Why people convert PST to Shanghai time
- Scheduling a call from PST to Shanghai: a 10:00 AM start in PST lands at 2:00 AM in Shanghai the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +16h gap: PST and Shanghai 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 Shanghai is 1:00 AM in PST.
- Watching a live event or market open: PST viewers need 1:00 AM in Shanghai to catch a 9:00 AM start there, and 8:00 AM if the event is anchored to PST.
- Always state the zone abbreviation, not just the hour. "3:00 PM PST" is unambiguous; "3 PM" across a +16h gap is not.
- With a +16h gap there is no shared 9-to-5 window, so alternate the early start: one week PST takes the early slot, the next week Shanghai does.
