Chicago and Lisbon are 6h apart. When it's 9 AM in Chicago, it's already 3:00 PM in Lisbon — meaning Lisbon's working day is well underway before Chicago's morning has properly started.
The 2h of overlapping business hours is your synchronous window. Use it for decisions, code reviews, and anything that genuinely requires two people to think together. Push everything else — status updates, documentation questions, non-blocking feedback — into async channels so you're not burning your shared window on things that could be an email.
For any recurring sync between Chicago and Lisbon, set the calendar invite in one canonical timezone and confirm the other side sees the correct local time. DST transitions can silently shift the effective meeting time by an hour for several weeks without either party noticing until someone is waiting alone on the call.
The bigger risk isn't the 6h gap — it's that the 2h overlap creates a false sense of availability. Both sides are reachable at the same time, so meetings proliferate. The most effective Chicago–Lisbon teams treat their overlap window as a protected resource: one synchronized meeting per day maximum, async-first for everything else.
Chicago is UTC-5 and Lisbon 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 Lisbon on March 29, so the gap between them shifts by 1 hour during the spring and fall mismatch window.
Chicago and Lisbon share 2h of business-hours overlap (assuming 9 AM–5 PM local time for both).
