Calling suppliers in Shenzhen from the West Coast

Silicon Valley hardware teams and Southern California importers work with factories across Guangdong, from Shenzhen's electronics suppliers to Dongguan's assembly lines. The shared slot is the California evening: 5:00 to 7:00 PM Pacific is 9:00 to 11:00 AM the next day in China in winter, and in summer the same China morning falls at 6:00 to 8:00 PM Pacific. Many West Coast buyers simply take supplier calls after dinner.

The ports of Los Angeles and Long Beach are the main US gateway for Chinese imports, so shipping cut-offs in China are watched closely in California. A container booking deadline of Friday 5:00 PM in Shenzhen is Friday 1:00 AM Pacific in winter, which effectively means Thursday night.

Writing China time without confusion

Write "Beijing time" or "UTC+8" rather than "CST", which most Americans read as US Central. China has one official time zone and no daylight saving, so the conversion depends only on whether the West Coast is on PST or PDT: the gap becomes 15 hours on the second Sunday of March and 16 hours on the first Sunday of November.

Shopping events show the gap well. Singles' Day sales open at midnight on November 11 in China, which is 8:00 AM on November 10 in California. National Day Golden Week, October 1 to 7, closes most offices, so expect slow replies for that whole week. For the East Coast version of this conversion, see China time to EST.
