About
Working across 6 hours of time difference
A 6 hours offset puts Chicago and London in the medium-difficulty band. You typically have a 2–4 hour window each day where both cities are at work — usually early afternoon in the western city, late morning or early afternoon in the eastern one. Keep recurring meetings inside that window.
Daylight Saving Time can shift the gap by an hour twice a year. The North American DST window does not align with the European one, so the offset between Chicago and London can drift in late March and again in early November. Use this page to re-check your standing meeting on each transition.
FAQ
What's the best time for a meeting between Chicago and London?
Best overlap: 7:00 AM–10:00 AM Chicago time (2/2 zones in business hours). The strongest business-hour overlap is UTC 12:00–16:00, which is Chicago 7:00 AM–10:00 AM and London 1:00 PM–4:00 PM locally.
What is the time difference between Chicago and London?
Chicago is currently UTC-05:00 and London is UTC+01:00, a difference of 6 hours. The exact gap can shift by one hour when one city switches to or from Daylight Saving Time.
Should we shift the meeting if one city changes Daylight Saving Time?
Yes — when only one of the two cities observes DST, the overlap window moves by an hour. Re-check this page in the weeks around March/April and October/November and adjust your standing meeting accordingly. The 24-hour grid below always reflects the current correct offset.
Can I schedule a daily standup that works for both Chicago and London?
It's tight but doable. A meeting early in London's day (around 8–9am) catches the other city at the end of theirs. Rotate the burden monthly to keep it fair.
