Why people convert Los Angeles to Shanghai time

  • Scheduling a call from Los Angeles to Shanghai: a 10:00 AM start in Los Angeles lands at 1:00 AM in Shanghai the next day, so you can confirm the slot without doing the arithmetic yourself.
  • Handling a +15h gap: Los Angeles 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 12:00 AM in Los Angeles.
  • Keeping family and friends in sync: knowing that 8:00 PM in Los Angeles is 11:00 AM in Shanghai makes it easy to avoid calling at 3 AM.
  • Always state the zone abbreviation, not just the hour. "3:00 PM PDT" 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 Los Angeles takes the early slot, the next week Shanghai does.
  • Los Angeles: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +15h gap.
