How do you make a kendo datepicker do date validation for a minimum date?

This code seems to work fine:

$("form").kendoValidator({
  rules: {
    dateValidation: function(element) {
      var value = $(element).val();

      var date = kendo.parseDate(value);
      if (!date) {
        return false;
      }

      return true;
    },
    minDate: function(element) {
      var value = $(element).val();

      var date = kendo.parseDate(value);

      var result = date >= new Date();

      return result;
    }
  },
  messages: {
    dateValidation: "You must enter a date",
    minDate: "The date must not be in the past"
  }
});
