Alberta Time will stay at UTC−06:00 through November
The province’s permanent-time change makes old winter conversions worth checking.
The new year-round arrangement
Alberta’s government states that it has adopted permanent Alberta Time, abbreviated ABT, at UTC−06:00. Beginning in November 2026, clocks will no longer return to Mountain Standard Time. This briefing explains the effect on scheduling; the government source provides the policy announcement. For Edmonton, people preparing winter appointments should avoid copying a conversion from an earlier winter, when the seasonal rules were different.
Names and offsets can tell different stories
The provincial name ABT and the abbreviation displayed by a software library may differ. IANA’s 2026c release models the new permanent offset and discusses its abbreviation choice. A display label alone is therefore a poor way to decide whether an appointment is correct. Check the numeric UTC offset, the date, and the intended location together. If a calendar still predicts a one-hour November rollback, investigate its time-zone data rather than assuming the provincial announcement is only a proposal.
Review cross-border schedules
Permanent local time does not guarantee a permanent difference from another jurisdiction. An overseas or US participant may still change clocks. For example, a meeting kept at a fixed Edmonton morning time may appear differently in another city after that city’s seasonal transition. Use the city comparison tool for the selected date, then verify any discrepancies against the organizer’s invitation and current official guidance.
What to check before sending invitations
Update devices and scheduling applications through their normal vendor channels. Inspect a future November event and a winter event, not just the current clock. If an old recurring series is wrong, preserve its intended Edmonton local time when correcting it and tell participants which occurrences are affected. Do not substitute a different city as a permanent workaround without understanding its history and future rules. Read recurring meetings and DST for the distinction between local-time and UTC-based schedules.
