Common questions

How many hours ahead is Shanghai of Las Vegas?

Shanghai is 15 hours ahead of Las Vegas right now. The gap is not fixed: it moves whenever either side changes its clocks.

What is the best time to call between Las Vegas and Shanghai?

There is no hour inside working hours in both cities. 17:00–18:00 your time (08:00 there) is the cheapest compromise, and one side is taking a shoulder hour.

Do Las Vegas and Shanghai change clocks on the same date?

Only one of them does, so the gap between them changes twice a year even though neither city moved relative to the sun.
