PST to UTC Converter (Pacific Time to Coordinated Universal Time)

Mid-January 2026: UTC is 8 hours ahead of PST. Mid-July 2026: UTC is 7 hours ahead of PDT.

Pacific Time is UTC-08:00 in winter (PST) and UTC-07:00 in summer (PDT). To change a Pacific time to UTC, add 8 hours in winter or 7 hours in summer. A 4:00 p.m. PST deadline is midnight UTC at the end of the day, which falls on the next UTC date.

The usual users are developers and operations teams on the West Coast. Cloud consoles, logs and deployment schedules are usually expressed in UTC, while the people running them sit in San Francisco, Seattle or Los Angeles.

How to use this tool

1. Pick a date and time in PST. The date matters when daylight saving time is in force.
2. Read the matching time in UTC, with both UTC offsets.
3. Use "Use current time" for now, or the tables below for a quick look.

Formula

UTC time = PST time − (PST UTC offset) + (UTC UTC offset)

The converter looks up both UTC offsets for the actual instant in the saved IANA time zone rules, so daylight saving changes are included automatically.

Example

Worked with the saved rules:

9:00 AM PST on March 2, 2026 = 5:00 PM UTC

6:30 PM PDT on August 3, 2026 = 1:30 AM UTC (next day)

Time difference through the year

The difference depends on the date when either place moves its clocks. These are the offsets on two reference days, from the saved IANA rules:

Clock changes in 2026

Between these dates the difference shifts by the size of the change.

Release windows and cut-offs

When a company freezes changes at 5:00 p.m. Pacific, UTC-based tools register the freeze at 01:00 UTC the next day in winter and 00:00 UTC in summer. A report that is generated by date in UTC can therefore group Pacific evening work under the following day.

Pacific morning is just as awkward in the other direction: 6:00 a.m. PST is 14:00 UTC, so a 06:00 start in Seattle is in the afternoon for a colleague in Europe.

The date line for a West Coast evening

After 4:00 p.m. PST, the UTC date is already the next one, and after 5:00 p.m. PDT in summer. Anything stamped in UTC and viewed on a Pacific calendar needs this correction, or entries seem to jump forward a day.

The shift happens on March 8 and November 1 in 2026. Because the Pacific clock moves and UTC does not, a job set to a fixed Pacific time changes its UTC time by an hour on those dates.
