Why people convert Halifax to EST time

- Finding shared working hours: both Halifax and EST are inside the 9-to-5 working day between 11:00 AM and 5:00 PM ADT time (9:00 AM–3:00 PM EST). That is roughly 6 hours of usable overlap.
- Coordinating a Halifax-based team with EST 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 ADT" is unambiguous; "3 PM" across a -2h gap is not.
