PDT
Pacific Daylight Time
Pacific Daylight Time (PDT) governs the West Coast rhythms of the U.S., Canada, and Mexico’s Baja Peninsula, aligning major tech, entertainment, and maritime hubs during the longer daylight months. It shifts the region’s clocks forward seven hours behind UTC each spring to maximize evening light, then reverts with the fall reset.

IANA zones · the technical identifiers
The 3 zones that resolve to PDT.
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 PDT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- What does PDT cover outside the U.S.?
- Besides the U.S. West Coast, PDT also includes Canada’s Lower Mainland (like Vancouver) and Mexico’s Baja California zone (including Tijuana), creating a unified three‑country corridor during the summer months.
- When do clocks change in PDT?
- In the PDT region, clocks typically spring forward in early March and fall back in early November, giving about eight months of daylight saving time.
- Why does this region observe DST?
- The shift aims to extend usable daylight into the evening, supporting tourism, outdoor activities, and energy savings along the Pacific Coast and border regions.
- When is the next time change?
- The next scheduled transition is on 2026‑11‑01 at 1:00 a.m. local PDT, after which the region will move back to standard time (PST).
- How does this region’s DST design influence global teams?
- West‑coast companies and cross‑border partners often plan around the long summer window of matching UTC-7 offsets with other summer‑adjusting regions, simplifying coordination with Europe and eastern North America.
