Instead of comparing the dates directly  compare the getTime   value of the date   The getTime   function returns the number of milliseconds since Jan 1  1970 as an integer-- should be trivial to determine if one integer falls between two other integers   Something like  if  check getTime    lt   to getTime    amp  amp  check getTime    gt   from getTime          alert  date contained

I did the same thing that  Diode  the first answer  but i made the condition with a range of dates  i hope this example going to be useful for someone   e g  the same code to example with array of dates    x000D   x000D  var dateFrom    02 06 2013   x000D  var dateTo    02 09 2013   x000D   x000D  var d1   dateFrom split       x000D  var d2   dateTo split       x000D   x000D  var from   new Date d1 2   parseInt d1 1  -1  d1 0        -1 because months are from 0 to 11 x000D  var to     new Date d2 2   parseInt d2 1  -1  d2 0     x000D   x000D   x000D   x000D  var dates    02 06 2013    02 07 2013    02 08 2013    02 09 2013    02 07 2013    02 10 2013    02 011 2013    x000D   x000D  dates forEach element   gt    x000D     let parts   element split       x000D     let date  new Date parts 2   parseInt parts 1   - 1  parts 0    x000D          if  date  gt   from  amp  amp  date  lt  to    x000D             console log  dates in range   date   x000D            x000D     x000D   x000D   x000D

The answer that has 50 votes doesn t check for date in only checks for months  That answer is not correct  The code below works   var dateFrom    01 08 2017   var dateTo    01 10 2017   var dateCheck    05 09 2017    var d1   dateFrom split       var d2   dateTo split       var c   dateCheck split        var from   new Date d1       -1 because months are from 0 to 11 var to     new Date d2   var check   new Date c    alert check  gt  from  amp  amp  check  lt  to     This is the code posted in another answer and I have changed the dates and that s how I noticed it doesn t work  var dateFrom    02 05 2013   var dateTo    02 09 2013   var dateCheck    07 07 2013    var d1   dateFrom split       var d2   dateTo split       var c   dateCheck split        var from   new Date d1 2   parseInt d1 1  -1  d1 0        -1 because months are from 0 to 11 var to     new Date d2 2   parseInt d2 1  -1  d2 0    var check   new Date c 2   parseInt c 1  -1  c 0      alert check  gt  from  amp  amp  check  lt  to

Simplified way of doing this based on the accepted answer   In my case I needed to check if current date  Today  is pithing the range of two other dates so used newDate   instead of hardcoded values but you can get the point how you can use hardcoded dates    var currentDate   new Date   toJSON   slice 0 10   var from   new Date  2020 01 01    var to     new Date  2020 01 31    var check   new Date currentDate    console log check  gt  from  amp  amp  check  lt  to

Date parse supports the format  mm dd yyyy not dd mm yyyy  For the latter  either use a library like moment js or do something as shown below  var dateFrom    02 05 2013   var dateTo    02 09 2013   var dateCheck    02 07 2013    var d1   dateFrom split       var d2   dateTo split       var c   dateCheck split        var from   new Date d1 2   parseInt d1 1  -1  d1 0        -1 because months are from 0 to 11 var to     new Date d2 2   parseInt d2 1  -1  d2 0    var check   new Date c 2   parseInt c 1  -1  c 0     console log check  gt  from  amp  amp  check  lt  to

Suppose for example your date is coming like this  amp  you need to install momentjs for advance date features  let cmpDate   Thu Aug 27 2020 00 00 00 GMT 0530  India Standard Time       let format    quot MM DD YYYY quot       let startDate  any   moment   format format       let endDate  any   moment   add 30   quot days quot   format format       let compareDate  any   moment cmpDate  format format       var startDate1   startDate split  quot   quot        var startDate2   endDate split  quot   quot        var compareDate1   compareDate split  quot   quot         var fromDate   new Date startDate1 2   parseInt startDate1 1   - 1  startDate1 0        var toDate   new Date startDate2 2   parseInt startDate2 1   - 1  startDate2 0        var checkDate   new Date compareDate1 2   parseInt compareDate1 1   - 1  compareDate1 0         if  checkDate  gt  fromDate  amp  amp  checkDate  lt  toDate              condition works between current date to next 30 days
