Calgary keeps Mountain Time, the zone covering Alberta and much of the western interior of North America. The city uses Mountain Standard Time (UTC-7) in winter and Mountain Daylight Time (UTC-6) in summer, switching on the standard March and November dates shared with the US. As Alberta's largest city and a major energy industry hub, Calgary sits two hours behind Toronto. Since Vancouver adopted year-round UTC-7 in 2026, Calgary matches Vancouver in winter and is one hour ahead in summer. When it is noon in Calgary, it is 2 p.m. in Toronto.
Calgary changes its clocks for daylight saving time, so its exact UTC offset depends on the season (UTC-7 (UTC-6 in summer)). The live clock above reads Calgary's local time directly from the IANA time zone database in your browser, using the rules installed on your device.

Calgary sits at about 51.0°N, 114.1°W. The longest day of 2026 is June 17, with 16h 33m between sunrise and sunset. The shortest is December 19, with 7h 54m, a difference of 8 h 39 min. This far from the equator the swing is large: winter days are short and summer evenings stay light very late.
The earliest sunrise of the year comes around June 16 (05:20) and the latest sunset around June 23 (21:55). These are not exactly on the solstice because the sun’s position runs slightly ahead of or behind clock time during the year.
Solar noon, when the sun is highest, falls at about 13:43 local time in late March, 13:38 in late June and 13:34 in late December.

During daylight saving time everything moves an hour later on the clock.
