Convert PST to UTC
See the exact PST to UTC time difference, compare hours side by side, and schedule meetings with calendar-ready export options.
How PST Converts
PST is Pacific Standard Time at UTC-8, so converting to UTC means adding 8 hours. This converter shows the exact offset difference and updates results instantly for selected times.

How to Convert PST to UTC
Open the PST to UTC converter: Go to https://www.xconvert.com/time-converter/pst-to-utc-converter. The page loads with PST and UTC already set up in the comparison grid, which is useful when you need to line up a support handoff, cloud maintenance window, or client call between teams working on Pacific time and systems scheduled in Coordinated Universal Time.
Add comparison cities if your workflow includes regional teams: Click + Add City and search for cities that commonly work alongside PST or UTC schedules, such as Los Angeles for West Coast operations, London for international business coordination, or Manila for outsourced support and back-office work. This helps when a software team, trading desk, or customer success group needs to see PST against UTC while also keeping local office hours visible in the same grid.
Select the time range on the grid: Click Select, then drag across the PST row to highlight a working block in purple, such as 9:00 PST to 12:00 PST, and compare it directly with the UTC row where it appears as 17:00 UTC to 20:00 UTC. You can drag the center of the selection to test another slot or use the left and right handles to resize it, which is practical when you are checking whether a Pacific morning meeting still lands inside a Europe-facing operations window.
Export and share the converted schedule: Once the range is selected, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially useful for sending a confirmed PST-to-UTC meeting block to distributed engineering teams, operations staff, or external partners so everyone receives the event in their own local calendar without manually re-converting the time.
Understanding the PST to UTC Time Difference
PST is Pacific Standard Time, UTC-8, while UTC is Coordinated Universal Time, UTC+0. That means UTC is 8 hours ahead of PST, so a time scheduled in PST appears later on the clock in UTC. For example, 9:00 PST = 17:00 UTC, 12:00 PST = 20:00 UTC, 15:00 PST = 23:00 UTC, and 18:00 PST = 2:00 UTC (next day).
This matters most when a workday in Pacific time stretches into late evening or crosses midnight in UTC. A late-afternoon PST task can become a next-day UTC event, which is important for release scheduling, compliance logs, server maintenance, and any workflow that uses UTC as the system record time.
PST is a standard-time abbreviation, and its daylight saving counterpart is PDT. UTC does not observe DST, so the difference changes during the part of the year when Pacific time switches away from PST and uses PDT instead. In practical terms, the 8-hour difference applies specifically when PST is in effect, and during DST months you need to use the Pacific daylight time setting rather than PST for accurate scheduling.
PST is used in parts of the United States, Canada, and Mexico, and the abbreviation is also used in the Philippines in some contexts, so it is important to confirm which PST reference a team is using before booking international meetings. In business systems, UTC is often the default for cloud infrastructure, developer logs, aviation data, and global platforms, which is why converting Pacific office hours into UTC is a common requirement.
Best Times for Calls and Meetings Between PST and UTC
The most practical overlap usually comes from the PST morning through early afternoon, because that maps into the UTC late afternoon through late evening. Using the standard examples, 9:00 PST = 17:00 UTC and 12:00 PST = 20:00 UTC, which creates a useful window for live meetings, project reviews, and same-day approvals between Pacific-based teams and organizations working on UTC schedules.
A 9:00 PST to 12:00 PST meeting block is often one of the cleanest options because it converts to 17:00 UTC to 20:00 UTC. That range is late enough for UTC-based teams to have completed most daytime work, while still being early enough for Pacific teams to stay inside normal office hours, making it suitable for SaaS operations, remote engineering standups, and customer onboarding calls.
If you push later into the Pacific afternoon, coordination becomes harder for UTC participants. For example, 15:00 PST = 23:00 UTC, which is already near the end of the day for many teams using UTC-based schedules, and 18:00 PST = 2:00 UTC (next day), which is generally impractical for live collaboration unless the meeting is tied to overnight operations, incident response, or 24/7 infrastructure support.
For recurring meetings, many teams choose a Pacific morning slot because it avoids crossing too far into the UTC night. This is especially relevant for companies running cloud services, cybersecurity monitoring, international media workflows, or logistics systems where UTC is the operational standard but decision-makers still work on Pacific business hours.
Frequently Asked Questions
What is the time difference between PST and UTC?
UTC is 8 hours ahead of PST. Since PST is UTC-8 and UTC is UTC+0, any time in PST converts forward by eight hours when shown in UTC, which is why 9:00 PST becomes 17:00 UTC.
When is 9 AM PST in UTC?
9:00 PST = 17:00 UTC. This is a common conversion for teams scheduling morning meetings on the U.S. and Canadian West Coast while coordinating with systems, dashboards, or colleagues who work in UTC.
When is 12 PM PST in UTC?
12:00 PST = 20:00 UTC. That makes Pacific noon a workable late-day UTC time for status calls, deployment approvals, and handoffs between West Coast business teams and globally distributed technical operations.
When is 3 PM PST in UTC?
15:00 PST = 23:00 UTC. This is still possible for some international coordination, but it is already quite late for teams working directly on UTC schedules, so it is usually better suited to urgent reviews or asynchronous follow-up.
When is 6 PM PST in UTC?
18:00 PST = 2:00 UTC (next day). This next-day rollover is important when you are planning maintenance windows, sending calendar invites, or documenting deadlines, because the UTC date changes even though the PST date has not yet ended.
Does the difference between PST and UTC change during DST?
Yes, the difference changes when Pacific time is no longer on PST and switches to PDT. UTC itself does not observe daylight saving time, so the shift happens only on the Pacific side; the 8-hour difference applies when PST is in effect, and during DST months you need to use PDT instead of PST.
What is the best meeting time between PST and UTC?
A strong option is the PST morning to midday window, because the examples show that 9:00 PST = 17:00 UTC and 12:00 PST = 20:00 UTC. That gives both sides a realistic business-hours overlap, which works well for remote team meetings, vendor calls, and international project check-ins.
Why do companies often convert PST to UTC?
Many global systems run on UTC even when employees work locally in PST. Engineering teams use UTC for server logs and deployments, operations teams use it for incident tracking, and international businesses rely on it to keep one consistent schedule across offices in North America, Europe, and Asia.
