This will also checks in leap year  This is pure regex  so it s faster than any lib  also faster than moment js   But if you gonna use a lot of dates in ur code  I do recommend to use moment js  var dateRegex         d       31       0  2469  11      30 29     0 2  29    0 2          1 6-9   2-9  d     0 48   2468  048   13579  26         16  2468  048   3579  26  00       x20        2 0-8  1 d 0  1-9     -        1 012  0  1-9   1   1 6-9   2-9  d   d d       x20 d  x20        0  1-9  1 012     0-5  d  0 2   x20 AP M     01  d 2 0-3     0-5  d  1 2        console log dateRegex test  21 01 1986         http   regexper com

If you use the moment js library it can easily be done like this -  jQuery validator addMethod  validDate   function value  element            return this optional element     moment value  DD MM YYYY   isValid            Please enter a valid date in the format DD MM YYYY

I encountered a similar problem in my project  After struggling a lot  I found this solution   if    datepicker parseDate  dd mm yy   17 06 2015    gt    datepicker parseDate  dd mm yy   20 06 2015           do something   You DO NOT NEED plugins like jQuery Validate or Moment js for this issue  Hope this solution helps

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   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
