Fix Microsoft Bookings Daylight Saving Time in Central Europe
Question details
The user needs Microsoft Bookings to automatically adjust appointment times for Daylight Saving Time (summer time) in Central Europe.

- Product
- Microsoft Bookings
- Device & OS
- not provided
- Scenario
- Scheduling client appointments in a region that observes Daylight Saving Time, where appointments might incorrectly display due to a fixed time zone offset.
- Observed behavior
- Appointments fail to adjust automatically for summer time because the booking page is configured using a fixed UTC offset instead of a location-based time zone.
Ensure you have administrative or owner access to the Microsoft Bookings calendar you wish to modify, and know the specific Central European city that matches your business hours.
Change to a Location-Based Time Zone
Switching your booking page from a fixed UTC offset to a specific city-based time zone ensures automatic Daylight Saving Time adjustments.
When Microsoft Bookings is configured with a fixed offset (such as UTC+1), the calendar remains static throughout the entire year. To allow the system to automatically shift appointments forward or backward by an hour when Daylight Saving Time begins or ends, you must select a specific city that observes these changes.
Log in to your Microsoft 365 account, open the Bookings application, and navigate to the 'Booking page' tab on the left-hand navigation menu.
Scroll down the page until you find the 'Region and time zone settings' section, and click to expand its options.
Click the 'Current time zone' dropdown menu. Instead of choosing a generic fixed setting like 'UTC+1', search for and select a location such as 'Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna'.
Click 'Save' at the top of the screen. To confirm the fix, open your published booking page link on another device or browser to ensure that available appointment slots are displaying correctly.

Frequently Asked Questions
Why do my appointments show up an hour off after the summer time switch?
This usually happens when your booking page is set to a fixed UTC offset (like UTC+1). Fixed offsets do not recognize the shift to summer time. You must switch to a location-based time zone, such as Amsterdam or Berlin, in your Bookings settings.
How can I accurately check if my customers are seeing the correct appointment times?
You can copy your booking page URL and open it on a different device or within an incognito/private browsing window. For the best test, view calendar dates that fall after the Daylight Saving Time change.
Does Microsoft Bookings automatically detect the customer's time zone?
Yes, if the 'Always show time slots in business time zone' option is unchecked, Bookings will detect the customer's local time zone based on their browser settings and display the available slots in their local time.
