Las Vegas runs on Pacific Time, full stop

Las Vegas sits in the America/Los_Angeles time zone. Same zone as Los Angeles, San Francisco, Seattle, and all of California. Nevada does not have its own time zone, and it never has. If you know the time in Los Angeles, you know the time in Las Vegas.

What changes is whether the city is on Pacific Standard Time (PST, UTC-8) or Pacific Daylight Time (PDT, UTC-7). That depends on the date.

From the second Sunday of March to the first Sunday of November, Las Vegas is on PDT, UTC-7. From the first Sunday of November to the second Sunday of March, it is on PST, UTC-8.

When do Las Vegas clocks spring forward and fall back?

These are the exact dates for the next two years.

  • 8 March 2026: clocks spring forward at 02:00 local. PST becomes PDT. You lose one hour.
  • 1 November 2026: clocks fall back at 02:00 local. PDT becomes PST. You gain one hour.
  • 14 March 2027: clocks spring forward again.
  • 7 November 2027: clocks fall back again.

The transition happens at the same moment across all of Pacific Time. If you are scheduling a call that straddles one of these dates, the offset difference is one hour. A 10:00 meeting in Las Vegas on 7 November is at 10:00 PST (UTC-8). On 8 November it is at 10:00 PST (UTC-8) too, because the change already happened. The confusion is for people who forget the switch happened at all.

Why Las Vegas is always 3 hours behind New York

Las Vegas is 3 hours behind New York, 2 hours behind Chicago, and 1 hour behind Denver. Those differences do not change when the clocks move, because all those cities observe daylight saving time on the same schedule.

If your New York team starts work at 09:00 Eastern, it is 06:00 in Las Vegas. If they finish at 17:00 Eastern, it is 14:00 in Las Vegas. You have a solid 5-hour window for calls: 09:00 to 14:00 Las Vegas time, which is 12:00 to 17:00 New York time.

The golden hour for a US-wide call is 11:00 Las Vegas time, which is 14:00 New York time. That is when the West Coast has been working for two hours and the East Coast still has three hours left in the day.

Why London stays 8 hours ahead of Las Vegas

On 15 January 2026, Las Vegas is on PST (UTC-8) and London is on GMT (UTC+0). The difference is 8 hours.

On 15 July 2026, Las Vegas is on PDT (UTC-7) and London is on BST (UTC+1). The difference is still 8 hours.

London and Las Vegas move their clocks on different weekends. The UK usually springs forward in late March and falls back in late October, while the US does it in March and November. That creates a brief period in March and a brief period in October and November where the gap is 7 hours. But for almost the entire year, the gap is 8 hours. Do not plan your recurring meeting around the exception.

An 8-hour gap means that 09:00 Las Vegas is 17:00 London. That is the end of the London work day. A London team that starts at 09:00 is at 01:00 Las Vegas. The only overlap for a live call is 15:00 to 17:00 London time, which is 07:00 to 09:00 Las Vegas time. That works if the Las Vegas side is willing to start early.

How Paris, Berlin, and Dubai shift against Las Vegas

Paris and Berlin are 9 hours ahead of Las Vegas in both summer and winter, with the same caveat about the transition weeks. Dubai is 11 hours ahead in summer, 12 hours ahead in winter. Dubai does not observe daylight saving time, so the gap actually changes.

On 15 January 2026 (PST), Dubai is 12 hours ahead. On 15 July 2026 (PDT), Dubai is 11 hours ahead. That one-hour shift matters if you are scheduling a weekly call.

The practical result: a 10:00 Las Vegas morning call is 22:00 Dubai in winter, 21:00 Dubai in summer. That is after the Dubai work day ends. A 14:00 Las Vegas call is 02:00 Dubai the next day. To reach Dubai during its working hours (roughly 08:00 to 17:00), you need to call Las Vegas between 20:00 and 05:00 the next day. That is not realistic for most teams. The solution is asynchronous communication: record the meeting, send the recording, and let the Dubai team watch it the next morning.

Why Asia and Australia calls mean overnight for Las Vegas

Mumbai is 13.5 hours ahead of Las Vegas in winter, 12.5 hours ahead in summer. Singapore is 16 hours ahead in winter, 15 hours ahead in summer. Tokyo is 17 hours ahead in winter, 16 hours ahead in summer. Sydney is 19 hours ahead in winter, 17 hours ahead in summer.

None of these produce a working-hours overlap. A 10:00 Las Vegas call is 23:00 Mumbai, 02:00 Singapore (next day), 03:00 Tokyo (next day), and 05:00 Sydney (next day). The only way to get a live connection is to schedule the call at the very end of the Las Vegas work day and the very start of the Asian work day, or vice versa.

The best compromise for Tokyo: 16:00 Las Vegas is 09:00 Tokyo the next morning in winter, 08:00 in summer. That works if the Las Vegas side is willing to stay late and the Tokyo side is willing to start early.

For Sydney, 15:00 Las Vegas is 10:00 Sydney the next morning in winter. In summer, 16:00 Las Vegas is 09:00 Sydney.

Sunrise and sunset times matter for schedule design

If you are asking a team to start a call at 07:00 Las Vegas, check the sunrise time first.

On 21 June 2026, the June solstice, sunrise in Las Vegas is 05:23. A 07:00 call is after sunrise, and the sun has been up for nearly two hours. That is fine.

On 21 December 2026, the December solstice, sunrise is 06:47 and sunset is 16:29. A 07:00 call is just after sunrise. A 16:30 call is after sunset. If you schedule a call for 17:00 in December, the sun set over an hour ago, and the mood is different.

The daylight hours swing from 9 hours 42 minutes in December to 14 hours 37 minutes in June. Plan your early-morning and late-afternoon calls around the season, not just the clock.

How to confirm the Las Vegas time offset when you are not sure

Use the IANA time zone identifier America/Los_Angeles in your calendar software. That is the only identifier that handles daylight saving time correctly for Las Vegas. Do not use "PST" or "PDT" as a static label, because the software will not know which one applies on a given date.

Most calendar tools, including Google Calendar, Outlook, and Apple Calendar, accept America/Los_Angeles directly. If your system does not, use "Pacific Time" as the label. That is the umbrella term that covers both PST and PDT.

What conference planners need to know about the 14 March 2027 clock change

The next clock change after the one in November 2026 is 14 March 2027 at 02:00 local. Las Vegas springs forward to PDT (UTC-7). If you are planning a conference in Las Vegas in early March 2027, the city will still be on PST. If you are planning for late March, it will be on PDT.

That one-hour shift affects every international call you make. A team in London that was 8 hours ahead becomes 8 hours ahead again (the UK will have already moved its clocks by then). A team in Dubai that was 12 hours ahead becomes 11 hours ahead. If you have a regular weekly call with Dubai, you need to adjust the time by one hour in March.

Mark the date now. Set a reminder for the week before 14 March 2027. Update your recurring meeting invitations to reflect the new offset. Then do the same for the fall back on 7 November 2027.
