About PDT
PDT is the daylight saving time of the US West Coast.
Working with PDT
Clocks in this zone change twice a year: UTC-08:00 outside daylight saving and UTC-07:00 during it. Because PDT names only one of those two states, a time labelled PDT is ambiguous until you also know the date it refers to.
When it is noon UTC, Pacific Daylight Time reads 05:00; midnight UTC is 17:00 here. PDT runs 7 h behind UTC, so its calendar day begins after the reference clock’s does.
The same standard offset, UTC-07:00, is kept by MST, though each follows its own daylight saving rules — or none — so they do not stay aligned all year. One hour to the west of PDT in this directory sits PST (UTC-08:00); one hour to the east, CST (UTC-06:00).
Clock changes in PDT
PDT follows the North American rule: clocks go forward on the second Sunday in March and back on the first Sunday in November, at 02:00 local time.
| Date | Change | New offset |
|---|---|---|
| November 1, 2026 | Clocks go back one hour on Nov 1, 2026 at 01:00, moving from UTC-07:00 to UTC-08:00. | UTC-08:00 |
| March 14, 2027 | Clocks go forward one hour on Mar 14, 2027 at 03:30, moving from UTC-08:00 to UTC-07:00. | UTC-07:00 |
Of the reference zones in the table below, New York, London, Berlin and Sydney observe daylight saving, so their difference from PDT shifts twice a year; UTC, Dubai, Kolkata, Singapore and Tokyo stay fixed.
Where PDT is used
In this directory 4 cities keep PDT: Los Angeles, San Francisco, Seattle and Las Vegas. Between them they cover United States.
Where PDT stands today
PDT is currently UTC-07:00. The next change is on November 1, 2026, 23 days from the day this page was generated, when clocks move to UTC-08:00. Until then any time expressed as PDT carries the offset shown above; after it, the same wall-clock reading corresponds to a different instant. This is the reason a difference against another zone is only reliable when you attach a date to it.
Summer time is in force now, so the offset shown is the seasonal one rather than this region's standard time.
A working day on PDT
Taking Los Angeles as the reference point for PDT, and a working day as 09:00 to 17:00:
- New York’s working day overlaps with Los Angeles’s for 5 hours, from 09:00 to 14:00 Los Angeles time.
- London has no overlap at all: when it is 09:00 there, it is already 01:00 in Los Angeles, so a call means an early start or a late finish for someone.
- Tokyo has no overlap at all: when it is 09:00 there, it is already 17:00 in Los Angeles, so a call means an early start or a late finish for someone.
On the June solstice the sun rises in Los Angeles at about 05:42 and sets at about 20:07; on the December solstice it rises at about 06:54 and sets at about 16:47.
How PDT compares with other zones
Right now PDT runs behind every reference zone in the table: UTC, New York, London, Berlin, Dubai, Kolkata, Singapore, Tokyo and Sydney.

| New York | UTC-04:00 | 3h behind |
| London | UTC+01:00 | 8h behind |
| Berlin | UTC+02:00 | 9h behind |
| Dubai | UTC+04:00 | 11h behind |

Frequently asked questions
What is PDT?
Pacific Daylight Time, PDT, is UTC-07:00. PDT is the daylight saving time of the US West Coast.
What is the IANA identifier for PDT?
America/Los_Angeles — the entry that covers Los Angeles in the tz database. Use it rather than PDT in software: PDT names one season, America/Los_Angeles names the rules for every date.
Does PDT change for daylight saving?
Yes — Pacific Daylight Time changes its clocks (standard UTC-08:00, summer UTC-07:00), as do New York, London, Berlin and Sydney among the zones compared on this page.
How do I convert PDT to my local time?
One hour to the west of PDT in this directory sits PST (UTC-08:00); one hour to the east, CST (UTC-06:00). For anything beyond that, the converter applies the rules of America/Los_Angeles for the date you give it rather than a remembered figure.
Which cities use PDT?
In this directory 4 cities keep PDT: Los Angeles, San Francisco, Seattle and Las Vegas. Between them they cover United States. The boundary is legal rather than geographic: it follows the borders of United States, not a line of longitude.
What should I put in a configuration file for PDT?
America/Los_Angeles, never PDT. That entry carries the rules Los Angeles actually follows, including when daylight saving starts and ends, so software using it stays correct through a change that a stored offset would miss.
