Background
Interpretation and common distinctions.
Current time in Los Angeles, California
This page shows a live local clock for Los Angeles, using the IANA zone America/Los_Angeles. Time is read from your browser with that zone applied — the same Pacific Time used across California and much of the U.S. West Coast.
This site’s legacy California, PST, and PDT URLs also point here.
Pacific Time (PST / PDT)
| Season | Name | Abbreviation | UTC offset |
|---|---|---|---|
| Winter (standard) | Pacific Standard Time | PST | UTC−8 |
| Summer (daylight) | Pacific Daylight Time | PDT | UTC−7 |
Together these are often labeled Pacific Time (PT). Prefer UTC offsets or the IANA id when accuracy matters.
Daylight Saving Time
Los Angeles observes U.S. Daylight Saving Time:
- Spring forward — second Sunday in March at 02:00 PST → 03:00 PDT (UTC−8 → UTC−7).
- Fall back — first Sunday in November at 02:00 PDT → 01:00 PST (UTC−7 → UTC−8).
For 2026, Los Angeles moved to PDT on 8 March and returns to PST on 1 November. Hawaii and most of Arizona (Phoenix) do not observe DST.
How Pacific Time compares
When both sides share the same DST status:
- Mountain Time (Denver): Los Angeles is 1 hour behind.
- Central Time (Chicago): Los Angeles is 2 hours behind.
- Eastern Time (New York): Los Angeles is 3 hours behind.
- Alaska Time (Anchorage): Los Angeles is 1 hour ahead.
- UTC: Los Angeles is 8 hours behind in winter, 7 hours behind in summer.
Versus year-round zones:
- Phoenix (MST, UTC−7): Phoenix is 1 hour ahead in winter; same time in summer.
- Hawaii (HST, UTC−10): Los Angeles is 2 hours ahead in winter, 3 hours ahead in summer.
UTC vs GMT
For everyday scheduling, UTC and GMT both mean offset +0. Example: noon UTC is 04:00 PST or 05:00 PDT.

Frequently asked questions
Key distinctions behind the calculation.
What time zone is Los Angeles in?
Los Angeles uses Pacific Time. The IANA identifier is America/Los_Angeles. Winter is PST (UTC−8); summer daylight time is PDT (UTC−7).
What is the difference between PST and PDT?
PST (Pacific Standard Time) is UTC−8 and is used in winter. PDT (Pacific Daylight Time) is UTC−7 and is used when Daylight Saving Time is in effect. Together they are often called Pacific Time (PT).
Does Los Angeles observe Daylight Saving Time?
Yes. Clocks spring forward on the second Sunday in March (02:00 PST → 03:00 PDT) and fall back on the first Sunday in November (02:00 PDT → 01:00 PST).
Is all of California on Pacific Time?
Yes. California uses Pacific Time statewide. This site’s legacy California / PST / PDT URLs also point here.
How does Los Angeles compare to Phoenix?
Phoenix stays on MST (UTC−7) year-round. In winter Los Angeles is on PST (UTC−8), so Phoenix is 1 hour ahead. In summer Los Angeles is on PDT (UTC−7), so both cities show the same clock time.
How does Los Angeles compare to New York?
Pacific Time is three hours behind Eastern Time whenever both regions share the same DST status.
Why use America/Los_Angeles instead of “PST”?
IANA zone IDs encode the correct offset and DST rules. This clock uses America/Los_Angeles so the browser applies the official transition table.
What is UTC?
Coordinated Universal Time (UTC) is the global time standard. Los Angeles is UTC−8 in winter and UTC−7 in summer.
