About Calgary
Calgary is the largest city in the Canadian province of Alberta and the headquarters of much of Canada's oil and gas industry. It is also a gateway to the Rocky Mountains, with Banff National Park a short drive away, and it hosts the Calgary Stampede, one of the world's best-known rodeo and western festivals, every July.
Calgary keeps the same time as the rest of Alberta, on Mountain Time, which has been UTC-7 in winter and UTC-6 in summer. Alberta has been reviewing how it handles daylight saving time, so the time zone cards on this page always show the current offset and the next clock change straight from the official time zone database. For calls with the rest of Canada, mid-morning in Calgary usually catches both Toronto and Vancouver within office hours.
