UTC to Pacific Time (UTC to PT)

To convert UTC to Pacific Time (UTC to PT): in summer 5:00 PM UTC is 10:00 AM PDT, and in winter 5:00 PM UTC is 9:00 AM PST. The gap moves with US daylight saving, as explained below.

A wall-clock time in the source zone. 24-hour, so 3pm is 15:00.

This gap does NOT hold all year Convert through the offset in force on the date you care about.
The two ends switch on different dates, or one does not switch at all.
PDT is only in force part of the year United States: daylight time starts the second Sunday in March, at 02:00 local time and ends the first Sunday in November, at 02:00 local time (Energy Policy Act of 2005, in force since 2007). In 2026 that is 2026-03-08 to 2026-11-01. Los Angeles is on PST between those dates.

Military time zone letters Z (Zulu) is UTC. A to M run east of Greenwich an hour apart, N to Y west, and J is left out. A letter names an offset, so a zone that switches to daylight time changes letter: EST is R, EDT is Q.

How the Time Zone Converter works

UTC is UTC+00:00 and never shifts. PT means Pacific Time, whichever of its two offsets is in force: PST at UTC-08:00 in winter, and PDT at UTC-07:00 from the second Sunday in March to the first Sunday in November. So converting UTC to PT is two different subtractions depending on the date: PT is 7 hours behind UTC in summer and 8 hours behind it in winter.

The gap between these two is not the same all year, which is the thing to get right. PT shifts for daylight saving and UTC does not, so PT is 7 hours behind UTC from the second Sunday in March to the first Sunday in November, and 8 hours behind it for the rest of the year. In 2026 the switch dates are 2026-03-08 and 2026-11-01.

Worked through: in summer, 5:00 PM UTC is 10:00 AM PDT. In winter, 5:00 PM UTC is 9:00 AM PST.

Seven hours behind in summer and eight in winter, and the zone where a UTC day boundary falls in the middle of the working day. Midnight UTC is 5:00 PM in California from March to November and 4:00 PM the rest of the year, so a job scheduled at 00:00 UTC runs during business hours all year and moves an hour earlier in the local afternoon each November. A dashboard grouped by UTC day and read in Los Angeles splits every afternoon across two dates, and the split point shifts with the season.

UTC to PST has its own page, and it is a different question. That page converts the abbreviations exactly as written, which is right when an invitation names a specific offset. This one converts the zone (the clock on the wall in Los Angeles), which is almost always what someone typing UTC to PT wants. The converter above is preset to the summer pairing, UTC to PDT, because that is in force for about eight months of the year; for a date between November and March, pick UTC and PST in the lists instead.

Common times for this pair, summer and winter:

- 12:00 AM UTC is 5:00 PM PDT the previous day; in winter, 12:00 AM UTC is 4:00 PM PST the previous day - 5:00 PM UTC is 10:00 AM PDT; in winter, 5:00 PM UTC is 9:00 AM PST - 7:00 PM UTC is 12:00 PM PDT; in winter, 7:00 PM UTC is 11:00 AM PST - 11:00 PM UTC is 4:00 PM PDT; in winter, 11:00 PM UTC is 3:00 PM PST

Time Zone Converter FAQ

What is the time difference between UTC and PT?

It depends on the date. PT is 7 hours behind UTC from the second Sunday in March to the first Sunday in November, while UTC to PDT applies, and 8 hours behind it for the rest of the year, under UTC to PST.

What time is 5:00 PM UTC in PT?

In summer, 5:00 PM UTC is 10:00 AM PDT. In winter, 5:00 PM UTC is 9:00 AM PST. The hour of difference between those two answers is daylight saving, applied at one end only.

Is PT the same as PST?

Only in winter. PT is Pacific Time, whichever offset is in force: PST at UTC-08:00 from the first Sunday in November until the second Sunday in March, and PDT at UTC-07:00 the rest of the time. PST written in July is, strictly, an hour away from the clock in Los Angeles. That is why PT is the safer thing to write in an invitation that has to be right all year.

When does the difference between UTC and PT change?

At the United States daylight saving switch, which starts on the second Sunday in March, at 02:00 local time and ends on the first Sunday in November, at 02:00 local time (Energy Policy Act of 2005, in force since 2007). In 2026 that is 2026-03-08 to 2026-11-01. Between those dates the gap is 7 hours; outside them, 8 hours.

Is there anything specific to this pair worth knowing?

Seven hours behind in summer and eight in winter, and the zone where a UTC day boundary falls in the middle of the working day. Midnight UTC is 5:00 PM in California from March to November and 4:00 PM the rest of the year, so a job scheduled at 00:00 UTC runs during business hours all year and moves an hour earlier in the local afternoon each November. A dashboard grouped by UTC day and read in Los Angeles splits every afternoon across two dates, and the split point shifts with the season.
