what's stored in the database (SQL Server) as a Date or DATETIME column, is just a string formatted to a particular ISO format, labeled as something special or unique.

I needed a consistent way of working with dates already written, so I choose the ISO120 format. ISO120 just makes it easier to fabricate new dates, and do comparisons in PHP8.

I didn't want to change the database because it has 26 gigs of data.
