Day 2 of fetching data from external sources: someone entered an entry on 2006.41.12 (YYYY.MM.DD). People will do everything to fuck with API users

You don't validate the input?

@C0D4 Don't worry, the standard lib of the programming language I use threw an error me :)

Date handling, one if the few infinite sources of new kind of bugs ;)

I also had a form that required a date.

After trying to validate or convert a number of different formats the user wrote, yes user as in singular, she just could not write the date the same format twice, I finally gave up and replaced the date field with a date picker with no input field.

That actually solved the problem.
