FAQ

How many hours apart are Shanghai and Rock Springs right now?
The answer at the top of the page is calculated for the current moment and states which side is ahead. The gap changes during the year, because the two places usually start and end daylight saving on different dates.
Is this difference the same all year?
Not necessarily. Shanghai uses Asia/Shanghai and Rock Springs uses America/Denver; if either observes daylight saving, the gap shifts during the year. Use “Convert a specific date and time” below to calculate it for a given day.
How do I read the conversion table?
The left column lists each whole hour in Shanghai; the right column is the local time in Rock Springs at that same instant, with date rollovers marked. On the day clocks jump forward, some hours do not exist locally — the table says so instead of showing a plausible but wrong value.
