Why people convert HST to Toronto time
- Scheduling a call from HST to Toronto: a 10:00 AM start in HST lands at 4:00 PM in Toronto, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both HST and Toronto are inside the 9-to-5 working day between 9:00 AM and 11:00 AM HST time (3:00 PM–5:00 PM EDT). That is roughly 2 hours of usable overlap.
- Coordinating a HST-based team with Toronto contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM HST" is unambiguous; "3 PM" across a +6h gap is not.
- Block 9:00 AM–11:00 AM HST as the recurring meeting window if you work primarily from HST and need Toronto colleagues present.
- Toronto: Clocks fall back on Sun, Nov 1, 2026. Any meeting series spanning that date will shift by an hour in local time.
