I did data recovery on an external drive in 2011. It was pretty bad but I only needed a dozen files or so, rest was backed up. One of the files restored had a borked creation time in May 2020. For some reason I never fixed that, so whenever I accessed that folder and sort by date, that file would be at the top. This is will stop happening soon. I grew so fond of this quirk that I'm almost sad.
It's probably going to take me about 2 months after the new year stop writing/entering "2019" on forms. And checks. And anything else that calls for a date.
Pretty much the same thing happens to me every year.
