fix: Date is not validated as expected

[sagepoudel]

The date is validated when the date is clearly not valid. You can put hyphen in the beginning of a date and it is treated as the right format.

Expected behavior

"-2012" not valid

Actual behavior

"-2012" valid

Working fine. Right?

[sagepoudel]

not really, was there a fix?

@sagepoudel I created a pull request for the fix #2381

This is the validation i added
// Check if the year starts with a hyphen
if (fullYear.startsWith('-')) {
return false; // Hyphen before year is not allowed
}
