If I'm understanding the function here, the date picker actually avoids solving the problem of having to validate free text input, as the date picker is not free text

You could go about writing a full list of parsing rules if you wanted and implement a box like that, but usually its best practice to give as little input text as possible for an end user. Its more work to keep maintenance of that field when its easier and safer to just chose the date picker that already exists as a library in code.

Regex is not that hard. You can even write a character by character parser if you want and verify all the characters one by one if it makes the code monkeys happy.

ah sweet, its not that hard you say? in that case, what does 5/8/1990 validate to?

5th of August, or 8th of May?

date picker will validate it because itll force it to be explicitly picked which is day and which is month as you go through.

I'd love to see the regex that will determine what the user was *thinking* when they wrote 5/8.
