About the Denpasar → Nanjing route

The route from Denpasar, Indonesia to Nanjing, China covers roughly 4,545 kilometres in a due north direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 6.2 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.

Denpasar sits within ten degrees of the equator, so day length is nearly constant year-round (about 12 hours). Sunset and sunrise stay close to 06:00 and 18:00 regardless of season. Nanjing 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 Denpasar that window runs 09:00 to 18:00; in Nanjing 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.
