Best Meeting Time: Seattle to Chicago
🕐 Live Timezone Overlap: Seattle & Chicago
Meetings between Seattle and Chicago hinge on a 7-hour window each working day. Seattle sits 2 hours ahead of Chicago at the time of writing, which puts the comfortable overlap at 9:00 AM to 4:00 PM Seattle time. Teams that work across these two cities tend to anchor their week-on-week sync into that block and push everything else to written updates. The widget below shows the exact mapping in both directions, including the small DST seasonal shift when one or both cities change clocks.
Time Difference: Seattle and Chicago
Chicago is currently 2 hours ahead of Seattle. The live offsets are Seattle UTC-7 and Chicago UTC-5. Seattle observes daylight saving and Chicago also observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
Seattle observes daylight saving time, and Chicago also observes DST. When either side switches, the offset shifts by an hour. The US and Europe also change clocks on different weekends, so for one week in spring and one in autumn the usual offset between US and European cities is off by an hour. Always confirm with the live tool above when you're scheduling a recurring meeting that spans a DST changeover.
Best Times to Meet
Inside the 7-hour overlap, the best slots depend on local culture. Seattle tends to favour mid-morning meetings; Chicago works 9am–6pm as a default. Aim for the middle of the window where neither side is just starting or wrapping up. Avoid Friday afternoons if the other party has a strong end-of-week culture, and skip lunchtime in whichever city is in the 12–2pm block.

Tips for Scheduling Across Seattle and Chicago
- Aim for around 12:30 PM Seattle time: the middle of the overlap leaves room for both sides if the call runs long.
- Both cities observe DST, but the changeover dates may differ. Check the offset around late March and late October each year.
- Watch Chicago's holiday calendar: Independence Day (07-04) takes most offices offline, so plan key meetings around it.
- Send each invite with both cities' local times in the description so neither party has to do the conversion mid-day.
- The gap is small enough that most teams keep one shared calendar in Los Angeles time and convert mentally.
Public Holidays and Working Weeks
USA runs a Monday–Friday working week with a standard public holiday calendar among the key closures. USA's major holidays include Independence Day (07-04) and Thanksgiving (fourth Thursday in November). Cross-check both calendars when scheduling recurring meetings: a 30-minute call in one city's holiday week typically gets a much lower attendance rate than the same slot a week later.
