City history
Founded at the confluence of the Bow and Elbow rivers as Mohkínstsis, Calgary evolved from a Mounted Police outpost to Alberta's energy hub, driven by railway synchronization and timekeeping milestones.
Chapter one
Indigenous name
"Elbow"
Refers to the distinct bend formed where the Elbow River joins the Bow River. The site was a long-standing gathering location for Blackfoot, Stoney Nakoda, and Tsuut'ina First Nations prior to European settlement.
Elbow
Traditional Blackfoot name for the confluence of the Bow and Elbow rivers. The site is also called Wîchîspa by the Stoney Nakoda and Guts'ists'i by the Tsuut'ina.
Named for Inspector Éphrem-Albert Brisebois
Assigned by North-West Mounted Police Inspector Éphrem-Albert Brisebois upon establishing the post in 1875. The name was discarded in 1876 due to internal disapproval.
Bay farm or meadow beach (Scottish Gaelic)
Suggested in 1876 by Colonel James Macleod after Calgary House and Bay on the Isle of Mull, Scotland, and approved by the federal Minister of Justice.
Incorporated town on the Bow River
Incorporated under North-West Territories ordinance in November 1884 following the arrival of the transcontinental Canadian Pacific Railway in 1883.
Incorporated city in Alberta
Incorporated as a full city in January 1894 under a territorial charter, eventually becoming the largest city in the province of Alberta.
Chapter two
The Canadian Pacific Railway introduced standardized Mountain Time across its western transcontinental lines on November 18, 1883, replacing local solar time in Calgary.
Calgary observed nationwide Daylight Saving Time for the first time during World War I following the federal government's enactment of the Daylight Saving Act of 1918.
Alberta voters passed a provincial plebiscite to officially adopt seasonal daylight saving time, establishing regular bi-annual clock adjustments across Calgary.
Calgary aligned with revised North American standards, extending daylight saving time from the second Sunday in March to the first Sunday in November.
In an October 2021 provincial referendum, 50.2% of Alberta voters chose to keep seasonal clock changes rather than adopt permanent year-round daylight time.
Chapter three
Lacking a public clock when incorporated in 1884, Calgary relied on retired Mounted Police officer James H. Walker to fire a cannon daily at noon to align town timepieces.
A Seth Thomas No. 16A four-faced mechanical clock was installed in Historic City Hall's tower, synchronized with railway time and serving as Calgary's central civic clock.
The University of Calgary inaugurated the Rothney Astrophysical Observatory near Priddis, equipped with research telescopes and a sundial for astronomical tracking.
Calgary Transit opened the CTrain light rail system on May 25, 1981, modernizing municipal transit and enforcing precise timetable scheduling across the city.
