About CST to PST Time
CST covers Chicago, Dallas, Houston, Mexico City and Winnipeg. PST covers Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver.
Working days overlap between 11:00 and 18:00 CST, which is 09:00–16:00 in PST. That window is where calls land without anyone working late.
Both regions use daylight saving, so the gap holds for most of the year — except for the week or two each spring and autumn when they switch on different dates.
How it works
Pacific Time (Los Angeles) is always 2 hours behind of Central Time (Chicago).
- Take the CST time you want to convert.
- Subtract 2 hours.
- Roll the date forward or back if the result crosses midnight.
Neither side changes its clocks relative to the other, so this gap holds all year.
Zone details: CST is −6 in winter and −5 in summer (UTC), PST is −8 in winter and −7 in summer.
