If that is meant to indicate a date in MM/DD/YY form that is a palindrome (the same backwards as forwards), as opposed to being strictly MM=DD=YY, there are plenty of dates yet to come before the next century. For example, 12/22/21 or 12/11/21.

And hey, 12-12-12 isn’t even a palindrome like 11-11-11 was. It’s just a triplet.

yes 11-11-11 is a palindrome and a palendri-cal phenomenon, but 12-12-12 is only a palendri-cal phenomenon.
