UTC Offset: UTC-8
What is UTC-8?
UTC-8 is a fixed offset from Coordinated Universal Time: clocks on this offset are always 8 hours behind UTC. Unlike a named time zone, a UTC offset never shifts for daylight saving time. Regions that observe DST alternate between two different UTC offsets across the year, which is why the countries listed below can change with the seasons.
In aviation, shipping, and military usage, UTC-8 corresponds to the Uniform time zone (U), written with the letter suffix U in Zulu notation. Pilots and NATO forces use these letter zones so an order like "0800U" is unambiguous worldwide.
UTC-8 vs GMT-8
On a wall clock, UTC-8 and GMT-8 show the same time. The difference is in what they refer to: UTC is the modern standard kept by atomic clocks and used in computing, aviation, and science, while GMT is the older convention based on mean solar time at Greenwich. Technical systems, logs, and APIs should reference UTC-8.

UTC-8: The Pacific Standard Time Offset
UTC-8 is a fixed time offset that places clocks 8 hours behind Coordinated Universal Time (UTC). Unlike a named time zone such as Pacific Standard Time (PST), which includes daylight saving time (DST) rules, UTC-8 is a constant reference. When regions in the Pacific time zone observe DST, they shift to UTC-7, leaving UTC-8 only for standard time. This article explores what UTC-8 means, which regions use it, and practical scheduling tips.
Fixed Offset vs. Named Time Zone
A fixed UTC offset like UTC-8 is simply a number of hours behind UTC. It never changes. In contrast, a named time zone like America/Los_Angeles follows a set of rules, including when to spring forward or fall back for DST. For example, Los Angeles uses UTC-8 during winter (PST) and UTC-7 during summer (PDT). So UTC-8 is only half the story for many locations. The IANA time zone database lists zones at their standard offset, but during DST they deviate. This article focuses on the standard offset UTC-8.
Regions and Cities on UTC-8
UTC-8 is observed as standard time in several regions across North America and the Pacific. Key areas include:
- United States: The entire state of California, most of Oregon and Washington, and parts of Idaho and Nevada. Major cities: Los Angeles, San Francisco, Seattle, Portland, Las Vegas (Nevada uses UTC-8 standard time).
- Canada: British Columbia (most of the province), Yukon (though Yukon is considering a change). Key cities: Vancouver, Victoria.
- Mexico: The state of Baja California (northern part). Major city: Tijuana, Mexicali.
- Pitcairn Islands: A British Overseas Territory in the Pacific, Pitcairn uses UTC-8 year-round, no DST. The only inhabited island is Pitcairn Island (population about 50).
Note that during DST, these regions shift to UTC-7, so UTC-8 is not observed there in summer. Only Pitcairn stays on UTC-8 all year.
Practical Scheduling Notes
When scheduling across UTC-8, remember that most locations using this offset observe DST. From March to November, they are on UTC-7. So a meeting at 10:00 AM UTC-8 in winter is 11:00 AM UTC-7 in summer. Pitcairn is the exception, remaining on UTC-8 year-round. Military time uses the letter "U" for UTC-8 (Uniform time zone). In casual use, UTC and GMT are often interchanged, but GMT is a time zone (used in UK) while UTC is a standard. On a clock, both read the same: UTC-8 is 8 hours behind UTC/GMT.
Countries and Territories Using UTC-8
The list of countries on UTC-8 is not static because DST regions move on and off this offset. Currently, the following countries have regions that use UTC-8 as standard time:
- Canada (British Columbia, Yukon)
- Mexico (Baja California)
- Pitcairn Islands (year-round)
- United States (California, Oregon, Washington, Nevada, Idaho panhandle)
During summer, these regions switch to UTC-7, so UTC-8 is only observed in winter. Pitcairn remains constant.
IANA Time Zones at UTC-8
The IANA time zone database includes several zones that use UTC-8 as their standard offset. These are:
- America/Los_Angeles
- America/Tijuana
- America/Vancouver
- Canada/Pacific (alias for America/Vancouver)
- Pacific/Pitcairn
- US/Pacific (alias for America/Los_Angeles)
These zones follow DST rules except Pacific/Pitcairn, which stays on UTC-8 all year.
Frequently Asked Questions
What is the difference between UTC-8 and PST?
UTC-8 is a fixed offset 8 hours behind UTC. PST (Pacific Standard Time) is a time zone that uses UTC-8 during standard time, but switches to UTC-7 during daylight saving time. So PST is not constant; UTC-8 is.
Which major cities are in UTC-8?
Major cities in UTC-8 include Los Angeles, San Francisco, Seattle, Portland, Vancouver, Tijuana, and Las Vegas. Note that these cities observe DST and are on UTC-7 in summer.
Does any place stay on UTC-8 all year?
Yes, the Pitcairn Islands use UTC-8 year-round with no daylight saving time. Also, some uninhabited areas like the Clipperton Island use UTC-8 permanently.
What is the military letter for UTC-8?
The military time zone letter for UTC-8 is 'U' (Uniform time zone). It is used in aviation and military operations.
Is UTC-8 the same as GMT-8?
Yes, on a clock, UTC-8 and GMT-8 show the same time. However, GMT is a time zone (used in the UK) while UTC is a time standard. For practical purposes, they are interchangeable when referring to offsets.
