Why people convert Halifax to Bogotá time

  • Scheduling a call from Halifax to Bogotá: a 10:00 AM start in Halifax lands at 8:00 AM in Bogotá, so you can confirm the slot without doing the arithmetic yourself.
  • Finding shared working hours: both Halifax and Bogotá are inside the 9-to-5 working day between 11:00 AM and 5:00 PM ADT time (9:00 AM–3:00 PM COT). That is roughly 6 hours of usable overlap.
  • Watching a live event or market open: Halifax viewers need 7:00 AM in Bogotá to catch a 9:00 AM start there, and 2:00 AM if the event is anchored to Halifax.
  • Always state the zone abbreviation, not just the hour. "3:00 PM ADT" is unambiguous; "3 PM" across a -2h gap is not.
  • Block 11:00 AM–5:00 PM ADT as the recurring meeting window if you work primarily from Halifax and need Bogotá colleagues present.
  • Halifax: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the -2h gap.
