Is New York always 3 hours ahead of San Francisco?

Yes. New York is in Eastern Time and San Francisco is in Pacific Time. Because both cities switch to Daylight Saving Time on the same dates, the offset is a constant 3 hours throughout the year.

What time zones are used?

New York uses America/New_York (UTC-5 in winter, UTC-4 in summer). San Francisco uses America/Los_Angeles (UTC-8 in winter, UTC-7 in summer). The 3-hour gap between them never changes.

What is Eastern Time (ET)?

Eastern Time covers the US East Coast, including New York, Boston, and Miami. It is UTC-5 during Eastern Standard Time (EST) and UTC-4 during Eastern Daylight Time (EDT).

What is Pacific Time (PT)?

Pacific Time covers the US West Coast, including San Francisco, Los Angeles, and Seattle. It is UTC-8 during Pacific Standard Time (PST) and UTC-7 during Pacific Daylight Time (PDT).

Does Daylight Saving Time affect the offset?

No. Both New York and San Francisco observe Daylight Saving Time on the same dates (second Sunday in March to first Sunday in November), so the 3-hour gap between them stays constant.

How accurate are the clocks?

The clocks rely on your device's system clock and the browser's Intl.DateTimeFormat API with IANA time zone data. They are accurate to the second as long as your system time is correct.
