Time difference between USA west coast and China

Does anyone know what the time difference is from here (USA West Coast) and China?

I have tried to figure it out and I’m too tired, stressed out and lazy.

Can anyone help? Ugh. I want to call a friend on their birthday today but don’t want to call & wake up the house
if it’s the middle of the night there. It’s their home phone. They were not able to bring their cell phone.

TIA

Current local time in china right now is 5:51 am. And I’m in CA.

.

Japan is 12 hours from me so depending on where they live it is 12-17 hours from me, East Coast.

China has 5 time zones.

I would wait a couple hours to be sure to call her in the daytime

OOPS I was just told that although CHina has 5 timezones they are on one time for the whole country, so it is now 6:22 in China no matter where they are. Sorry.

when I posted this it was 5:58AM in Shanghi.

LA time 6:00pm is 9:00am in China. So, it is safe to call after 6:00pm.
