How Does Daylight Saving Time Affect PDT Time?

How does daylight saving time affect PDT time? PDT is actually the result of DST — it's what Pacific Time becomes when clocks spring forward. Here's the full explanation.

How Does Daylight Saving Time Affect PDT Time?

PDT (Pacific Daylight Time) is DST. PDT is what Pacific Time becomes when Daylight Saving Time is in effect. Without DST, there would be no PDT — only PST year-round.

PST vs PDT

Abbreviation	UTC Offset	When Active	DST?

How DST Creates PDT

In winter, Pacific Time = PST (UTC-8)

On the second Sunday of March, clocks spring forward 1 hour

Pacific Time is now UTC-7 = PDT

On the first Sunday of November, clocks fall back

Pacific Time returns to PST (UTC-8)

2026 Switch Dates

States That Stay on PST Year-Round

No US state stays on PST year-round. Arizona uses MST year-round (skipping MDT), but no state skips PDT while staying on Pacific Time.

Quick Answer

PDT is Pacific Time during DST (UTC-7). Without DST, PDT wouldn't exist — it's the daylight version of PST. PDT runs from March 8 to November 1, 2026.
