Why has Meta changed my date of birth on Facebook to the wrong one?

Anyone elae had this? It is still showing my original dob but I got this:

01-01-1970 is the start of Unix time or Epoch time. In computing terms it’s a universal reference point and time is counted in seconds before and after this.
This means that whenever there is some kind of glitch or system error it will set it as a default time

I don’t know but mine randomly changed last year, to about three weeks past my actual birthday. Was confused about why I got loads of birthday messages on the wrong day until I noticed.

meta deactivated my account..no rhyme or reason..im a tad annoyed

Not the point, but I’ve always had my date of birth as 1st Jan (real year of birth) on Facebook and hidden from friends as when it started I didn’t trust giving it all my real details. Wouldn’t really matter if it defaulted it a few years older. Maybe targeted advertising would vary?
