Current Time in San Francisco
How to Check Current Time in San Francisco, United States
Open the San Francisco time converter page: Go to https://www.xconvert.com/time-converter/united-states/san-francisco to load San Francisco pre-selected on the comparison grid. This page is useful when you need the current time in California before scheduling a sales call with a Bay Area software company, confirming a support handoff with a West Coast team, or checking whether a traveler has landed at San Francisco International Airport during local business hours.
Add comparison cities with the “+ Add City” button: Click + Add City and search for cities such as New York, London, and Tokyo to compare San Francisco with major finance, tech, and manufacturing hubs. This is especially practical for remote teams working with Silicon Valley startups, UK clients, or Asia-Pacific suppliers, because San Francisco often sits at the end of the global workday overlap.
Drag across the grid to select a meeting window: Click Select if needed, then drag on San Francisco’s row from 9 AM to 11 AM to highlight a purple range, and use the side handles to fine-tune the window. For example, 9 AM to 11 AM in San Francisco is 12 PM to 2 PM in New York, 5 PM to 7 PM in London during standard offset periods, and 2 AM to 4 AM the next day in Tokyo, which quickly shows why US-East and UK calls are easier than Japan calls during a California morning.
Export or share the selected time range: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is helpful if you want to send a calendar hold to a distributed product team, paste a confirmed support window into Slack, or generate a shareable link so clients in other time zones see the San Francisco meeting slot in their own local time automatically.
About San Francisco Time Zone
San Francisco uses the IANA time zone America/Los_Angeles, which covers most of California and the US Pacific Time region. The city operates on Pacific Time, with a standard offset of UTC-8 during the winter and UTC-7 during daylight saving time in the warmer part of the year. Because San Francisco is a major technology and venture capital center, accurate Pacific Time conversion matters for software releases, investor meetings, cloud operations, and customer support schedules.
Daylight saving time in San Francisco follows the US federal schedule. In 2025, clocks move forward on March 9, 2025, changing from PST (UTC-8) to PDT (UTC-7), and move back on November 2, 2025, returning to standard time. This seasonal shift changes overlap windows with Europe, Asia, and even other North American offices, so a meeting that works in February may shift by an hour relative to London or Dubai after the DST transition.
Within the United States, San Francisco is 1 hour behind Mountain Time, 2 hours behind Central Time, and 3 hours behind Eastern Time. Nearby West Coast cities such as Los Angeles, San Diego, Seattle, Portland, Vancouver, and Las Vegas align with San Francisco for most business scheduling because they share Pacific Time, while cities like Denver, Chicago, and New York require cross-zone planning for same-day meetings and market activity.
San Francisco City Details
San Francisco is a major coastal city in California, United States, with a population of 864,816. It is located at 37.77493° latitude and -122.41942° longitude on the northern end of the San Francisco Peninsula, facing the Pacific Ocean and San Francisco Bay. This location places it in one of North America’s most important economic corridors, closely connected to Silicon Valley, Oakland, San Jose, and major Pacific air routes.
The local currency is the US dollar (USD), which is used for all retail, hotel, transport, and business transactions in the city. The country dialing code is +1, the same as the rest of the United States, so international callers typically dial +1 followed by the area code and local number. These details are useful for travelers booking hotels, companies issuing invoices, and international teams arranging calls with offices or partners in the Bay Area.
Time Differences from San Francisco
San Francisco’s time difference depends on whether Pacific Time is on standard time or daylight saving time, but the city is consistently one of the latest major business hubs in the global day. Compared with key international cities, the practical scheduling impact is significant for finance, software development, logistics, and customer support.
- New York: San Francisco is 3 hours behind New York. When it’s 9:00 AM in San Francisco, it’s 12:00 PM in New York, making late morning in California a common overlap for East Coast meetings, legal reviews, and cross-office sales calls.
- London: San Francisco is usually 8 hours behind London when both regions are on their typical seasonal clocks, though the gap can briefly shift to 7 hours around DST transition weeks because the US and UK change clocks on different dates. When it’s 9:00 AM in San Francisco, it is commonly 5:00 PM in London, which is often the last practical hour for live calls with UK teams.
- Tokyo: San Francisco is typically 17 hours behind Tokyo during Pacific Standard Time and 16 hours behind during Pacific Daylight Time. When it’s 9:00 AM in San Francisco, it is usually 2:00 AM or 1:00 AM the next day in Tokyo, so California mornings rarely work for Japan unless one side accepts off-hours scheduling.
- Sydney: San Francisco is generally 19 hours behind Sydney during many parts of the year, although the gap can vary between 17 and 19 hours because Australia and the US follow different DST calendars. When it’s 9:00 AM in San Francisco, it is often 4:00 AM the next day in Sydney, which means San Francisco late afternoon is usually better for Australia coordination.
- Dubai: San Francisco is 12 hours behind Dubai during Pacific Daylight Time and 11 hours behind during Pacific Standard Time because Dubai stays on UTC+4 year-round and does not observe DST. When it’s 9:00 AM in San Francisco, it is 9:00 PM or 8:00 PM in Dubai, making early California mornings one of the few same-day overlap windows for Gulf-region business.
Frequently Asked Questions
What time zone is San Francisco in?
San Francisco is in the America/Los_Angeles time zone, which is the official IANA time zone identifier for the city and the broader Pacific Time region of the western United States. In everyday use, this means Pacific Standard Time (PST, UTC-8) in winter and Pacific Daylight Time (PDT, UTC-7) in daylight saving months.
Does San Francisco observe daylight saving time?
Yes, San Francisco observes daylight saving time under US rules. In 2025, clocks move forward on March 9 and move back on November 2, so the city changes between UTC-8 and UTC-7 depending on the season. This matters for international scheduling because the time gap with London, Sydney, and other cities can temporarily shift during the weeks when DST dates do not align.
What is the time difference between San Francisco and New York?
San Francisco is 3 hours behind New York year-round because both cities observe US daylight saving time on the same schedule. For example, when it is 9:00 AM in San Francisco, it is 12:00 PM in New York, and when it is 5:00 PM in San Francisco, it is 8:00 PM in New York. This makes California mornings and early afternoons the most practical windows for coast-to-coast business calls.
What is the best time to call San Francisco from the US or UK?
From within the US, the best time to call San Francisco depends on your coast. If you are on the East Coast, calling between 12 PM and 3 PM Eastern usually reaches San Francisco between 9 AM and 12 PM Pacific, which aligns with normal office hours for tech firms, law offices, and service providers. From the UK, a good window is usually 4 PM to 6 PM London time, which corresponds to 8 AM to 10 AM or 9 AM to 11 AM in San Francisco depending on seasonal clock changes.
What is the UTC offset for San Francisco?
San Francisco has a standard UTC offset of UTC-8 and a daylight saving offset of UTC-7. The winter abbreviation is PST, while the summer abbreviation is PDT. If you are converting deadlines, flight arrivals, or remote work schedules, always check whether the date falls before or after the March and November DST changes.
What currency does San Francisco use?
San Francisco uses the US dollar (USD) because it is part of the United States. Travelers, international contractors, and business visitors should expect pricing, payroll, invoices, and card transactions to be denominated in USD, whether they are paying for hotels near Union Square, conference services in SoMa, or transportation to and from SFO.
Is San Francisco the same time as Los Angeles?

Both cities follow Pacific Time and switch between PST (UTC-8) and PDT (UTC-7) on the same dates, so there is no time difference between them. This is useful for travel planning along the California coast and for companies coordinating meetings between Bay Area and Southern California offices.
