The 6h offset between Chicago and Dublin is not just a number — it reshapes the entire rhythm of collaboration. Dublin clocks out while Chicago is still at lunch. Teams that don't plan this deliberately spend their overlap on firefighting instead of actual work.
The 2h overlap window runs at the edge of both teams' days. For Chicago's side it's a late-morning meeting; for Dublin it's early afternoon. Neither is painful, which is exactly why it works. Anchor your recurring sync here and treat the rest of the day as async territory.
The less obvious scheduling risk is daylight saving time mismatch. Chicago and Dublin may not shift their clocks on the same date. A meeting booked as "10 AM CHI" in January might show up as "11 AM CHI" in a colleague's calendar in March if your calendar app doesn't handle DST transitions correctly. Check the DST note on this page before setting up recurring meetings.
Add the rest of your team above and the planner scales to everyone at once. A three-city team spanning Chicago, Dublin, and a third timezone often has less overlap than any two-city pair in isolation — surfacing that constraint early prevents scheduling that works on paper but burns people out in practice.
Chicago is UTC-5 and Dublin is UTC+1, a difference of 6h. This gap may shift by 1 hour during DST transitions.
The best meeting time is during the 2h of shared business hours — typically 9:00 AM to 11:00 AM CDT.
Yes. Both cities observe daylight saving time, but on different schedules. Chicago springs forward on March 8 and Dublin on March 29, so the gap between them shifts by 1 hour during the spring and fall mismatch window.
Chicago and Dublin share 2h of business-hours overlap (assuming 9 AM–5 PM local time for both).
