About the Chongqing → Manila route

The route from Chongqing, China to Manila, Philippines covers roughly 2,192 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 3.5 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.

Chongqing 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. Manila 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 Chongqing that window runs 09:00 to 18:00; in Manila 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

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.
