Convert PST to GMT
Enter a date and time in Pacific Standard Time (UTC-8) to instantly convert it to Greenwich Mean Time (UTC+0).
Tip: PST is always 8 hours behind GMT. This tool uses a fixed PST offset and does not auto-switch for daylight saving time.
How this PST to GMT calculator works
Time zone conversion sounds tricky, but for PST to GMT it is straightforward: add 8 hours. Pacific Standard Time (PST) is UTC-8, while GMT is UTC+0. Because GMT is ahead, converting from PST to GMT moves the clock forward.
Example: if it is 2:30 PM in PST, add 8 hours and you get 10:30 PM in GMT on the same day. If the result crosses midnight, the GMT date will roll into the next calendar day.

Why people use PST to GMT conversion
GMT is often used as a neutral reference point when teams are spread across regions. If you work with clients in Europe, run global webinars, or coordinate support shifts, converting PST to GMT helps prevent missed meetings and scheduling confusion.
- Remote work: Align standups and deadlines across continents.
- Trading and finance: Track market announcements by universal time references.
- Travel planning: Compare departure and arrival schedules accurately.
- Technical operations: Match server logs and deployment windows with standardized timestamps.
PST vs PDT: important distinction
One common mistake is mixing up PST and PDT. PST is standard time (UTC-8). PDT is daylight time (UTC-7). This calculator is specifically for PST to GMT conversion.
If your local region is observing daylight saving time, your clock may actually be on PDT. In that case, use a PDT converter instead or manually add 7 hours to reach GMT.
Best practices for scheduling across time zones
- Always include the time zone in invites (e.g., “9:00 AM PST”).
- Add a second reference time for international attendees (e.g., GMT).
- Double-check date rollovers for late-afternoon and evening PST meetings.
- Use 24-hour format for technical teams to avoid AM/PM confusion.
