I'm using Microsoft bookings and trying to set up an appointment time for one day as per image below.

Once the changes are saved, the bookings link is providing appointments for the wrong day - Wednesday instead of Tuesday.

Is this a user error or a bug?

Set the logged-in Bookings administrator’s Outlook time zone to (UTC+10:00) Brisbane, because the configured Tuesday 6:00–9:00 PM window is being converted from UTC into Wednesday 4:00–7:00 AM on the Brisbane-facing booking page.

The exact ten-hour shift in the screenshots indicates time-zone conversion, not an incorrect weekday selection:

  • Configured: Tuesday, December 1, 6:00–9:00 PM
  • Published in Brisbane: Wednesday, December 2, 4:00–7:00 AM

Bookings has two separate time-zone settings: one for the internal booking calendar, inherited from the logged-in user’s Outlook on the web settings, and another for the customer-facing booking page. ^1^

Correct both time-zone settings

  1. Sign in to Outlook on the web using the same account that edits this Bookings calendar.
  2. Select Settings (gear icon), search for time zone, and set Current time zone to (UTC+10:00) Brisbane.
  3. Select Save. This setting controls the time zone used by the internal Bookings calendar. ^1^
  4. Open Microsoft Bookings and select the relevant shared booking page.
  5. Go to Booking page → Change language and time zone settings.
  6. Set its time zone to (UTC+10:00) Brisbane, and select OK.
  7. Reopen the service, re-save the date-range availability, and test the published link in a private/incognito browser window.

The published page already says that its displayed times are in Brisbane, so the Outlook/internal calendar setting is the critical correction. The public page can otherwise convert availability into the visitor’s detected local time zone and potentially move a slot across a date boundary. ^2^

If it remains on Wednesday

Check the service and assigned staff settings:

  • Under Services → select the service → Availability options, confirm the special date range is 30/11/2026–06/12/2026 and uses Tuesday custom hours. Date-range availability overrides the service’s general availability. ^3^
  • Under Staff → select each assigned staff member, verify their working hours do not conflict with Tuesday availability. Staff can either inherit business hours or have custom hours. ^4^
  • If both time zones are Brisbane and a newly created test availability still shifts by exactly ten hours, capture screenshots of the two time-zone settings and the published result, then open a Microsoft 365 support request. That would indicate behavior not explained by the documented conversion settings.

This is therefore a configuration mismatch unless the problem persists after both Bookings time zones are aligned.

    Hi @David Chen

    I tried to reproduce the issue in my own Microsoft Bookings environment using the same configuration shown in your screenshot. However, the booking page correctly displays Tuesday as available in my environment. I was unable to reproduce the behavior you described.

    This suggests that the issue may be related to a setting or environmental difference rather than a general issue with this availability configuration. You may find this documentation helpful Shared Bookings Frequently Asked Questions | Microsoft Learn

    Could you help clarify the following?

    • What time zone is selected under Booking page > Region and time zone settings?
    • Is Always show time slots in business time zone enabled?
    • Does the same issue occur when you open the booking link in an InPrivate/Incognito browser window?
    • Is the time zone configured on your Bookings page the same as the local time zone of the device or computer you are using to access the booking link? If they are different, could you specify both time zones?

    I'm a fellow user, not a Microsoft representative, so I cannot directly investigate your Bookings environment. However, these additional details may help me narrow down the cause.
