What regular expression matches this pattern: 22-NOV-09

Question

I have tried:

/^([0-3][0-9])-(A-Za-z)-([0-1][0-9])?$/

and am not having success. What am I doing wrong?

Thank you folks!

Answer 1

/^([0-3][0-9])-([A-Z]{3})-([0-1][0-9])$/

EDIT : /^(0[1-9]|[1-2][0-9]|3[0-1])-([A-Z]{3})-(0[1-9]|1[0-9])$/
