Questions
Los Angeles and Shanghai, explained
What is the time difference between Los Angeles and Shanghai?
There is no single answer, which is why most converters get this wrong for part of the year. Shanghai is 15 hours ahead, 16 hours ahead relative to Los Angeles at different points in the year. Right now it is 15 hours ahead. The table on this page gives the exact dates for each.
Why does the difference between Los Angeles and Shanghai change?
Los Angeles moves between UTC-08:00 and UTC-07:00, while Shanghai stays on UTC+08:00 all year. A gap only stays fixed when both ends are fixed. Here one end moves, so the difference moves with it even though nothing changed at the other end.
When is the difference between Los Angeles and Shanghai unusual?
The shortest window runs from Sunday, 1 November 2026 to Saturday, 13 March 2027 — 133 days during which Shanghai is 16 hours ahead relative to Los Angeles rather than the usual amount. Short windows like this are where recurring meetings break, because nobody thinks to check.
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.
