How the gap moves through the year

Phoenix is 1 hour ahead of Los Angeles for about 4 months of the year.

From the second Sunday in March (when Los Angeles moves forward), Phoenix and Los Angeles show the same clock time.

From the first Sunday in November (when Los Angeles falls back), Phoenix is 1 hour ahead of Los Angeles.

Los Angeles moves its clocks forward one hour on the second Sunday in March at 2:00 am local time and back on the first Sunday in November at 2:00 am, switching between Pacific Standard Time (UTC−8) and Pacific Daylight Time (UTC−7).

Phoenix does not change its clocks: it stays on UTC−7 (Mountain Standard Time) all year.

Next clock change for this pair, as of when this page was built (2026-10-20): Los Angeles falls back on Sun 1 November 2026.

Everything on this page also holds if you swap Los Angeles for Tijuana, San Diego, San Francisco, Seattle or Las Vegas — those cities follow exactly the same clock all year.

Common mistakes with Los Angeles and Phoenix

  • Forgetting that the gap changes even though Phoenix never touches its clocks: Los Angeles does, so a meeting fixed in Phoenix time moves by an hour for people in Los Angeles.
  • Writing “PST” all year for Los Angeles. In summer the zone is Pacific Daylight Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
