Typical Pacific-to-UTC conversions

Converting Pacific Time to UTC means adding eight hours in winter and seven in summer. A 9:00 AM PST meeting is at 17:00 UTC, and 9:00 AM PDT is 16:00 UTC. The figure is what colleagues in other countries need in order to place a West Coast event on their own clocks.

California-based teams spend a lot of time on this conversion. Release windows, support rotas, ad campaigns and on-call handovers are all agreed in Pacific time and then pushed into systems that run on UTC.

The gap is large enough that the UTC date often differs from the Los Angeles date.

Product launches and keynotes

West Coast companies announce events in Pacific Time and expect the rest of the world to calculate the local time.

  • 10:00 AM PST is 18:00 UTC; 10:00 AM PDT is 17:00 UTC
  • A keynote at 1:00 PM PT is 20:00 or 21:00 UTC
  • A press embargo lifting at 6:00 AM PT is 13:00 or 14:00 UTC

For an event in March or November, check whether the US has already changed its clocks.

On-call and support rotas

Follow-the-sun support teams hand over at fixed UTC times, and the West Coast slots move twice a year.

  • The 17:00 UTC handover is 9:00 AM PST
  • A 00:00 UTC shift start is 4:00 PM PST the previous day
  • A shift ending at 08:00 UTC ends at 12:00 AM PST

A rota agreed in UTC never drifts for the engineers outside the US.

Scheduling campaigns

Marketing teams in California often schedule posts and emails in Pacific time and the platform stores them in UTC.

  • An email set for 8:00 AM PST goes out at 16:00 UTC
  • A social post at noon PST is 20:00 UTC
  • A sale ending at 11:59 PM PST ends at 07:59 UTC the next day

A "midnight Pacific" sale ends at 08:00 UTC, so overseas customers may see it end in the morning.

Deadlines at the end of the Pacific day

The Pacific end of day is late in UTC terms. A deadline of 11:59 PM PST is 07:59 UTC on the following day. Hackathons, grant calls and app-store release dates that use Pacific time therefore give people in Europe and Asia extra hours.

For a contract that says "by close of business Pacific", assume 5 PM, which is 01:00 UTC the next day in winter and 00:00 UTC in summer.

Eight hours becomes seven

California changes its clocks on the second Sunday of March and the first Sunday of November, while UTC stays fixed. The result is a gap of 8 hours in winter and 7 hours in summer.

Dates for 2026–27. Calculated from the IANA time zone database on Nov 6, 2026: today UTC is 8 hours ahead of Los Angeles. 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

A recurring event pinned to a Pacific time shifts by one hour in UTC when the clocks change, which is why release calendars for global products are normally written in UTC first and in local times second.
