If I recall correctly, this discussion was on how arbitrary dates could
be stored (eg. also historic and science fiction events), and there was
never any real consensus.
But solely for birthday purposes, the PHP-way must be the official way:

$ php -r 'print(strtotime("1960-12-21 23:10:15")."\n");'
-284867385
$ php -r 'print(date("Y-m-d H:i:s",-284867385)."\n");'
1960-12-21 23:10:15

This works back to sometime in 1901.
