PST vs UTC Time Difference
See how Pacific Standard Time compares with Coordinated Universal Time, including the current hour gap, DST changes, and practical meeting windows.
PST and UTC Offset
Pacific Standard Time is UTC-8 while Coordinated Universal Time is UTC+0, making UTC 8 hours ahead of PST during standard time.
DST Changes the Gap
Pacific Standard Time regions may switch to daylight saving time, which changes the difference from UTC-8 to UTC-7 seasonally. UTC does not observe DST.

This is useful when you are planning a call between teams on the west coast of the United States, Canada, or Mexico and colleagues who schedule in UTC for aviation, infrastructure, cloud operations, or international project management.Add comparison cities: Click + Add City and add places that commonly work alongside Pacific Standard Time or UTC, such as Los Angeles, Vancouver, Mexico City, or London depending on your workflow. This helps remote software teams, logistics coordinators, and support organizations compare Pacific Standard Time business hours with UTC-based schedules used in monitoring dashboards, server logs, and globally distributed calendars.
Select a time range on the grid: Click Select, then drag across the Pacific Standard Time row to highlight a working window in purple; you can resize it with the left and right handles or drag the center to shift the whole block. For example, dragging from 9:00 PST to 12:00 PST shows 17:00 UTC to 20:00 UTC, which is a practical overlap for a west coast morning meeting, a deployment window, or a handoff from a Pacific Standard Time operations team to a UTC-based global support rotation.
Export and share the schedule: After selecting the range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially useful when a product manager needs to send a Pacific Standard Time meeting slot to a UTC-based engineering team so every participant receives the event in their own calendar system without manually converting 15:00 PST = 23:00 UTC or 18:00 PST = 2:00 UTC (next day).
PST vs UTC Offset Explained
Pacific Standard Time (Pacific Standard Time, UTC-8) is 8 hours behind Coordinated Universal Time (UTC+0), and UTC is 8 hours ahead of PST. In practical terms, when it is 9:00 PST, it is 17:00 UTC, and when it is 12:00 PST, it is 20:00 UTC. This gap matters for scheduling west coast business hours against international teams that use UTC as a neutral reference.
Pacific Standard Time is a standard-time abbreviation, and its daylight saving counterpart is PDT. Coordinated Universal Time does not observe daylight saving time, so UTC stays fixed all year while Pacific timekeeping can shift seasonally away from PST when daylight time is in effect. That distinction is important for recurring meetings, cloud maintenance windows, and customer support coverage, because a meeting defined in Pacific Standard Time is not the same as one defined in the broader Pacific time region during daylight saving periods.
PST is used in Canada, Mexico, and the United States, making it relevant for cross-border retail, media, software, shipping, and customer support teams operating on the Pacific side of North America. UTC is widely used as the baseline for global coordination in fields such as aviation, data centers, cybersecurity, and international engineering, where a fixed non-DST reference reduces ambiguity. If your team works from Pacific Standard Time while your incident logs, cron schedules, or vendor SLAs are written in UTC, the 8-hour difference is the key number to keep in view.
Common PST to UTC Scheduling Examples
Pacific Standard Time (Pacific Standard Time, UTC-8) maps cleanly to Coordinated Universal Time using the same 8-hour difference across this comparison. The most common workday examples are 9:00 PST = 17:00 UTC, 12:00 PST = 20:00 UTC, and 15:00 PST = 23:00 UTC. These are useful reference points for planning standups, release approvals, and client meetings that start during a west coast workday and need to be communicated in UTC.
Late-day scheduling needs extra attention because the UTC date can roll over to the next day. For example, 18:00 PST = 2:00 UTC (next day), which affects overnight maintenance, international flight operations, and after-hours support escalations. If a California-based operations team schedules an evening task in Pacific Standard Time, a UTC-based team will often see that task on the following calendar date.
Because UTC does not change for daylight saving time, many global organizations prefer to publish deadlines, release windows, and incident timelines in UTC first. Pacific Standard Time is still convenient for local teams in the western parts of Canada, Mexico, and the United States, but publishing both references prevents confusion. A release note that says 12:00 PST / 20:00 UTC is much clearer for distributed teams than listing only one time zone.
Frequently Asked Questions
What is the time difference between PST and UTC?
Pacific Standard Time is 8 hours behind Coordinated Universal Time, and UTC is 8 hours ahead of PST. A simple example is 9:00 PST = 17:00 UTC, which makes UTC a common reference for international calendars, server timestamps, and cross-border business communication.
Is UTC always 8 hours ahead of Pacific Standard Time?
Yes, when you are specifically comparing Pacific Standard Time (UTC-8) with Coordinated Universal Time (UTC+0), the difference is 8 hours. For example, 15:00 PST = 23:00 UTC, which is why west coast afternoon meetings often land late in the UTC evening.
Does UTC observe daylight saving time like Pacific Standard Time?
Coordinated Universal Time does not observe daylight saving time, so it remains fixed at UTC+0 throughout the year. Pacific Standard Time is the standard-time form of Pacific time, and its daylight saving counterpart is PDT, so seasonal schedule changes on the Pacific side can affect recurring meetings if they are not defined carefully.
How do I convert 12 PM PST to UTC?
12:00 PST = 20:00 UTC. This conversion is commonly used for publishing webinar times, software deployment windows, and international support handoffs where a noon Pacific Standard Time event needs a single global reference.
Why does 6 PM PST become 2 AM UTC the next day?
Because UTC is 8 hours ahead of Pacific Standard Time, evening times in PST can cross midnight in UTC. That is why 18:00 PST = 2:00 UTC (next day), which is especially important for overnight maintenance notices, deadline cutoffs, and any event where the calendar date matters as much as the hour.
Is PST Pacific Standard Time or Pitcairn Standard Time?
On this page, PST means Pacific Standard Time (UTC-8). PST can also mean Pitcairn Standard Time (UTC-8), and if you need that meaning, use /time-converter/pst-pitcairn-time-zone to avoid mixing two different regional interpretations of the same abbreviation.
Which countries use Pacific Standard Time?
Pacific Standard Time is used in Canada, Mexico, and the United States. That makes PST relevant for west coast business operations, cross-border trade, customer service coverage, and travel planning across North America, especially when those schedules must also be shared in UTC for international partners.
