I wish this helpful for you I'm using the jQuery.validate plugin to validate inputs for my user registration form. , Something like :
code :
  function validate(string) {
    var re = /^[\u3300-\u9fff\uf900-\ufaff]{2,}$/;
    return string.length >= 6 || string.match(re);
  }

  validate("pat")
  validate("patate")
  validate("中")
  validate("中国")
Validate date in dd/mm/yyyy format using JQuery Validate

Validate date in dd/mm/yyyy format using JQuery Validate

this will help You don't need the date validator. It doesn't support dd/mm/yyyy format, and that's why you are getting "Please enter a valid date" message for input like 13/01/2014. You already have the dateITA validator, which uses dd/mm/yyyy format as you need.
Just like the date validator, your code for dateGreaterThan and dateLessThan calls new Date for input string and has the same issue parsing dates. You can use a function like this to parse the date:
code :
function parseDMY(value) {
    var date = value.split("/");
    var d = parseInt(date[0], 10),
        m = parseInt(date[1], 10),
        y = parseInt(date[2], 10);
    return new Date(y, m - 1, d);
}

wish help you to fix your issue as a possible UI solution: don't show a MessageBox if date is invalid but add an ErrorProvider control to Form and set errors description to Max and Min textboxes. Error provider will show Error icon if there are incorrect data and hide it when input is acceptable
code :
private void Max_TextChanged(object sender, EventArgs e)
{
     DateTime date;

     if (!DateTime.TryParse(Max.Text, out date))
     {
        formErrorProvider.SetError(this.Max, "The Date you entered is in invalid format");
     }
     else if (date > DateTime.Parse(AvailableMax.Text))
     {
        formErrorProvider.SetError(this.Max, "The Date you entered is out of range");
     }
     else
     {
        formErrorProvider.SetError(this.Max, string.Empty);
        ToDate.MaxDate = date;
        ToDate.Value = date;
     }
}

I wish did fix the issue. You'll have to create a custom method to jquery-validator and use this in your validation rules
This is what your custom method will be (I am assuming you've added a class class="date" in your field)
code :
<script type="text/javascript">
    $(document).ready(function() {
    $.validator.addMethod("ifDateInCurrentYear", function(value, element) {
        var date= $('.date').val();
   if(Date.parse(date).getFullYear() - new Date().getFullYear() == 0)
      return true;
   else return false;
    }, "* Date is not valid");

});
</script>
$(".order-dates").each(function (item) {
$(this).rules("add", {
    required: true,
    date: true,
    ifDateInCurrentYear : true;
});
});

With these it helps How to validate user if input end date is more than 3 days from the input start date? , Use this code to compare two dates
code :
function today()// it will get date of today
{
    return date("Y-m-d");

}
function last_three_day()//it will get date of last third day
{
    return date("Y-m-d",strtotime("-3 days"));

}


$date = date('Y-m-d',strtotime('2018-03-01')); //it is your date which you want to compare


if($date >= last_three_day() && $date <= today())
{
    echo "yes";
}
<?php

if(isset($_POST['submit']))
{
    $leaveFrom = date_create($_POST['leaveFrom']);
    $leaveTo =  date_create($_POST['leaveTo']);
    $dayDifference = date_diff($leaveFrom, $leaveTo)->format('%d');
    $yearDifference = date_diff($leaveFrom, $leaveTo)->format('%y');
    $monthDifference = date_diff($leaveFrom, $leaveTo)->format('%m');

    /*These conditions will check the year and month differences too.*/
    if($yearDifference==0)
    {
        if($monthDifference==0)
        {
            if($dayDifference<=4 && $dayDifference>0)
            {
                echo "Eligible";
            }
            else//else for day difference
            {
                echo "Not Eligible";
            }
        }
        else
        {
            echo "Not Eligible";

        }//else for month difference
    }
    else
    {
        echo "Not Eligible";

    }//else for year difference
}

?>
