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.

Birthdays in Contacts app on Mac one day off Hi, I am having an issue which almost drives me crazy I am synching contacts via an Exchange server, and all works well, i.e. new contacts as well as changes are being synched between all devices very quickly. Also, the birthday attribute is the same everywhere: Exchange Server (via browser) Outlook Contacts app on iPhone Contacts app on iPad EXCEPT in the Contacts App on the MacBook, there every birthday is one day too late (e.g. 1st of Jan 2023 instead of 31st of Dec 2022). The timezone settings however are the same and correct everywhere. What might be the problem?

Mac Calendar & contacts moving birthday ahead one late Experience: Looking at my Mac Calendar I noticed birthdays are showing one late. i.e 11/22 is showing up on 11/23. I viewed the contact in Contacts, sure enough it shows birthday at 11/23 (which is wrong), I switch it back to 11/22 using edit and save. Moments later it switches it back. ARRGGH. I do sync my Mac with Office 365, the contact in Office 365 shows the correct date of 11/22. Why does it have the wrong date? Why does it switch back?

Birthdays show one day late in MacOS, correctly in iOS (synced through Exchange) Since doing a fresh install of Big Sur, my contact birthdays show one day off (later) in Calendar and Contacts on my MacBook Pro. These are synced with Exchange. On my iPhone (iOS14.7.1) the birthdays are still correct (synced with the same Exchange server) and in Outlook on my Mac (also syncing with the same Exchange server). From a google search I see that many people have had this issue and it seems unresolved. I did not have it until my MacBookPro had a clean install with Big Sur. Any suggestions on how to solve this are welcome. So far I tried: checking the time zone settings; same for iOS and MacOS logging out of the exchange calendar account on MacOS and iOS; then logging in again adding new contacts on iPhone, MacOS Contacts and Outlook: iPhone and Outlook sync correctly, MacOS Contacts&Calendar is one day off for all. This means: adding a Contact with birthday on Big Sur makes it appear one day earlier on Outlook and iPhone Contacts/Calendar. Adding a contact with birthday through Outlook or iPhone makes it appear one day later on MacOS Contacts/Calendar.

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:

Maybe a question for the Microsoft product help communities.

Suggestion: check date/time with timezone in your mac.
