California Pacific Time Zone: PST and PDT Explained
California operates on Pacific Time (PT), the westernmost of the four contiguous US time zones. Like most of the United States, California observes Daylight Saving Time, shifting between two offsets throughout the year:
Period | Abbreviation | UTC Offset | When Active |
|---|---|---|---|
Standard Time | PST (Pacific Standard Time) | UTC−8 | First Sunday of November → Second Sunday of March |
Daylight Saving Time | PDT (Pacific Daylight Time) | UTC−7 | Second Sunday of March → First Sunday of November |
California is the most populous US state, with approximately 39 million residents. Los Angeles alone is the second-largest US city by population. The Pacific Time Zone also encompasses Oregon, Washington, Nevada, and most of Idaho. Las Vegas, Seattle, Portland, San Francisco, San Jose, and Sacramento all share the same Pacific Time as Los Angeles.
One key geographic note: despite California being further west than the rest of the contiguous US, the Pacific Time Zone does not extend to Hawaii or Alaska. Hawaii is on its own Hawaii-Aleutian Time (UTC−10) with no DST. Alaska is UTC−9 (AKST) / UTC−8 (AKDT).
California is always 3 hours behind New York, regardless of the season, because both states observe DST on the same schedule. At any moment:
When it's 9:00 AM in Los Angeles, it's 12:00 PM (noon) in New York
When it's 12:00 PM in Los Angeles, it's 3:00 PM in New York
When it's 5:00 PM in Los Angeles, it's 8:00 PM in New York

California Time vs. Other US Zones and World Cities
The Pacific Time Zone sits at the western edge of the contiguous United States, making it the furthest-behind major US timezone. Understanding how Los Angeles time compares to both domestic and international cities is essential for anyone coordinating globally from the West Coast.
California (PDT, UTC−7) vs. US and world cities — Summer:
Location | UTC Offset (Summer) | Difference from LA (PDT) | LA time when it's 9 AM there |
|---|---|---|---|
New York, USA | UTC−4 (EDT) | +3 hours | 6:00 AM |
Chicago, USA | UTC−5 (CDT) | +2 hours | 7:00 AM |
Denver, USA | UTC−6 (MDT) | +1 hour | 8:00 AM |
Phoenix, USA | UTC−7 (MST, no DST) | same time | 9:00 AM |
Toronto, Canada | UTC−4 (EDT) | +3 hours | 6:00 AM |
London, UK | UTC+1 (BST) | +8 hours | 1:00 AM |
Paris, France | UTC+2 (CEST) | +9 hours | 12:00 AM midnight |
Dubai, UAE | UTC+4 | +11 hours | 10:00 PM (prev day) |
Mumbai, India | UTC+5:30 | +12.5 hours | 8:30 PM (prev day) |
Beijing, China | UTC+8 | +15 hours | 6:00 PM (prev day) |
Tokyo, Japan | UTC+9 | +16 hours | 5:00 PM (prev day) |
Sydney, Australia | UTC+10 (AEST) | +17 hours | 4:00 PM (prev day) |
California (PST, UTC−8) vs. key cities — Winter:
Location | UTC Offset (Winter) | Difference from LA (PST) |
|---|---|---|
New York | UTC−5 (EST) | +3 hours |
London | UTC+0 (GMT) | +8 hours |
Tokyo | UTC+9 (JST) | +17 hours |
Note that during winter (PST), Los Angeles is 17 hours behind Tokyo. This means that when it is Monday morning in Los Angeles, it is already Tuesday in Tokyo. Scheduling Asia-Pacific calls from California requires careful awareness of which day it is for your counterparts.
LA, New York, and London: Three-Way Time Comparison
Los Angeles, New York, and London form the backbone of global finance and media. Understanding how these three cities align throughout the day is critical for professionals in entertainment, finance, and tech.
Three-city schedule: LA (PDT) | NYC (EDT) | London (BST) — Summer:
Los Angeles (PDT) | New York (EDT) | London (BST) | Notes |
|---|---|---|---|
12:00 AM midnight | 3:00 AM | 8:00 AM | NYC pre-dawn, London morning |
2:00 AM | 5:00 AM | 10:00 AM | — |
5:00 AM | 8:00 AM | 1:00 PM | NYC morning commute |
6:00 AM | 9:00 AM | 2:00 PM | LA early risers, NYSE pre-open |
6:30 AM | 9:30 AM | 2:30 PM | NYSE opens |
8:00 AM | 11:00 AM | 4:00 PM | Prime LA–NYC–London working window |
9:00 AM | 12:00 PM | 5:00 PM | London end of standard day |
10:00 AM | 1:00 PM | 6:00 PM | London after work |
12:00 PM | 3:00 PM | 8:00 PM | NYC afternoon, London evening |
1:00 PM | 4:00 PM | 9:00 PM | NYSE closes |
3:00 PM | 6:00 PM | 11:00 PM | NYC end of day, London late night |
5:00 PM | 8:00 PM | 1:00 AM | London next day |
9:00 PM | 12:00 AM midnight | 5:00 AM | — |
The LA–NYC–London triple overlap is extremely narrow: roughly 6:30 AM–9:00 AM Pacific / 9:30 AM–12:00 PM Eastern / 2:30 PM–5:00 PM London. Outside this window, at least one city is either before work or after work hours.
