Alberta and British Columbia Share the Same Time Zone

There is no time difference between Alberta and British Columbia—with one important seasonal exception.

Standard Time (November–March)

Both provinces observe Mountain Standard Time (MST, UTC−7) during winter months. Clocks match exactly.

Daylight Saving Time (March–November)

Alberta observes Mountain Daylight Time (MDT, UTC−6). Most of British Columbia switches to Pacific Daylight Time (PDT, UTC−7)—so for ~8 months a year, BC is one hour behind Alberta.

Exceptions in BC

Peace River Region (northeastern BC, including Dawson Creek, Fort St. John) stays on MST year-round—matching Alberta always. East Kootenay (southeastern BC, including Cranbrook, Fernie) observes Mountain Time with DST, aligning with Alberta year-round.

Practical Impact

If you're scheduling a Calgary–Vancouver call in July: 10 AM Calgary = 9 AM Vancouver. In January: 10 AM Calgary = 10 AM Vancouver. Always confirm which time zone your BC contact follows.
