Regular expression for date format- dd-mm-yyyy in Javascript

Question

I need a regular expression for date format: dd-mm-yyyy in Javascript.

Answer 1

'01-01-2012'.match( /(?!3[2-9]|00|02-3[01]|04-31|06-31|09-31|11-31)[0-3][0-9]-(?!1[3-9]|00)[01][0-9]-(?!10|28|29)[12][089][0-9][0-9]/ )

This looks for only valid dates from 1800 to 2099. No leap year support (as in it assumes every year is a possible leap year).
