How to Convert GMT to PST

Pick the date and time in Greenwich Mean Time (UTC +0) that you want to convert. Hit "Now" to load the current GMT time instantly, or use "+1h" to step forward and compare.
The equivalent Pacific Standard Time (UTC -8) time appears immediately. Since PST is 8 hours behind of GMT, most daytime conversions stay on the same calendar day.

Why Choose Our GMT to PST Converter
When someone in Universal suggests 5:00 PM GMT, that's 9:00 AM PST. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night GMT times can land on a different date in PST because of the 8 hours offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.
Daylight Saving adjustments can widen or narrow the GMT–PST gap by an hour. During transition weeks many people get it wrong. This converter pulls the current UTC offsets automatically, so the result is right even on the changeover day.
Product launches, sports matches, and webinars are often announced in GMT. Convert the event time to PST so you know exactly when to tune in — with a 8 hours difference, a morning event in Universal hits the evening in United States.
