GMT to PST Converter Overview
In today’s interconnected world, managing schedules across time zones is more important than ever. One common conversion involves Greenwich Mean Time (GMT) and Pacific Standard Time (PST). Whether you’re scheduling international meetings, planning travel, or attending online events, knowing the precise GMT to PST conversion is crucial. This guide covers everything you need to understand and use a GMT to PST converter efficiently.
Understanding GMT and PST Time Zones
What is GMT (Greenwich Mean Time)?
Greenwich Mean Time (GMT) is the time standard that forms the basis for all other time zones around the world. It is centered at the Prime Meridian (0° longitude) in Greenwich, London, and serves as a global reference.
- GMT = UTC +0 hours
- Considered a universal time reference
- Does not change with daylight saving time
What is PST (Pacific Standard Time)?
Pacific Standard Time (PST) is used in the western regions of the United States and Canada, including California, Washington, and British Columbia. PST is eight hours behind Coordinated Universal Time (UTC-8). During daylight saving months, PST shifts to Pacific Daylight Time (PDT, UTC-7).
- PST = UTC -8 hours
- Observed in western USA and parts of Canada
- Shifts to PDT during daylight saving time
GMT to PST Time Difference
The difference between GMT and PST is crucial for planning and scheduling:
- Standard Difference: GMT is 8 hours ahead of PST.
- During Daylight Saving: GMT to PDT difference reduces to 7 hours.
For example: 12:00 PM GMT corresponds to 4:00 AM PST. During daylight saving, 12:00 PM GMT equals 5:00 AM PDT. Understanding this difference ensures smooth scheduling across continents.

How It Works
Select GMT as the Source Time Zone:
Begin by selecting Greenwich Mean Time (GMT) as your source time zone. This ensures that the input time is accurately recognized relative to the universal time standard, providing a precise starting point for conversion.
Choose PST as the Target Time Zone:
Next, select Pacific Standard Time (PST) as the target time zone. This selection allows the converter to apply the correct UTC offset and account for any time differences, ensuring your converted time is accurate and ready to use for planning purposes.
Enter GMT Time:
Input the exact time in GMT that you want to convert. For example, you can enter "6:00 PM GMT". You may also enter times using 24-hour notation like "18:00 GMT" if that is your preference. Precision here is key for accurate conversion results.
Get PST Time Instantly:
Once you input the GMT time, the converter immediately subtracts 8 hours and displays the corresponding Pacific Standard Time. For instance, "6:00 PM GMT" will instantly convert to "10:00 AM PST", giving you an accurate and reliable result without manual calculations.
Apply in Scheduling:
Use the converted PST time to efficiently plan and schedule calls, meetings, flight itineraries, software tasks, or collaborative activities. This tool helps prevent miscommunication across time zones, allowing you to coordinate events seamlessly between GMT and PST regions. Whether for personal, professional, or academic purposes, this step-by-step conversion process ensures accuracy and convenience.
