November 4, 2026
Alberta's new permanent time zone took effect on November 1, 2026. While most people no longer need to worry about changing their clocks twice a year, businesses should make sure their computers, calendars, and automated systems have adjusted correctly.
Alberta has officially moved to permanent Alberta Time (ABT), meaning the province will remain at UTC−6 year-round.
For businesses using Microsoft 365, automated phone systems, appointment scheduling software, and other time-sensitive technology, the transition may require updates or configuration changes.
If your business hasn't reviewed its systems yet, now is a good time to make sure everything is working as expected.
What Changed with Alberta Time?
Previously, Alberta switched between Mountain Standard Time (UTC−7) in the winter and Mountain Daylight Time (UTC−6) in the summer.
Under the new system, Alberta remains at UTC−6 throughout the year.
That means Alberta did not turn its clocks back on November 1, unlike many other jurisdictions across North America.
While the change simplifies timekeeping in the long run, some computers and applications may still be configured to follow the old Mountain Time rules.
The result? Appointments, automated tasks, and business systems could potentially operate one hour earlier or later than intended.
Here are four areas Alberta businesses should check following the transition.
- Make Sure Windows Computers Show the Correct Time
Microsoft has released Windows updates to accommodate Alberta's new time zone.
Computers that have received the appropriate updates and are configured correctly should display the proper time. However, devices that haven't been updated may still follow the old daylight saving time rules.
This can affect more than the clock in the corner of your screen. Applications that rely on Windows time-zone information may also be affected.
What to check:
- Open Settings > Time & language > Date & time.
- Confirm your computer displays the correct local time.
- Verify that the appropriate Alberta time zone is selected.
- Check for outstanding Windows updates.
If your computer shows the wrong time or doesn't offer the new Alberta time zone, contact your IT provider rather than manually adjusting the clock.
- Review Outlook Calendars and Upcoming Meetings
Microsoft has introduced a new time-zone selection for Alberta:
(UTC-06:00) Mountain Time (Alberta)
Businesses using Microsoft Outlook should confirm their calendar settings reflect the new time zone.
Appointments and recurring meetings created before the transition deserve particular attention, especially those involving participants outside Alberta.
Potential problems include:
- Client appointments appearing an hour earlier or later than intended.
- Recurring staff meetings displaying incorrect times.
- Microsoft Teams meeting invitations showing inconsistent times.
- Scheduling confusion between employees, customers, and contractors.
Microsoft has also cautioned that changing the time zone of a recurring meeting series can reset previously modified individual occurrences.
What to check: Open your Outlook calendar settings and confirm that the new Alberta time zone is selected where available. Review important upcoming meetings and recurring appointments for accuracy.
If you notice discrepancies, have the meeting organizer or your IT provider review them before making changes.
- Verify Microsoft Teams Phone System Schedules
Businesses using Microsoft Teams for their phone systems should pay particular attention to automated call routing.
Microsoft has advised that Teams auto attendants configured with the old Mountain Time (US & Canada) setting require a manual adjustment.
Its current guidance for affected Alberta organizations is to use:
(UTC-06:00) Saskatchewan
This is important because automated phone systems often rely on schedules to determine whether incoming calls should go to reception, voicemail, or an after-hours service.
An incorrect time-zone setting could cause calls to be routed incorrectly.
For example, a business that opens at 8:00 AM could find its phone system still following an after-hours schedule.
What to check: Ask your IT provider to verify your Teams auto attendant settings, business hours, holiday schedules, and after-hours call routing.
- Don't Forget Other Business Systems
Microsoft 365 isn't the only technology that could be affected by Alberta's time change.
Any software or equipment that relies on time-zone settings or scheduled activities may need attention.
Examples include:
- Online appointment booking systems.
- Employee scheduling and time-tracking software.
- Automated backup and maintenance schedules.
- Building access-control systems.
- Security systems with scheduled activation times.
- Third-party business applications.
Not all these systems will experience problems. Some automatically adjust using updated time-zone information, while others may require manual configuration.
For businesses coordinating with customers, suppliers, or employees outside Alberta, it's particularly important to confirm that scheduled activities are being interpreted correctly across different time zones.
What to check: Review your business-critical scheduling systems and confirm that appointments, automated tasks, and time-based activities are occurring when expected.
Alberta Time Change: Your Business Checklist
Now that Alberta's new time zone is in effect, use this checklist to confirm your business systems are operating correctly.
For Employees
- Check your computer's clock. Confirm your Windows computer displays the correct Alberta time.
- Verify your time-zone settings. Check that Windows is configured for the appropriate Alberta time zone.
- Review Windows updates. Install available updates according to your company's IT policies.
- Check Outlook. Confirm your calendar is using (UTC-06:00) Mountain Time (Alberta), where available.
- Review upcoming appointments. Double-check important meetings and recurring appointments, especially those involving people outside Alberta.
- Report scheduling problems. If an appointment appears at the wrong time, notify your IT provider before changing or recreating the invitation.
For Business Owners and Office Managers
- Confirm employee computers are updated. Check with your IT provider that the appropriate Windows time-zone updates have been applied.
- Verify automated phone schedules. Ensure calls are being routed correctly during and outside business hours.
- Review appointment booking systems. Confirm customer bookings and employee schedules display the correct times.
- Check automated business processes. Verify that backups, maintenance tasks, access controls, and other scheduled systems are running as expected.
- Confirm scheduling with outside contacts. Pay particular attention to meetings and appointments involving other provinces or time zones.
Important: If your computer or an application is displaying the wrong time, avoid manually adjusting the system clock to compensate. Incorrect clock settings can create additional problems with applications and network authentication. Contact your IT provider to correct the underlying configuration.
A Small Time Change That Could Cause Big Scheduling Problems
Alberta's move to permanent Alberta Time should make scheduling simpler over the long term. However, the transition is a reminder that even relatively small changes can have unexpected effects on business technology.
A missed appointment, an automated phone system switching to after-hours mode at the wrong time, or a scheduled task running an hour late can all affect productivity and customer service.
The good news is that most potential problems can be identified and corrected with a straightforward review of your systems.
