Last updated Apr 26, 2026. Representative zones, offset ranges, and city usage are refreshed from the current timezone dataset so abbreviation pages stay tied to real zones instead of static boilerplate.
PDT is a North or South American civil-time label, currently 7h behind UTC at -07:00. The label covers 3 IANA zones across 3 countries, with Los Angeles as the busiest live reference.
The busiest cities using PDT in the current catalog are Los Angeles, Tijuana, San Diego, Mexicali, and San Jose. The lead live reference on this page is Los Angeles (America/Los_Angeles), currently at -07:00 (PDT). Those cities are what give PDT its actual feel rather than the abstract offset.
PDT currently shows -07:00, but America/Los_Angeles observes seasonal clock changes — the next transition is around November 1, 2026. That means the offset on this page is a snapshot, not a permanent fact, so long-range scheduling should pin the underlying IANA zone instead of the abbreviation.

America/Los_Angeles has an upcoming offset change on November 1, 2026. After that point, PDT on this page will read a different UTC offset until the next transition, so any saved timestamp should anchor to the IANA zone rather than the abbreviation.
For precise work, the safest equivalent of PDT is the exact IANA zone used by your city or system. America/Los_Angeles sits at -07:00, behind UTC, which means daily logs in this zone reach a new calendar date after UTC does — relevant for date-aligned reports and billing cutoffs.
Even with one canonical meaning, PDT spans 3 IANA zones — pin to America/Los_Angeles when DST or historical-rule precision matters.
