Casino reservations, showtimes, and airport pickups all run on the same clock as Los Angeles. For travelers checking whether Las Vegas is on Pacific Time, the practical answer is yes, with one seasonal detail: the abbreviation changes between PST and PDT.
Las Vegas follows Pacific Time throughout the year. The city uses Pacific Standard Time during the colder months and Pacific Daylight Time while daylight saving time is active, so the UTC offset moves by one hour.
Las Vegas Pacific Time: What Changes Through The Year
Las Vegas remains in the Pacific Time Zone all year, but the city switches between two seasonal forms of Pacific Time. PST means UTC−8, while PDT means UTC−7.
- Pacific Standard Time: Used after the autumn clock change and through winter.
- Pacific Daylight Time: Used after the spring clock change and through most of spring, summer, and early fall.
- Pacific Time: The safest year-round label when the exact seasonal abbreviation is not needed.
Writing “PT” avoids a common scheduling error. Calling Las Vegas “PST” during summer is technically wrong because the city is then observing PDT.
How Las Vegas Compares With Other US Cities
Las Vegas matches California, Oregon, and Washington cities that follow Pacific Time. Most other major US cities are one to three hours ahead, while Alaska and Hawaii are behind.
| Place | Difference From Las Vegas | Planning Note |
|---|---|---|
| Los Angeles | Same time | Flights, calls, and events use an identical local clock. |
| San Francisco | Same time | No clock adjustment is needed in either direction. |
| Seattle | Same time | Both cities switch between PST and PDT on the same schedule. |
| Denver | 1 hour ahead | When it is 8:00 p.m. in Las Vegas, it is 9:00 p.m. in Denver. |
| Chicago | 2 hours ahead | An 8:00 p.m. Las Vegas show begins at 10:00 p.m. Chicago time. |
| New York City | 3 hours ahead | Noon in Las Vegas is 3:00 p.m. in New York. |
| Anchorage | 1 hour behind | Las Vegas is one hour ahead when both follow their normal seasonal clocks. |
| Phoenix | Same in much of spring through fall; 1 hour ahead in winter | Arizona generally does not change clocks, while Las Vegas does. |
| Honolulu | 2 or 3 hours behind | Hawaii stays on standard time, so the gap changes when Las Vegas changes clocks. |
Does Las Vegas Change Clocks?
Yes, Las Vegas normally moves clocks forward one hour in March and back one hour in November. Nevada still observes the federal daylight saving schedule.
The federal daylight saving statute sets the change for the second Sunday in March and the first Sunday in November. In 2026, Las Vegas moved to PDT on March 8 and returns to PST on November 1.
At the spring change, 2:00 a.m. becomes 3:00 a.m. At the autumn change, 2:00 a.m. returns to 1:00 a.m., creating a repeated hour that can affect overnight flights, hotel arrivals, and scheduled rides.
What To Set On Phones And Calendars
Travelers should leave automatic date and time enabled on phones, watches, and laptops. Most devices will switch to the correct Las Vegas offset after connecting to a local mobile or Wi-Fi network.
For a manual calendar setting, choose Las Vegas or the IANA zone America/Los_Angeles. Both follow the same Pacific Time rules, and using a named city zone is safer than entering a fixed UTC offset that will not change with daylight saving time.
- Set the event in Las Vegas local time.
- Attach the Las Vegas or America/Los_Angeles time zone.
- Check the attendee’s displayed time before sending.
- Recheck bookings that fall on a March or November clock-change weekend.
Scheduling tip: Casino showtimes, restaurant bookings, hotel check-in, and Harry Reid International Airport departures all use local Las Vegas time.
Where The Confusion Comes From
The confusion usually comes from mixing up Pacific Time, PST, and PDT. Pacific Time is the year-round zone name; PST and PDT describe which offset is active at a given point in the year.
Phoenix causes a second source of confusion. Las Vegas and Phoenix often display the same clock time during daylight saving months because Las Vegas is on UTC−7 and Phoenix remains on UTC−7, but the two cities use different zone rules. During Las Vegas winter, Phoenix is one hour ahead.
U.S. Department of Transportation records identify one limited Nevada exception outside the Las Vegas area: West Wendover follows Mountain Time. That border-city arrangement does not affect Las Vegas, Clark County, the Strip, Downtown Las Vegas, or Harry Reid International Airport.
Planning A Las Vegas Stay Around Local Time
Every major Las Vegas visitor area uses the same local time, including the Strip, Downtown, Henderson, Summerlin, and the airport. Hotel choice changes transfer time, not the clock.
A location map makes it easier to compare the Strip, Downtown, and off-Strip properties while keeping arrival plans tied to Las Vegas local time:
Late arrivals should check the hotel’s stated check-in policy and the final airport-transfer time in local Pacific Time. A booking confirmation sent from another time zone may display both the event zone and the viewer’s home zone, so the zone label matters as much as the hour.
Las Vegas Time At A Glance
Las Vegas uses Pacific Time, changes clocks with most of the United States, and stays synchronized with Los Angeles, San Francisco, and Seattle. The correct seasonal label depends on the date.
- Year-round zone: Pacific Time, abbreviated PT.
- Winter label: Pacific Standard Time, abbreviated PST, at UTC−8.
- Daylight label: Pacific Daylight Time, abbreviated PDT, at UTC−7.
- 2026 clock changes: March 8 and November 1.
- Phone setting: Automatic time, Las Vegas, or America/Los_Angeles.
- Same-time cities: Los Angeles, San Francisco, San Diego, Portland, and Seattle.
- Most common mistake: Writing PST for a summer event that actually occurs during PDT.
For travel plans, “Pacific Time” is the cleanest year-round wording. Use PST or PDT only when the season and exact UTC offset matter.
