UTC to PST
UTC and PST explained
Coordinated Universal Time (UTC) is UTC+0, the world's reference time, used by aviation, computing and science. UTC never changes for daylight saving. For everyday purposes it is the same as GMT.
Pacific Time uses PST (UTC−8) as standard time and PDT (UTC−7) during daylight saving time, from the second Sunday in March to the first Sunday in November; the clocks change at 2am local time. It covers the US west coast and British Columbia, including Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver. People often say "PST" all year; during daylight saving time the US west coast is on PDT.
The difference across the year
PT compared with UTC:
- 7 hours behind (UTC and PDT) from the second Sunday in March to the first Sunday in November
- 8 hours behind (UTC and PST) from the first Sunday in November to the second Sunday in March
PT changes its clocks and UTC doesn't, so the gap changes during the year. The converter above uses the rules for the date you pick.
Common times

How to use the converter
Pick a time and date under From; the time in PT appears under To, with your own local time underneath. The date matters around clock changes, so set it for the day you mean. ⇄ swaps the two zones, Now goes back to the current time, and either zone can be changed to any city. The planner below lines up the whole day in both places and in yours.
