British Columbia (Pacific Time) and Nova Scotia (Atlantic Time) are separated by 3 hours year-round.
| Region | Standard Time | Daylight Time |
|---|---|---|
| British Columbia | PST (UTC-8) | PDT (UTC-7) |
| Nova Scotia | AST (UTC-4) | ADT (UTC-3) |
Both observe DST simultaneously (second Sunday March → first Sunday November), maintaining the 3-hour difference.
Overlap window: 9 AM - 2 PM PT / 12 PM - 5 PM AT. Good for same-day collaboration. Avoid early PT / late AT or late PT / early AT.
Peace River Region (NE BC) uses Mountain Time year-round (no DST) — 2 hours behind rest of BC, 4 hours behind Nova Scotia. Creston (SE BC) also MST no DST.
