About the Hangzhou → Shanghai route

The route from Hangzhou, China to Shanghai, China covers roughly 165 kilometres in a northeast direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 1.2 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.

Hangzhou 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. Shanghai 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 Hangzhou that window runs 09:00 to 18:00; in Shanghai 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
