Turn a US Pacific Time reading into Coordinated Universal Time. The panels show both clocks live, and the roller lets you line up any PT time against its UTC equivalent.
US Pacific Time
Coordinated Universal Time
US Eastern Time
THE CLOCKS ABOVE ALWAYS SHOW THE LIVE CURRENT TIME. THE ROLLER BELOW IS A LOOKUP TOOL — ROTATING IT NEVER CHANGES THEM.
PT is 7 hours behind UTC
ET is 4 hours behind UTC
United States (Pacific) is 3 hours behind United States (Eastern)

US Pacific Time is the local clock in Los Angeles. Converting it to UTC removes the local offset so the time can be shared with anyone in the world without ambiguity — which is exactly why UTC is used for servers, aviation and international scheduling.
Pacific Time covers California, Washington, Oregon and Nevada, and is the working clock for most US technology companies.
Subtract the current offset shown in the offset panel from the local PT time. If the result goes below 00:00, UTC is still on the previous date. Use the roller to read the pairing directly instead of doing the arithmetic.
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.
Early-morning or late-night local times frequently sit on a different UTC date. The converter labels every selection as SAME DAY, NEXT DAY or PREVIOUS DAY so a deadline written in UTC is never off by 24 hours.
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.