For producers, agents, and executives managing talent in all three cities, the World Clock showing all three simultaneously is the most practical tool. The time in London page provides detailed LSE/FTSE trading times from a US perspective.
Hollywood and the Entertainment Industry Time Zone
Los Angeles is the global capital of film, television, streaming, and music. Unlike financial markets with fixed opening and closing times, the entertainment industry operates on flexible schedules — but Pacific Time drives all the important deadlines.
Key entertainment industry events in Pacific Time:
Event/Deadline | Pacific Time | Eastern Time | Notes |
|---|---|---|---|
Major studio pitch meetings | 9:00 AM – 12:00 PM PT | 12:00 PM – 3:00 PM ET | Mornings reserved for pitches |
Network TV primetime (East Coast feed) | 6:00 PM – 9:00 PM PT | 9:00 PM – 12:00 AM ET | 3-hour delay to West Coast |
Network TV primetime (West Coast feed) | 9:00 PM – 12:00 AM PT | 12:00 AM – 3:00 AM ET | Same shows, 3 hours later |
Award show air times (East Coast live) | 5:00 PM – 8:00 PM PT | 8:00 PM – 11:00 PM ET | Oscars, Emmys, Grammys |
Streaming platform midnight release (Netflix) | 12:00 AM PT | 3:00 AM ET | Netflix drops new content at midnight PT |
Box office tracking reports | 9:00 AM PT Friday | 12:00 PM ET Friday | Weekend projections |
Film industry curfew awareness: Los Angeles has municipal noise ordinances that affect outdoor filming. Permitted hours for most residential areas are 7:00 AM–10:00 PM PT. Productions in commercial zones have more flexibility.
Global premiere time zones: When a film premieres at a Los Angeles event at 7:00 PM PT, it is 10:00 PM in New York and 3:00 AM the next morning in London. UK entertainment journalists covering LA premieres must either stay up late or rely on wire reports.
Major Hollywood studios — Disney/Pixar (Burbank/Emeryville), Warner Bros. (Burbank), Universal (Universal City), Paramount (Hollywood), Sony Pictures (Culver City) — all operate on Pacific Time. Their international distribution offices in New York, London, and Tokyo coordinate around LA time for release scheduling.
Silicon Valley: Tech Company Global Operations from Pacific Time
Silicon Valley — spanning San Jose, Santa Clara, Menlo Park, Mountain View, Palo Alto, and San Francisco — is the world's tech capital, and it runs on Pacific Time. This creates a unique global scheduling challenge: the most important tech companies on earth start their workdays when much of the world is already winding down.
Major Silicon Valley tech company HQ locations (all Pacific Time):
Apple: Cupertino, CA
Google / Alphabet: Mountain View, CA
Meta: Menlo Park, CA
Netflix: Los Gatos, CA
Tesla: Austin, TX (moved from Palo Alto, now Central Time)
Salesforce: San Francisco, CA
Oracle: Austin, TX (moved, now Central Time)
Intel: Santa Clara, CA
Overlap windows: Silicon Valley engineering teams vs. global offices:
SV Time (PDT) | NYC Office (EDT) | London Office (BST) | Bangalore Office (IST, UTC+5:30) | Tokyo Office (JST) |
|---|---|---|---|---|
6:00 AM | 9:00 AM | 2:00 PM | 6:30 PM | 10:00 PM |
8:00 AM | 11:00 AM | 4:00 PM | 8:30 PM | 12:00 AM |
9:00 AM | 12:00 PM | 5:00 PM | 9:30 PM | 1:00 AM |
5:00 PM | 8:00 PM | 1:00 AM | 5:30 AM next day | 9:00 AM next day |
The Silicon Valley–Bangalore corridor is heavily used by tech companies for engineering overlap. The window where Bangalore engineers and SV engineers are both in their standard work day is extremely small — roughly SV 6:00–7:30 AM overlapping with Bangalore 6:30–8:00 PM. Many tech companies have adapted by creating staggered shifts and asynchronous communication-first cultures.
For teams tracking multiple time zones, the World Clock displays all zones simultaneously. The New York time page is essential for West Coast companies with East Coast offices or investors on Wall Street.
