Common questions

How many hours ahead is San Bernardino of Beijing?

San Bernardino is 15 hours behind Beijing right now. The gap is not fixed: it moves whenever either side changes its clocks.

What is the best time to call between Beijing and San Bernardino?

There is no hour inside working hours in both cities. 08:00–09:00 your time (17:00 there) is the cheapest compromise, and one side is taking a shoulder hour.

Do Beijing and San Bernardino 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.
