Jet lag plan
Kigali is 3.5 hours behind Delhi. You're traveling west — the easier direction. Your body delays its clock.
About 6,057 km southwest · approximately 8-hour non-stop flight · an ultra-long-haul flight.
The route from Delhi, India to Kigali, Rwanda covers roughly 6,057 kilometres in a southwest direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 8 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.
Delhi 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. Kigali 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.
Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 5.5 hours. In Delhi that window runs 12:30 to 18:00; in Kigali it is 09:00 to 14:30. 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 3.5-hour westward shift typically clears in 2 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 Delhi to Kigali is about 6,057 kilometres. A typical non-stop flight takes around 8 hours at standard cruise speed; routes with connections add two to four hours.
Kigali is currently 3.5 hours behind Delhi. 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 3.5-hour westward shift in 3 days.
For a 3.5-hour shift, 0.3 to 0.5 mg of melatonin taken three to five hours before target bedtime at the destination is the dose supported by the Cochrane review. Higher doses (3–5 mg) do not advance phase better and increase morning grogginess. Start one day before departure.
For a 3.5-hour shift, one or two days of one-hour pre-trip bedtime adjustment helps but is not essential.
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.
