You could also just use regular expressions to accomplish a slightly simpler job if this is enough for you (e.g. as seen in [1]).

They are build in into javascript so you can use them without any libraries.

function isValidDate(dateString) {
  var regEx = /^\d{4}-\d{2}-\d{2}$/;
  return dateString.match(regEx) != null;
}

would be a function to check if the given string is four numbers - two numbers - two numbers (almost yyyy-mm-dd). But you can do even more with more complex expressions, e.g. check [2].

isValidDate("23-03-2012") // false
isValidDate("1987-12-24") // true
isValidDate("22-03-1981") // false
isValidDate("0000-00-00") // true
