Jet lag plan
Bengaluru is 1.5 hours behind Bandung. You're traveling west — the easier direction. Your body delays its clock.
About 3,986 km northwest · approximately 5.6-hour non-stop flight · a long-haul flight.
The route from Bandung, Indonesia to Bengaluru, India covers roughly 3,986 kilometres in a northwest direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 5.6 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.
Bandung 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. Bengaluru is in the tropics, so day length varies only slightly across the year. Light cues for the circadian system stay strong year-round.
Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 7.5 hours. In Bandung that window runs 10:30 to 18:00; in Bengaluru it is 09:00 to 16:30. This is the realistic window for live meetings, customer calls, or pair work without forcing either end out of normal hours.
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.
If you are a lark (morning type): Westward travel is the easier direction and larks usually feel close to baseline within 2 days. The risk for larks is overshooting: stay up later than you feel like at the destination for the first two nights to avoid waking before local sunrise.
If you are a night owl (evening type): Westward travel suits owls because the body prefers delaying over advancing. A 1.5-hour westward shift typically clears in 1 days. Stay outside in the evening light at the destination and avoid early-morning bright light for the first three days.

The great-circle distance from Bandung to Bengaluru is about 3,986 kilometres. A typical non-stop flight takes around 5.6 hours at standard cruise speed; routes with connections add two to four hours.
Bengaluru is currently 1.5 hours behind Bandung. 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.
Westward travel — which this route is — is the easier direction. Your body delays its clock, which is closer to its natural tendency. Most travellers clear a 1.5-hour westward shift in 1 days.
For a shift of 1.5 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.
For a shift under two hours, pre-trip adjustment is usually not worth the effort.
Owls (evening types) recover faster on westward routes because the body prefers delaying over advancing. Larks may overshoot — they should stay up later than they feel like at the destination for the first two nights.
