For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about PST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Is PST the same as PDT?
- Not exactly. PST (UTC-08:00) is the standard offset used in winter, while PDT (UTC-07:00) is the daylight saving offset used from the second Sunday in March to the first Sunday in November.
- Which countries use Pacific Standard Time?
- The United States (Los Angeles and the West Coast) and Mexico (Tijuana, in Baja California). British Columbia in Canada last used PST in early 2026 but stays on UTC-07:00 all year from November 1, 2026.
- When do clocks change in this region?
- Clocks spring forward to PDT at 2:00 a.m. on the second Sunday in March and fall back to PST at 2:00 a.m. on the first Sunday in November. British Columbia is the exception: it moved to permanent UTC-07:00 in 2026 and no longer changes its clocks.
- Why do I sometimes see UTC-8 and other times UTC-7?
- UTC-08:00 is the standard winter offset (PST), while UTC-07:00 is the summer daylight saving offset (PDT). Check which period you're in to know which applies.
- Are U.S. Pacific Time rules the same as in Vancouver/Tijuana?
- Los Angeles and Tijuana follow the same rules and switch on the same dates. Vancouver no longer does: from November 1, 2026 British Columbia stays on UTC-07:00 all year, one hour ahead of Los Angeles in winter.
- Is this the same as Mountain Time?
- No, Mountain Time is one hour ahead of Pacific Time (typically UTC-07:00 / UTC-06:00). Pacific is the westernmost mainland U.S. time zone in this region.
- When is it easiest to schedule calls across this region?
- Mid-morning usually works well. Los Angeles and Seattle always share the same time; Vancouver matches them from March to November and is one hour ahead in winter, so 10:00 a.m. in Los Angeles is 11:00 a.m. in Vancouver then.
- When do clocks spring forward again after falling back in November?
- On the second Sunday in March, when clocks return to PDT (UTC-07:00).
