.
