Why people convert Toronto to Shanghai time
- Scheduling a call from Toronto to Shanghai: a 10:00 AM start in Toronto lands at 10:00 PM in Shanghai, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +12h gap: Toronto 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 9:00 PM in Toronto.

- Always state the zone abbreviation, not just the hour. "3:00 PM EDT" is unambiguous; "3 PM" across a +12h gap is not.
- With a +12h gap there is no shared 9-to-5 window, so alternate the early start: one week Toronto takes the early slot, the next week Shanghai does.
- Toronto: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +12h gap.
