Time in San Francisco Now — Current Local Time. San Francisco is on UTC−08:00 right now — San Francisco is on UTC−08:00 in winter and UTC−07:00 in summer, when daylight saving is in effect. The current local time, date and daylight saving status are shown live by the world clock, which is worked out from the IANA time zone database (America/Los_Angeles), not from a printed table.

What time is it in San Francisco now?
The world clock shows the current time in San Francisco live — the time, the date and the day of the week — updated every second from your device's clock and the IANA time zone database. It is the time in the America/Los_Angeles zone, which covers San Francisco and the surrounding region. The clock does not use a fixed offset: it asks the database what the offset is on today's date, so it is right whether daylight saving is in effect or not. That matters more than it sounds, because San Francisco's offset changes twice a year, and a table printed in January would be wrong in July.
If you need the time in San Francisco for a meeting or a flight, use the live clock rather than a remembered offset. The remembered offset is right most of the year and wrong for a few weeks — the weeks when San Francisco changes its clocks and the place you are calling from has not yet, or has already. The time zone converter handles the date as well as the cities, so it is right on the awkward dates too.
San Francisco's UTC offset
San Francisco is on UTC−08:00 in winter and UTC−07:00 in summer, when daylight saving is in effect.
| Period | Offset | In effect |
|---|---|---|
| Standard time | UTC−08:00 | Late autumn to early spring |
| Daylight saving time | UTC−07:00 | From 8 March 2026 to 1 November 2026 in 2026 |
| Right now (11 November 2026) | UTC−08:00 | Standard time is in effect |
The offset is the whole story for conversions. To get the time in San Francisco from UTC, add the offset: when it is 12:00 UTC, it is 04:00 in San Francisco in January and 05:00 in July. To go the other way, subtract it. The UTC converter does the arithmetic for any hour, and the UTC to San Francisco page has the full 24-hour conversion table for this city.
Daylight saving in San Francisco
San Francisco observes daylight saving time. In 2026 the clocks go forward on Sunday, 8 March 2026 and back on Sunday, 1 November 2026; in 2027 the clocks go forward on Sunday, 14 March 2027 and back on Sunday, 7 November 2027. The offset moves from UTC−08:00 to UTC−07:00 and back again.
The change happens at 2am local time in most places that observe it: the clocks jump to 3am in spring, so the hour from 02:00 to 03:00 does not exist, and fall back to 1am in autumn, so the hour from 01:00 to 02:00 happens twice. If you are scheduling across the change, check the date — a meeting set for 02:30 on the change day does not exist in spring, and is ambiguous in autumn. The daylight saving checker shows the exact dates for any zone, and the San Francisco DST 2026 page has the full story for this city.
San Francisco working hours in other cities
The table below converts San Francisco's working day — 09:00 to 17:00 local time — into the time in four reference points: UTC, New York, London and Tokyo. It is the table to use when you are working out whether someone in San Francisco is at their desk.
January (northern winter) — when it is the time in the first column in San Francisco, it is the time shown in each other city.
| Time in San Francisco | UTC | New York | London | Tokyo |
|---|---|---|---|---|
| 09:00 | 17:00 | 12:00 | 17:00 | 02:00 |
| 12:00 | 20:00 | 15:00 | 20:00 | 05:00 |
| 15:00 | 23:00 | 18:00 | 23:00 | 08:00 |
| 17:00 | 01:00 | 20:00 | 01:00 | 10:00 |
July (northern summer) — when it is the time in the first column in San Francisco, it is the time shown in each other city.
| Time in San Francisco | UTC | New York | London | Tokyo |
|---|---|---|---|---|
| 09:00 | 16:00 | 12:00 | 17:00 | 01:00 |
| 12:00 | 19:00 | 15:00 | 20:00 | 04:00 |
| 15:00 | 22:00 | 18:00 | 23:00 | 07:00 |
| 17:00 | 00:00 | 20:00 | 01:00 | 09:00 |
Read the table from left to right: find the time in San Francisco, then read across to see what time it is in each other city. If the January and July tables differ, the difference is daylight saving — one or more of the cities has changed its clocks between the two dates. The meeting planner does the same conversion for any two cities and any date, and the meeting time finder finds the hours when everyone is available.
Best time to call San Francisco
The best windows to call San Francisco — the hours when San Francisco is in its working day and New York, London and Tokyo are most likely to be awake — are 00:00–10:00 San Francisco time, 19:00–24:00 San Francisco time (January, when the offsets are as shown in the table above). These are the hours when at least two of the three hubs are between 07:00 and 22:00 local time, so the call is inside the working day in San Francisco and at a reasonable hour for the other side. Outside these windows, the call is either before the working day in San Francisco or in the middle of the night somewhere else.
As a rule of thumb, the kindest time to call San Francisco from the United States is late morning in New York, which is the afternoon or evening in San Francisco for most of the world east of the Atlantic — and the kindest time from Europe is mid-morning in London, which is late morning or afternoon in San Francisco for most of Asia. The worst time to call is the hour that is 03:00 somewhere: check the tables above before you dial.
About San Francisco and its time zone
San Francisco is on Pacific Time — UTC−08:00 in winter, UTC−07:00 in summer. It shares its zone with Los Angeles, so the two cities are always on the same time, even though they are 600 kilometres apart.
San Francisco is in the Americas region, and its IANA time zone is America/Los_Angeles. That name is the identifier computers use: when your phone, your calendar or this website works out the time in San Francisco, it looks up America/Los_Angeles in the IANA Time Zone Database and applies the rules for that zone on the date you asked about. The rules include the standard offset, the daylight saving dates and the whole history of changes — which is why the answer is right even for dates in the past, when the rules were different.
The practical consequence is that the time in San Francisco is not a fixed number. It is two numbers — the winter offset and the summer offset — and which one applies depends on the date. Any tool that only knows one of them will be wrong for half the year. The time zone list shows every zone in the database with its current offset, and the guides explain how the system works.
San Francisco compared with the world's major cities
When it is 12:00 in San Francisco, it is:
| City | January | July |
|---|---|---|
| New York | 15:00 | 15:00 |
| London | 20:00 | 20:00 |
| Paris | 21:00 | 21:00 |
| Dubai | 00:00 | 23:00 |
| Mumbai | 01:30 | 00:30 |
| Singapore | 04:00 | 03:00 |
| Tokyo | 05:00 | 04:00 |
| Sydney | 07:00 | 05:00 |
The January and July columns differ wherever one of the cities observes daylight saving and the other does not, or where they change their clocks on different dates.

How to convert San Francisco time
Three worked examples, all for January, when San Francisco is on UTC−08:00: 09:00 in San Francisco is 17:00 UTC, 17:00 in London and 12:00 in New York. 12:00 in San Francisco is 20:00 UTC and 05:00 in Tokyo. 17:00 in San Francisco — the end of the working day — is 01:00 UTC and 20:00 in New York. In July, when San Francisco is on UTC−07:00, add or subtract the difference between the two offsets — 1 hour — from each of those answers.
