See the live UTC time next to the current time in Los Angeles, check today's real offset, and roll through any UTC time to find the matching PT time — including when the two zones fall on different dates.

Coordinated Universal Time (UTC) is the world's time standard: it never shifts for seasons and every other zone is described as an offset from it. US Pacific Time (PT) is the clock used in Los Angeles. Converting UTC to PT means adding that offset to the UTC reading.
Pacific Time covers California, Washington, Oregon and Nevada, and is the working clock for most US technology companies.
Take the UTC time, apply the current PT offset shown in the live panel above, and roll the date forward or back if the result crosses midnight. The interactive roller does all three steps for you: the left drum is UTC, the right drum is PT, and a day badge appears whenever the local date differs.
Because PT observes daylight saving time, the gap to UTC is not fixed — every clock and table on this page is calculated live from the America/Los_Angeles IANA database, so today's real offset is always what you see.
The reference table below the tool lists every UTC half hour against the matching PT time for today, so you can copy a conversion without touching the roller.
Pacific Time runs at UTC -08:00 as PST in winter and UTC -07:00 as PDT during daylight saving, roughly mid-March to early November.
