About the Cairo → Antananarivo route

The route from Cairo, Egypt to Antananarivo, Madagascar covers roughly 5,712 kilometres in a due south direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 7.6 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.

Cairo is in the subtropics. Day length varies by roughly two hours between summer and winter; light remains a reliable circadian cue most of the year. Antananarivo is in the tropics, so day length varies only slightly across the year. Light cues for the circadian system stay strong year-round.

Business-hours overlap

Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 9 hours. In Cairo that window runs 09:00 to 18:00; in Antananarivo 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.

Daylight saving on this route

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).

Is jet lag worse flying east or west on this route?

No circadian shift is required between these two cities.

Should I take melatonin for the Cairo → Antananarivo trip?

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.

Do I need a pre-trip schedule shift for Cairo → Antananarivo?

For a shift under two hours, pre-trip adjustment is usually not worth the effort.

What chronotype handles this route best?
