Common questions

How many hours ahead is Mexicali of Shanghai?

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

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 Shanghai and Mexicali 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.
