About the Bengaluru → Chennai route

The route from Bengaluru, India to Chennai, India covers roughly 290 kilometres in a due east direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 1.3 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.

Bengaluru is in the tropics, so day length varies only slightly across the year. Light cues for the circadian system stay strong year-round. Chennai 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 Bengaluru that window runs 09:00 to 18:00; in Chennai 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
