The live clock at the top of this page applies that offset to the current moment and refreshes every second.
What time zone is San Francisco in?
San Francisco uses the America/Los_Angeles time zone, shown as PDT. San Francisco uses UTC-8 in winter (standard time) and shifts to UTC-7 in summer when daylight saving time is active. The "compare to your time zone" section above converts any San Francisco time into your own local time instantly.
Does San Francisco observe daylight saving time?
Yes — San Francisco does observe daylight saving time. Clocks move forward one hour in summer, taking San Francisco from UTC-8 to UTC-7, and back again for winter. That means the difference between San Francisco and any place holding a fixed offset changes by an hour for part of the year. This page reads the current offset from the America/Los_Angeles zone data every time it loads, so the clock, the converter and the call window above are correct for today's date without you tracking the changeover.
How do I convert San Francisco time to my time zone?
Convert San Francisco time by taking its UTC-8 offset and applying the difference to your own: subtract San Francisco's offset from UTC to get the UTC time, then add your own offset. For example, 09:00 in San Francisco is 17:00 UTC. The converter above does this automatically after detecting your device's time zone, and the World Clock meeting planner lays several cities out on one colour-coded 24-hour grid.

What are the best hours to call San Francisco?
Standard business hours in San Francisco — 9:00 to 17:00 local time — correspond to 17:00 to 01:00 UTC while standard time is in effect, shifting one hour earlier in UTC terms during daylight saving. Convert that UTC window into your own zone to find the overlap. The "best time to call" line above does this for you, using waking hours of roughly 8am–9pm on both ends so neither side is called at night.
