>                 Key: VALIDATOR-221
>                 URL: https://issues.apache.org/jira/browse/VALIDATOR-221
>             Project: Commons Validator
>          Issue Type: Bug
>    Affects Versions: 1.3.1 Release
>         Environment: Windows XP, Java 1.5.0_04
>            Reporter: Carsten Drossel
>            Priority: Minor
>
> When the date pattern contains only day and month the isValid(..)-method of DateValidator returns false for the value Feb. 29th.
> Here is a JUnit test that fails:
> public void testFebruary29th() throws Exception {
>   assertTrue( DateValidator.getInstance().isValid( "02/29", "MM/dd", true ) );
> }
> The DateValidator uses the parse(..)-method of SimpleDateFormat for the validation. This method appears to complete any date using 01/01/1970 00:00. Since 1970 was not a leap year a ParseException is thrown for the input "02/29" with the format "MM/dd" because 02/29/1970 is not a valid date.
> But IMHO "02/29" should be valid. An example where it makes sense is a search for persons with a certain birthday.
