About the Sofia → Cairo route

The route from Sofia, Bulgaria to Cairo, Egypt covers roughly 1,574 kilometres in a southeast direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 2.8 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.

Sofia 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. 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.

Business-hours overlap

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

Both cities observe daylight saving time. The hour offset on this route can shift by one hour twice a year (typically March and October/November), and the two clocks rarely change on the exact same date — expect a transient 1-hour mismatch for two to three weeks per transition.
