PST to GMT Conversion Guide

What is PST to GMT Conversion?

PST to GMT conversion helps you translate time between Pacific Standard Time and Greenwich Mean Time zones. PST is UTC-8 and becomes PDT (UTC-7) during daylight saving time. GMT is UTC+0 and remains constant year-round as it is equivalent to Coordinated Universal Time (UTC).

Time Zone Information

Pacific Standard Time (PST): Used in western US including Los Angeles, San Francisco, Seattle, and Portland. UTC-8 in winter, becomes PDT (UTC-7) during daylight saving.

Greenwich Mean Time (GMT): Used in UK (winter), Ireland, Portugal, and Iceland. Always UTC+0 and equivalent to Coordinated Universal Time (UTC).

Time Difference: GMT is 8 hours ahead of PST, or 7 hours ahead of PDT during daylight saving time.

Daylight Saving Time Impact

Winter Period (PST): November to March - GMT is 8 hours ahead of PST

Summer Period (PDT): March to November - GMT is 7 hours ahead of PDT

GMT Time: No daylight saving time changes - always UTC+0 year-round

Conversion Tips & Best Practices

• Business meetings work best when PST is 9-11 AM for GMT afternoon hours (5-7 PM)

• Remember that dates often change across the conversion - GMT is often a day ahead

• Use 24-hour format to avoid AM/PM confusion when scheduling internationally

• PST transitions to PDT on the second Sunday in March at 2:00 AM

Built for people who need accurate cross-timezone planning

This tool is ideal if you’re working across time zones, especially between tech hubs like San Francisco and London. Instead of relying on guesswork or searching for "current time in GMT," you get a clear, fast answer based on the exact date and time you select. You can flip the direction, convert now, or compare different dates throughout the year, all without touching a spreadsheet.

How to convert times like a pro

Step 1: Choose your time

Pick a date and a time using the calendar and clock inputs. The tool starts with Pacific Time, but you can switch to GMT as your starting point from the dropdown menu.

Step 2: Let it convert or press the button

By default, the conversion happens automatically as you adjust your inputs. If you want manual control, you can turn that off and use the “Convert Time” button instead.

Step 3: Read everything clearly

You’ll get the converted time, a full date label, and extras like the time difference, DST status, and each zone’s UTC offset. It's all laid out right under your inputs so you don’t have to scroll or squint.

Useful extras you won’t find in a basic search

Swap Timezones: See what a time in GMT becomes in Pacific Time with one click.
Live Clock Display: The current time updates every second for both zones. Great if you’re trying to catch someone before their office closes.
Time Format Toggle: Use 12-hour or 24-hour display depending on what’s more intuitive for you.
Daylight Saving Awareness: This matters more than people think. GMT never changes, but Pacific Time does. This converter automatically adjusts for it.
Offset Display: Show each zone’s UTC offset if you’re coordinating with people who think in universal time.

One tool that works for every scenario

Imagine you’re planning an online training from Vancouver for attendees in Portugal. You want it to start at 9:00 AM their time. Just open the converter, flip to GMT as your input, and you’ll know to be online by 1:00 AM Pacific Time. Whether it’s early meetings, late-night events, or pre-recorded content timing, this tool keeps you in control.

Practical scheduling made easier

The biggest challenge in cross-timezone communication is often the uncertainty. You don’t want to be an hour early or late just because you forgot about daylight saving. This converter handles that logic in the background and gives you clean, accurate results. From West Coast project calls to coordinating with teams in West Africa, this page keeps things running on time.
