Mac shows date as 04/01/1976?

After updating to Catalina 10.15.2, mail, calendar and FaceTime apps show date as 04/01/1976 when related to every date before yesterday.


Does anyone know how to solve this?

OK. I don't know the answer to this one. Hopefully, someone else can help.


That said, I suspect 04/01/1976 is the default 'reset' date.


Is this a MacBook Pro? If so, I wonder whether the internal battery is failing to keep the correct date and time.


If you disconnect the Internet temporarily and reboot, does the system date show as 04/01/1976 too? Then if you reconnect to the Internet, does it correct the system clock)? If so, this shows that the Mac is struggling to know the correct date and can only fix itself when the Internet is available.
