Pacific Time (PT)
Las Vegas operates on Pacific Time (PT). Las Vegas observes Daylight Saving Time, springing forward one hour in March and falling back in November. During DST, the abbreviation changes to reflect the shift.
Time Zone: Pacific Time (PT) — Standard Offset: UTC-8 (PST) — DST Offset: UTC-7 (PDT)
Country: United States
This city observes Daylight Saving Time, so the UTC offset changes twice per year. Always verify the current offset when scheduling across time zones.
Las Vegas operates on Pacific Time, the same as Los Angeles. The city's entertainment, convention, and hospitality industries mean events are scheduled for PT audiences worldwide. CES (the world's largest consumer electronics show), held every January, runs on Pacific Time and draws over 100,000 international attendees who must convert their schedules to PT.
Las Vegas hosts more major conventions than any other US city — the Las Vegas Convention Center is one of the largest in the world. Trade shows run on Pacific Time, meaning attendees from the East Coast lose 3 hours (a 9 AM PT opening is noon ET) and international visitors face larger gaps. Convention schedules are designed with this in mind, typically running 9 AM to 5 PM PT to capture the widest domestic audience.
Nevada observes DST from the second Sunday in March through the first Sunday in November. This puts Las Vegas on the same time as Los Angeles year-round. The nearby Arizona border (which doesn't observe DST) means a short drive east can change your effective time zone during summer months. The Nevada-Arizona border area can be confusing for scheduling.
Las Vegas's tourist economy means the city essentially operates around the clock — casinos never close, and many restaurants and entertainment venues run late-night hours. But business operations, convention schedules, and hotel check-in/check-out times follow standard Pacific Time. International tourists should note that Las Vegas is 8 hours behind London (7 during BST) and 17 hours behind Tokyo (16 during PDT).
