QUESTIONS

How many hours is Seoul ahead of Chicago?

Seoul is 14 hours ahead of Chicago. That's calculated from each city's current UTC offset (UTC-5 for Chicago, UTC+9 for Seoul).

Does the time difference between Chicago and Seoul change during the year?

It can. Chicago observes daylight saving time, so the gap shifts by an hour when clocks change. The live clocks above always reflect the current, correct difference.

What's the best time to schedule a meeting between Chicago and Seoul?

There's no window where both Chicago and Seoul are in standard 9-to-5 hours at the same time, so a live call means one side joins early or late. Converge can find the least-bad slot from everyone's real availability.
