UTC to PST
UTC deploy and overnight stamps to Pacific: subtract 8 hours for PST or 7 for PDT. Early UTC mornings often fall on the previous Pacific date.
04:00 UTC Tuesday is 8:00 PM PST Monday in Los Angeles. Use GMT to PST for GMT-worded notices; use this page for CI/CD and cloud consoles.

About UTC and Pacific Time
Coordinated Universal Time (UTC) stays on a fixed offset with no daylight saving shift. Pacific Time (PT) covers places such as Los Angeles, San Francisco, Vancouver; it uses PST in winter and PDT in summer.
Pacific Time is 8 hours behind UTC during PST and 7 hours behind UTC during PDT; confirm the selected date above for the exact gap. During daylight saving time, Pacific Time regions that observe DST switch from PST to PDT. Use the live clocks, slider, and grid above to confirm the exact local times for your date.

UTC deploys and the Pacific calendar date
This conversion is built for global release windows and overnight UTC stamps that need a Los Angeles, San Francisco, Seattle, or Vancouver civil time. Coordinated Universal Time is fixed. Pacific Time (PT) uses Pacific Standard Time (PST, UTC−8) in winter and Pacific Daylight Time (PDT, UTC−7) in summer. Pacific is 8 hours behind UTC during PST and 7 hours behind during PDT. Confirm the selected date above for the exact gap.
Subtract eight hours for PST, or seven for PDT. 12:00 UTC is 4:00 AM PST or 5:00 AM PDT—often still the previous evening on the West Coast when the UTC hour is early.
Why the date row matters more here than on Eastern
The Pacific gap is larger, so early UTC mornings routinely land on the previous Pacific calendar day. Check both columns on this page:
- 04:00 UTC Tuesday = 8:00 PM PST Monday (Los Angeles)
- 05:00 UTC Tuesday = 9:00 PM PST Monday / 10:00 PM PDT Monday
- 17:00 UTC = 9:00 AM PST or 10:00 AM PDT same calendar morning
- 20:00 UTC = 12:00 PM noon PST (December, Seattle)
A “Tuesday 04:00 UTC” deploy note is Monday evening for California on-call staff.
Maintenance windows quoted in UTC
Global change tickets often say “06:00 UTC.” That is 10:00 PM PST the prior evening (or 11:00 PM PDT). West Coast responders should convert with the date picker before assuming same-day local time. Arizona is not Pacific—Phoenix stays on MST year-round; see the Arizona DST guide.
If your timestamp says GMT or Zulu instead of UTC
All three labels are UTC+0 here, so this page is the right one whether the stamp reads 12:00 UTC, 12:00 GMT, or 1200Z. The one label that is not UTC+0 is BST: a London wall clock in July is UTC+1, an hour ahead of everything on this page. Which label belongs where is covered in UTC vs GMT vs Zulu.

UTC to PST FAQ
UTC deploys to Pacific: subtract 8 hours for PST or 7 for PDT. Early UTC mornings often fall on the previous Pacific calendar date—check both columns.
Why can a UTC deploy timestamp show yesterday in Los Angeles?
Pacific is 8 hours behind UTC during PST and 7 hours behind during PDT. Early UTC mornings are still the previous Pacific evening—for example 04:00 UTC Tuesday = 8:00 PM PST Monday. Always read the date column.
How do I convert a CI/CD or cloud console time in UTC to Pacific?
Subtract 8 hours for PST or 7 hours for PDT. Example: 17:00 UTC is 9:00 AM PST or 10:00 AM PDT in Los Angeles.
Does UTC move when California springs forward?
No. UTC is fixed. Only the Pacific label moves PST↔PDT, narrowing the gap from 8 hours to 7. Calendar: U.S. DST 2026.
What is 06:00 UTC for West Coast on-call staff?
About 10:00 PM PST the prior evening (or 11:00 PM PDT). Global maintenance windows quoted in UTC often land overnight locally.
Which Pacific cities does this page cover—and is Phoenix included?
Pacific: Los Angeles, San Francisco, Seattle, Vancouver. Phoenix is not Pacific (most of Arizona stays on MST). See the Arizona DST guide.
Is this the same as a GMT-labeled notice to the West Coast?
Yes—GMT and Zulu are both UTC+0, so a maintenance notice written in either converts on this page unchanged. The one label that is not UTC+0 is BST: London wall clocks from late March to late October run an hour ahead. Details: UTC vs GMT vs Zulu.
Need UTC to Eastern or Central instead?
Open UTC to EST or UTC to CST.
