Questions
New York and San Francisco, explained
What is the time difference between New York and San Francisco?
San Francisco is 3 hours behind relative to New York, and this pair is unusual in that the gap does not change during the year.
Why does the difference between New York and San Francisco change?
It does not. Both cities observe daylight saving, but they change on the same dates and by the same amount, so the gap between them is preserved.
Does this account for daylight saving automatically?
Yes. Offsets come from your device's own copy of the IANA time zone database through the browser's Intl API, so they reflect whatever rules are current rather than a table bundled here that could go stale. Pick any date in the converter and it resolves that date's rules, not today's.
