GMT to PST Conversion Information

Time Zone Basics

Greenwich Mean Time (GMT) is the time at the Royal Observatory in Greenwich, London, and serves as the reference point for world time zones. Pacific Time in the United States alternates between PST (Pacific Standard Time) and PDT (Pacific Daylight Time) depending on the season.

Time Differences

Standard Time (PST): GMT is 8 hours ahead of PST. When it's 12:00 PM (noon) GMT, it's 4:00 AM PST.

Daylight Time (PDT): GMT is 7 hours ahead of PDT. When it's 12:00 PM (noon) GMT, it's 5:00 AM PDT.

Important Notes

• GMT never changes - it remains constant year-round as the global time reference

• Pacific Time switches between PST (winter) and PDT (summer) due to daylight saving

• California, Washington, Oregon, Nevada, and parts of Idaho observe Pacific Time

• Daylight saving time runs from the second Sunday in March to the first Sunday in November

• This time difference affects international business hours and global scheduling

Turn GMT Into Pacific Time

If your work or life spans across continents, converting time from GMT to Pacific Time can get messy—especially when daylight saving changes the offset. This tool makes it simple. Whether you’re planning a webinar from London or setting a deadline for your San Francisco office, just drop in the GMT time and get the correct Pacific time, right on the spot.

What this converter handles for you

You provide a time and date in GMT. The calculator checks whether Pacific Time is on daylight saving for that moment. Then, it subtracts either 8 or 7 hours and gives you the exact corresponding time in PST or PDT. It also updates the zone name clearly so you know whether it’s standard or daylight time.

Why this is a better way to convert

The time difference between GMT and Pacific Time changes depending on the season. If you're relying on fixed offsets, you might miss that the US flips its clocks before Europe does—or that GMT never changes. This tool figures all of that out behind the scenes, giving you a clean answer every time.

Using it is as simple as it looks

1. Enter your GMT date and time

Use the input section on the left labeled “GMT Time.” As soon as both fields are filled, you can hit the convert button.

2. Tap the convert button

Click the 🌎 Convert GMT to PST button. The Pacific time appears immediately on the right, along with the date and day of the week.

3. Choose your time display

If you want to switch between 12-hour and 24-hour format, click the “12 Hour” toggle. Everything updates automatically, including the live clocks.

Helpful extras baked right in

Live clocks for both zones

At the bottom of the tool, you’ll find a live-updating display of current time in GMT and Pacific Time. These are useful if you're checking the time difference before a real-time event.

Daylight saving status displayed clearly

Below the clocks, there’s a text line that shows whether Pacific Time is currently in daylight or standard time. It updates live and adjusts the label on the Pacific zone too.

Output includes full date and weekday

In addition to the time, the result also shows the converted date and the day name. That’s helpful if you're working across the dateline and want to avoid date mixups.

Here’s a real-world case where it helps

Say you're in Accra, Ghana (GMT), preparing a Zoom call with a team in Portland, Oregon. You want to set the meeting for 16:00 GMT on September 2. Enter that into the calculator, and it gives you 9:00 AM PDT. That’s the right local time for your colleagues during US daylight saving, and now your invite will hit everyone at the right hour.

Take the confusion out of GMT to Pacific conversions

With different daylight saving rules and year-round offsets, getting this time conversion wrong is easy. This tool makes it easy to get right. Just enter your GMT values, click once, and get a Pacific time you can count ony.
