MacOS contact app - birthdays one day off with Microsoft Exchange

ISSUE

My contacts and calendar are synced by my Microsoft 365 Outlook account.


• The Birth Dates of my contacts are WRONG by 1 day in CONTACTS & CALENDAR apps on my MacBook 

• That same contact's Birth Dates are displayed CORRECTLY in CONTACTS & CALENDAR apps on my iPad, iPhone and in the Microsoft website.


Please advise how this can be fixed.

MacBook, macOS 11.5

This is a "known" issue on macOS, it has been this way at least since macOS 10.13 High Sierra.

Please file an Apple feedback (bug report) or open an Enterprise ticket if you can (opening a ticket for this is on my To Do list).

If you are not familiar with the previous two options, use this form instead:
