Why people convert GST to Toronto time
- Scheduling a call from GST to Toronto: a 10:00 AM start in GST lands at 2:00 AM in Toronto, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: GST and Toronto 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 Toronto is 1:00 AM in GST.
- Keeping family and friends in sync: knowing that 8:00 PM in GST is 12:00 PM in Toronto makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM GST" is unambiguous; "3 PM" across a -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week GST takes the early slot, the next week Toronto does.
