Sunrise & Sunset Times in Calgary — October 2027

Sunrise & Sunset in Calgary During October

October in Calgary brings a pronounced shortening of days as the sun's arc drops lower. Sunrise arrives later each morning and sunset comes markedly earlier, with the total daylight loss accelerating through mid-month before easing slightly. Where daylight saving time ends in October, the clock change shifts an hour of evening light to the morning. Civil twilight contracts, and by month's end, darkness arrives early enough to reshape daily routines.

Golden Hour & Twilight in October

During October, golden hour in Calgary lasts approximately 61 minutes each morning and evening. The low sun angle during these periods produces warm, directional light prized by photographers and filmmakers.

Through October, days in Calgary are shortening by roughly 3.8 minutes per day, adding up to about 1h 53m over the course of the month.
