Your Chicago calendar says the demo starts at 11 a.m., and someone in Los Angeles wants to know whether that means 9 a.m. their time. It does. Central runs exactly two hours ahead of Pacific, and unlike transatlantic pairs, that gap never drifts: both zones spring forward and fall back on the same Sundays, so 11 a.m. Central is 9 a.m. Pacific in January and in July alike. The clocks above show both cities at this second, the converter resolves any date, and the chart lays out all 24 hours.
What People Convert CST to PST For
Standups between Texas, Chicago, and California
An Austin team that opens its daily standup at 9 a.m. is asking San Francisco to show up at 7 a.m. — early, but survivable. Push it to 10 a.m. Central and California gets 8 a.m., which most engineers accept without complaint. The genuinely shared window — the one an Austin or Chicago manager can book without apologizing — runs 10 a.m. to 5 p.m. Central, or 8 a.m. to 3 p.m. Pacific, and it holds every week of the year.
Market hours for Chicago desks and West Coast clients
The NYSE regular session runs 8:30 a.m. to 3 p.m. Central, which is 6:30 a.m. to 1 p.m. Pacific. A Los Angeles client who calls at 9 a.m. their time has already missed two and a half hours of trading. The monthly CPI release lands at 7:30 a.m. Central, meaning 5:30 a.m. in California, which is why West Coast analysts set alarms rather than calendar reminders.
Live sports, awards shows, and Central time listings
Networks advertise prime time as 8/7c — 8 p.m. Eastern, 7 p.m. Central — and West Coast stations usually delay the feed so it still starts at 8 p.m. locally. Live events do not work that way. A kickoff listed at 7:20 p.m. Central actually starts at 5:20 p.m. Pacific, dinnertime in California, and an awards show that opens at 7 p.m. Central is already on West Coast screens at 5 p.m., with the red carpet running earlier still.
Support handoffs and on-call rotations
A Dallas support desk that closes at 6 p.m. Central goes dark at 4 p.m. Pacific, leaving West Coast customers with unanswered tickets before the evening rotation picks up. Teams running follow-the-sun coverage stagger the shifts instead: Central works 8 a.m. to 5 p.m. on its own clock, Pacific does the same on theirs, and the overlap comes to a clean seven hours.
Flights from Chicago and Dallas to the West Coast
Itineraries print every time in the airport's local zone, which makes westbound flights look impossibly short. Leave O'Hare at 9 a.m. Central and you land at LAX around 11:30 a.m. Pacific: the clock advanced two and a half hours, but you sat on the plane for four and a half. Convert the pickup time separately so whoever is at the curb is reading the same clock you are.
Deadlines, filings, and application cutoffs
A Chicago employer posting an 11:59 p.m. Central deadline is really giving Californians until 9:59 p.m. Pacific, not the near-midnight cushion the wording suggests. The same trap catches university applications, grant portals, and bid submissions, because the server enforces the zone that was stated. Check the converter before assuming you have two more hours than the deadline actually allows.
Calls with family and friends across the two zones
A grandparent in San Antonio ringing at 8 p.m. Central reaches Los Angeles at 6 p.m., squarely in the middle of dinner. Reverse it: a 9 p.m. call from Pacific arrives in Texas at 11 p.m., well past bedtime for anyone with school in the morning. The two live clocks settle the courtesy question faster than counting on your fingers.
How the Conversion Works
The page never simply adds two hours. It asks the browser's IANA timezone database for the real offset of America/Chicago and America/Los_Angeles at the exact instant you pick. Chicago reports CST at UTC−6 or CDT at UTC−5; Los Angeles reports PST at UTC−8 or PDT at UTC−7. Because both zones change on the same Sundays, the arithmetic almost always resolves to two hours — but it is computed per date rather than assumed, so even the changeover mornings come out right. Everything runs in your browser, and nothing you type is transmitted.
Frequently Asked Questions
Is CST always 2 hours ahead of PST?
For every practical purpose, yes. Central and Pacific are both US zones, and they start and end daylight saving on the same Sundays at the same local hour, so the two-hour gap survives the clock changes intact. That is unusual — most long-distance pairs drift by an hour twice a year. The only exception is a short overnight window on the two changeover Sundays themselves, described below.
What is 11 a.m. CST in PST?
9 a.m. Pacific. Subtract two hours going from Central to Pacific, and add two coming back. It works the same in January and July: 9 a.m. Central is 7 a.m. Pacific, noon Central is 10 a.m. Pacific, and 5 p.m. Central is 3 p.m. Pacific. The chart above lays out all 24 hours if you would rather not do the arithmetic yourself.
What is the difference between CST and CDT, or PST and PDT?
CST is Central Standard Time at UTC−6, while CDT is Central Daylight Time at UTC−5. PST is Pacific Standard Time at UTC−8, while PDT is Pacific Daylight Time at UTC−7. Most people say CST to PST year-round, but from March to November the zones are technically CDT and PDT. The two-hour difference is identical either way, so the loose usage rarely causes trouble.
When do Central and Pacific change their clocks?
Both switch on the second Sunday in March and the first Sunday in November, at 2 a.m. local time in each zone. That means March 8 and November 1 in 2026, then March 14 and November 7 in 2027. Because the rule is word-for-word identical in both zones, the two-hour gap is restored as soon as each one has finished changing.
Does the two-hour gap ever break?
Only for two hours on each changeover Sunday — four hours a year, all of it overnight. Each zone changes at 2 a.m. by its own clock, and Central always gets there first. On March 8, 2026, Chicago jumps to 3 a.m. CDT while Los Angeles is still sitting at midnight, a three-hour gap that lasts until California reaches its own 2 a.m. two hours later. On November 1, 2026, Chicago falls back first, so the gap narrows to one hour for the same two-hour stretch.
Which places use Central and Pacific time?
Central covers Chicago, Houston, Dallas, Austin, San Antonio, Minneapolis, New Orleans, Memphis, and Kansas City, along with most of Texas and all of Illinois. Pacific covers Los Angeles, San Francisco, San Diego, Seattle, Portland, Las Vegas, and Sacramento — all of California and Washington, plus nearly all of Nevada and Oregon. Arizona is the odd neighbor: outside the Navajo Nation it stays on Mountain Standard Time year-round, which puts Phoenix on the same clock as Los Angeles from March to November and an hour ahead of it the rest of the year.
