Where UTC to Pacific conversions come up

UTC is the reference clock used by servers, cloud schedulers, log files and aviation, and Pacific Time is the zone where much of the software industry that depends on UTC is based. Reading one in terms of the other is a daily task for engineers on the West Coast.

The conversion is subtract eight hours in winter and seven hours in summer. 18:00 UTC is 10:00 AM PST in January and 11:00 AM PDT in July. Because the offset changes with daylight saving, a job scheduled in UTC lands at a different Los Angeles hour for part of the year.

Anyone who works with systems that report in UTC ends up converting to Pacific Time several times a week.

Cloud jobs and cron schedules

Cron expressions on cloud platforms such as GitHub Actions and AWS run in UTC, not local time.

  • A job at 08:00 UTC runs at 12:00 AM PST in winter, 1:00 AM PDT in summer
  • A nightly backup at 03:00 UTC starts at 7:00 PM PST the evening before
  • A deploy window of 17:00 UTC is 9:00 AM PST

The one-hour drift each March and November is a classic cause of "why did the job run an hour late" tickets.

Logs and incident timelines

Status pages and post-mortems are normally written in UTC, then read in local time by the people on call.

  • An alert at 22:30 UTC was 2:30 PM PST
  • An outage ending at 01:15 UTC ended at 5:15 PM PST the previous day
  • A customer ticket stamped 12:00 UTC arrived at 4:00 AM PST

Check the date as well as the hour: the UTC date is often a day ahead of the Pacific date after 4 PM.

Online events and releases

Global launches and live streams often publish a UTC time and leave readers to convert it.

  • 15:00 UTC is 7:00 AM PST or 8:00 AM PDT
  • 00:00 UTC is 4:00 PM PST the previous afternoon
  • 20:00 UTC is noon PST or 1:00 PM PDT

If you plan to attend, convert for the date of the event, not today’s date.

Deadlines quoted in UTC

Many hackathons, grant calls and contests state "23:59 UTC". For Los Angeles that is 3:59 PM PST in winter or 4:59 PM PDT in summer, so the deadline falls in the afternoon of the same day rather than at midnight.

Payment processors and API providers reset daily limits at 00:00 UTC. For a developer in California, the reset happens at 4:00 PM PST (5:00 PM PDT), which means "yesterday’s" quota resets before the end of the Pacific working day.

Seven or eight hours: the daylight saving effect

UTC never changes. California moves its clocks, so the gap is 8 hours from early November to mid March and 7 hours between those dates. The change is invisible in UTC timestamps, but visible in every Pacific wall clock.

Dates for 2026–27. Calculated from the IANA time zone database on Nov 6, 2026: today Los Angeles is 8 hours behind UTC. In northern winter the gap is 8 hours, in northern summer 7 hours. The clock changes ahead are:
  • Mar 14, 2027: Los Angeles moves to PDT (UTC−7); the gap becomes 7 hours
  • Nov 7, 2027: Los Angeles moves to PST (UTC−8); the gap becomes 8 hours

Be careful in the weeks around each change. A meeting stored as 17:00 UTC that sat at 9 AM in winter appears at 10 AM after the March clock change, unless the calendar is tied to a Los Angeles time instead.

Quick answers

What is 12:00 UTC in PST?

4:00 AM PST in winter and 5:00 AM PDT in summer.

Is PST UTC minus 7 or 8?

UTC minus 8. Pacific Daylight Time (PDT) is UTC minus 7, used from March to November.

What is 00:00 UTC in Los Angeles?

4:00 PM the previous day in winter, 5:00 PM the previous day in summer.

How do I convert UTC to PST quickly?

Subtract 8 hours in winter or 7 in summer. If the result goes below zero, add 24 and move back a day.

Why do servers use UTC instead of Pacific Time?

UTC does not change for daylight saving, so logs from different regions line up without conversion.
