Frequently asked questions

Working between Chicago and Delhi

The difference between Chicago and Delhi is not really a number, it's a daily rhythm. Delhi is 11.5 hours ahead of Chicago on the clock today, but the lived version is that Delhi is wrapping up the working day while Chicago is still in the morning, and the overlap people actually use is narrow. That gap, more than the raw offset, is what teams have to design around.

In Chicago, the working day picks up earliest in the financial districts- Chicago's downtown core wakes early and breaks for lunch at the usual hour. The mood in Delhi is its own story: Delhi settles into the evening at the usual hour, with the local commuter pattern setting the pace. If you are scheduling between the two, the heatmap above marks the rows where both patterns line up.

Daylight saving is the other thing to keep an eye on. United States shifts the clock on the second Sunday of March and the first Sunday of November; India either follows its region's DST pattern or stays put all year. When the two changes are weeks apart, the offset between Chicago and Delhi is one hour off the usual for that stretch, a cliff that catches recurring calendar invites unless your calendar app rebases them automatically. Pin the meeting to a city, not an offset, and the tool handles the rest.

For travellers, the 15h 08m flight is the short version of the story. The longer one is jet lag: roughly one day of adjustment per timezone crossed, which means a trip across the 12-hour gap costs about 12 groggy days on each side. Pilots and cabin crew swear by morning sunlight and an early walk; whatever your routine, the wall-clock numbers above are the source of truth for your first morning in the new city.
