There is no time difference between Calgary and Edmonton. Both cities use Mountain Time (MST, UTC-7 in winter and MDT, UTC-6 in summer). When it's 9:00 AM in Calgary, it's also 9:00 AM in Edmonton.
Both cities are in the province of Alberta and observe daylight saving time on the same schedule, so they remain synchronized year-round.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 5:00 PM) without any time conversion needed.
Calgary and Edmonton are Alberta's two largest cities, connected by a 3-hour drive along Highway 2. Calgary is known for its oil industry and the Stampede, while Edmonton is the provincial capital.
