San Diego Time Zone: PST and PDT
Quick answer
San Diego uses Pacific Time, the same clock as Los Angeles, San Francisco and Sacramento.
To read the hour in San Diego, California accurately, select the city and its IANA time zone in a live clock. A date-aware clock accounts for seasonal changes where they apply. The dated examples below explain how the offsets work during different parts of 2026.
Which local time zone should you use?
For San Diego, use the IANA zone “America/Los_Angeles.” Its 2026 winter offset on January 15 is UTC−08:00, and its July 15 offset is UTC−07:00. The different offsets reflect a seasonal clock change; the offset for a specific future date must be calculated from that date.
Worked time examples with an exact date
A single UTC instant translates to different local clock readings. Each example starts at 2:00 p.m. UTC on the date stated, making seasonal differences easy to compare.
San Diego: January 15, 2026 → Thu Jan 15, 6:00 AM PST (UTC−08:00); July 15, 2026 → Wed Jul 15, 7:00 AM PDT (UTC−07:00).
For an additional post-DST comparison, November 15, 2026 at 2:00 p.m. UTC is Sun Nov 15, 6:00 AM PST (UTC−08:00) in San Diego. The offset is computed for that particular date.
How it compares with New York
| New York reference | Time in San Diego |
| January 15, 2026 at 9:00 AM ET | January 15 at 6:00 AM (PST) |
| July 15, 2026 at 9:00 AM ET | July 15 at 6:00 AM (PDT) |
| November 15, 2026 at 9:00 AM ET | November 15 at 6:00 AM (PST) |
As these dated conversions show, a time difference can change during the year if the two places use different daylight-saving rules. A 5 p.m. San Diego start is normally 8 p.m. in New York when both regions observe the standard US seasonal rules.
Useful scheduling checks
Avoid giving PST as a year-round label; San Diego observes PDT in the daylight-saving part of the year.
For a meeting, flight, livestream or delivery in San Diego, California, keep the city, local date and time-zone label together. A calendar invitation that includes the correct time-zone identifier can adjust for daylight saving automatically; a plain text message saying “3 PM” cannot.
A reliable way to read the current time
Choose a live clock configured to the correct IANA zone (for example, “America/Los_Angeles”), verify the displayed date as well as hour, and check whether the calendar event is fixed to a city or to your device’s time zone. A time-zone abbreviation without a date can be ambiguous around seasonal transitions.
