Why people convert China to PDT time

  • Scheduling a call from China to PDT: a 10:00 AM start in China lands at 7:00 PM in PDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
  • Handling a -15h gap: China and PDT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in PDT is 6:00 PM in China.
  • Watching a live event or market open: China viewers need 6:00 PM in PDT to catch a 9:00 AM start there, and 3:00 PM if the event is anchored to China.
  • Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a -15h gap is not.
  • With a -15h gap there is no shared 9-to-5 window, so alternate the early start: one week China takes the early slot, the next week PDT does.

About CST (China Standard Time)

China Standard Time (CST, also known as Beijing Time) is used across all of mainland China despite the country spanning five geographical time zones. This single-timezone policy was adopted in 1949. China does not observe daylight saving time. CST is shared with Hong Kong (HKT), Macau, Taiwan, Singapore, Malaysia, and the Philippines, making UTC+08:00 one of the most used offsets in the world.

About PDT (Pacific Daylight Time)

Pacific Daylight Time (PDT) is observed from March to November on the Pacific coast. During PDT, the west coast is 7 hours behind UTC and only 2 hours behind the east coast's EDT.

Best time to call between China and PDT

With a -15h offset there is no overlap inside a normal 9 AM – 5 PM day. PDT opens at 9:00 AM PDT, which is 6:00 PM in China, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

China and PDT have no shared working hours because of the -15h gap. Teams need to alternate early starts or rely on asynchronous handovers.

China is 15 hours behind PDT (CST UTC+08:00 → PDT UTC-07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
