Why people convert Toronto to KST time

Scheduling a call from Toronto to KST: a 10:00 AM start in Toronto lands at 11:00 PM in KST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +13h gap: Toronto and KST 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 KST is 10:00 PM in Toronto.
Booking travel or deliveries: tracking KST local time against Toronto keeps pickup windows and arrival estimates honest across the +13h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM EDT" is unambiguous; "3 PM" across a +13h gap is not.
With a +13h gap there is no shared 9-to-5 window, so alternate the early start: one week Toronto takes the early slot, the next week KST 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 +13h gap.
