FAQ

What time is it in UTC when it's noon in Chicago?
Use the converter above — enter 12:00 on your date in Chicago and you'll get the exact UTC local time, DST included.
Why does the time difference change during the year?
Chicago and UTC may observe daylight saving on different schedules (or not at all), so the gap between them shifts on clock-change dates.
