PT to GMT Conversion Guide

What is PT to GMT Conversion?

PT to GMT conversion helps you translate time between Pacific Time and Greenwich Mean Time. Pacific Time switches between PST (UTC-8) in winter and PDT (UTC-7) in summer. GMT is technically UTC+0 year-round, though the UK observes BST (UTC+1) during summer months. The time difference varies between 7-9 hours depending on daylight saving periods.

Time Zone Information

Pacific Time (PT): Used in western United States and Canada. Switches between PST (UTC-8) in winter and PDT (UTC-7) in summer following North American daylight saving rules.

Greenwich Mean Time (GMT): The mean solar time at the Royal Observatory in Greenwich. Technically UTC+0, though UK observes BST (UTC+1) during summer.

Time Difference: 8 hours (PST to GMT), 7 hours (PDT to GMT), 9 hours (PST to BST), 8 hours (PDT to BST).

Daylight Saving Time Impact

Pacific DST: Observed from second Sunday in March to first Sunday in November, switching from PST to PDT (UTC-7)

UK BST: British Summer Time (UTC+1) observed from last Sunday in March to last Sunday in October

Variable Differences: Time difference changes throughout the year due to different DST start/end dates between regions

Common Conversion Examples

• Time difference ranges from 7-9 hours depending on which regions are observing DST

• Best meeting times: PDT 9:00-11:00 AM corresponds to BST 5:00-7:00 PM

How this tool helps you stay on top of time zones

The Pacific Time to GMT Converter lets you easily figure out what time it is across the Atlantic. It takes into account daylight saving time in both the US and UK, so you don’t have to second-guess your math or Google it for the tenth time. Whether you're scheduling a morning stand-up or a late-night webinar, it gives you the exact converted time you need, right when you need it.

What it actually does behind the scenes

This calculator takes a date and time you enter in either Pacific Time or GMT, figures out the current daylight saving status for that day in both regions, and then gives you the matching converted time on the other side. You can switch directions, set current time instantly, and even control the display format. It updates instantly when auto mode is on and shows you time offsets, DST info, and live clocks.

Using the converter step by step

1. Choose your direction

Pick which time zone you're entering the time from. By default, it's set to Pacific Time. If you're converting the other way, use the "Swap" button to flip the inputs.

2. Enter your date and time

Use the calendar and time picker to select your local time. Once entered, the converter will instantly give you the equivalent time in the other zone—unless you've turned off auto convert, in which case just tap "Convert Time."

3. Adjust optional settings

Auto Convert: When checked, any change to input updates the result immediately.
Daylight Saving Aware: Keeps the math correct across seasons and countries.
Show UTC Offset: Adds or removes the +0 or -8 style indicators next to each time zone.
Show Seconds: Controls whether seconds show up in the live clocks and results.

4. Check the live clocks

You’ll also see real-time PT and GMT clocks ticking away at the bottom, helpful when you're planning something “right now” or want to cross-check your result.

Answers to things you’re probably wondering

What happens during daylight saving switches?

The converter accounts for both US and UK daylight saving calendars automatically if DST awareness is turned on. This means it’ll adjust time difference from 8 hours (standard time) to 7 or 9 hours, depending on which side is in daylight saving at that moment.

What if I need to convert UK time to PT?

Use the “Swap” button. It flips the input/output so you can go in either direction. You'll still see all the same details like offsets and DST status, just reversed.

Is it good for planning international calls?

Yes, especially if you’re working with teams across the US WEST Coast and the UK or West Africa. You can pinpoint overlaps in business hours easily without fussing over whether it’s BST or GMT, PDT or PST.

Here’s a real-world example

If you're in San Francisco planning a 9:00 AM meeting on a Tuesday in March, and you're inviting someone in Liverpool, plug in your local time. The converter will show you that 9:00 AM PDT becomes 5:00 PM in the UK during British Summer Time. No calculators. No charts. Just clean, clear info.

Let this tool take the guesswork out of global scheduling

Time zones don’t have to be a headache. With this converter, you can stop second-guessing and get on with your day, knowing your meetings, events, and deadlines are lined up just right on both sides of the ocean.
