    Nice exercise, but the tests don't cover all possible "corner cases". As a result some solutions that don't follow the description are accepted.
    Things the tests don't check:

    • String with 2-digits Years should be accepted
    • Strings where the Month or the Day is '00' should be rejected
    • Strings where the last 4 characters contain something different from numbers should be rejected
  • Custom User Avatar

    this will accept "00" as a valid month or as a valid day.
