CST vs PST time zone comparison

How CST and PST compare

Pacific Standard Time runs two hours behind Central Standard Time, a moderate gap that is easy to handle if you remember which direction you are converting. Chicago, Dallas, Houston, Minneapolis, and Mexico City sit on CST. Los Angeles, San Francisco, Seattle, and Vancouver sit on PST. A 9 AM Central meeting is 7 AM Pacific, which is too early for most West Coast professionals. A 5 PM Pacific call is 7 PM Central, which is too late for most Central attendees. The practical sweet spot for cross-zone meetings is the late morning Central window: 11 AM Central is 9 AM Pacific, both sides have started, neither side has earned their lunch break, and there is a clear runway to do real work. Both zones observe daylight saving on the same dates (second Sunday of March, first Sunday of November), so the two-hour offset never moves. Watch out for Arizona, which is nominally on MST (UTC-7) and does not observe DST, so a Phoenix contact will sit at one hour behind CST in summer and two hours behind CST in winter — switching their effective relationship with both Chicago and Los Angeles twice a year.

Working-hour overlap

Reliable overlap from 11 AM to 3 PM Central (9 AM to 1 PM Pacific), with 11 AM Central the default for routine cross-zone calls.

When to schedule

Default to 11 AM Central (9 AM Pacific) for cross-zone meetings. Both sides have arrived, neither side is rushed, and lunch sits clearly ahead. The wider sensible window is 11 AM to 3 PM Central (9 AM to 1 PM Pacific). For longer working sessions, anchor the start to 10 AM Pacific (12 PM Central) so the West Coast gets a full hour of warm-up time before the call. Never schedule recurring weekly meetings for 9 AM Central (7 AM Pacific) — this works for one-off urgent calls but not as a sustained weekly cadence.

Notable context

Chicago's CME and CBOE derivative markets open at 8:30 AM Central (6:30 AM Pacific), which means Chicago commodities desks are operating before most California tech teams have brushed their teeth. The film and television industry centered in Los Angeles runs on a much later daily schedule, with many production-side calls happening from 11 AM Pacific (1 PM Central) onward and pushing well past 6 PM Pacific. If you are coordinating between Chicago finance and LA entertainment, the practical overlap window collapses to 11 AM Central to 1 PM Central, which is 9 AM to 11 AM Pacific — narrow but usable.
