Just came across this question  the easiest way to do this is using moment   You need to install moment and moment-range first   const Moment   require  moment    const MomentRange   require  moment-range    const moment   MomentRange extendMoment Moment    const start   moment   const end   moment   add 2   months   const range   moment range start  end  const arrayOfDates   Array from range by  days    console log arrayOfDates

I was recently working with moment js  following did the trick    function getDateRange startDate  endDate  dateFormat            var dates                   end   moment endDate               diff   endDate diff startDate   days             if  startDate isValid       endDate isValid      diff  lt   0                return                     for var i   0  i  lt  diff  i                  dates push end subtract 1  d   format dateFormat                       return dates             console log getDateRange startDate  endDate  dateFormat      Result would be     09 03 2015    10 03 2015    11 03 2015    12 03 2015    13 03 2015    14 03 2015    15 03 2015    16 03 2015    17 03 2015    18 03 2015

I had trouble using the answers above  The date ranges were missing single days due to timezone shift caused by the local day light saving time  DST   I implemented a version using UTC dates that fixes that problem   x000D   x000D  function dateRange startDate  endDate  steps   1      const dateArray         let currentDate   new Date startDate      while  currentDate  lt   new Date endDate         dateArray push new Date currentDate           Use UTC date to prevent problems with time zones and DST     currentDate setUTCDate currentDate getUTCDate     steps          return dateArray     const dates   dateRange  2020-09-27    2020-10-28    console log dates   x000D   x000D   x000D   Note  Whether a certain timezone or DST is applied  depends entirely on your locale  Overriding this is generally not a good idea  Using UTC dates mitigates most of the time related problems  Bonus  You can set the time interval for which you want to create timestamps with the optional steps parameter  If you want weekly timetamps set steps to 7

You can do it easily using momentJS Add moment to your dependencies npm i moment  Then import that in your file var moment   require  quot moment quot     Then use the following code to get the list of all dates between two dates let dates       let currDate   moment utc new Date  quot 06 30 2019 quot    startOf  quot day quot    let lastDate   moment utc new Date  quot 07 30 2019 quot    startOf  quot day quot     do    dates push currDate clone   toDate       while  currDate add 1   quot days quot   diff lastDate   lt  0   dates push currDate clone   toDate      console log dates

I have been using  Mohammed Safeer solution for a while and I made a few improvements  Using formated dates is a bad practice while working in your controllers  moment   format   should be used only for display purposes in views  Also remember that moment   clone   ensures separation from input parameters  meaning that the input dates are not altered  I strongly encourage you to use moment js when working with dates   Usage    Provide moment js dates as values for startDate  endDate parameters interval parameter is optional and defaults to  days   Use intervals suported by  add   method  moment js   More details here total parameter is useful when specifying intervals in minutes  It defaults to 1    Invoke   var startDate   moment        endDate   moment   add 1   days     getDatesRangeArray startDate  endDate   minutes   30     Function   var getDatesRangeArray   function  startDate  endDate  interval  total        var config                 interval  interval     days               total  total    1                    dateArray               currentDate   startDate clone         while  currentDate  lt  endDate            dateArray push currentDate           currentDate   currentDate clone   add config total  config interval              return dateArray

Here s a one liner that doesn t require any libraries in-case you don t want to create another function   Just replace startDate  in two places  and endDate  which are js date objects  with your variables or date values   Of course you could wrap it in a function if you prefer  Array Math floor  endDate - startDate    86400000    1  fill   map     idx    gt   new Date startDate getTime     idx   86400000

If you are using moment then you can use their  official plugin  for ranges moment-range and then this becomes trivial   moment-range node example   const Moment   require  moment    const MomentRange   require  moment-range    const moment   MomentRange extendMoment Moment    const start   new Date  11 30 2018    end   new Date  09 30 2019   const range   moment range moment start   moment end     console log Array from range by  day       moment-range browser example    x000D   x000D  window  moment-range   extendMoment moment   x000D   x000D  const start   new Date  11 30 2018    end   new Date  09 30 2019   x000D  const range   moment range moment start   moment end    x000D   x000D  console log Array from range by  day     x000D   lt script src  https   cdnjs cloudflare com ajax libs moment js 2 22 2 moment min js  gt  lt  script gt  x000D   lt script src  https   cdnjs cloudflare com ajax libs moment-range 4 0 1 moment-range js  gt  lt  script gt  x000D   x000D   x000D    date fns example   If you are using date-fns then eachDay is your friend and you get by far the shortest and most concise answer    x000D   x000D  console log dateFns eachDay  x000D    new Date 2018  11  30   x000D    new Date 2019  30  09  x000D     x000D   lt script src  https   cdnjs cloudflare com ajax libs date-fns 1 29 0 date fns min js  gt  lt  script gt  x000D   x000D   x000D

Note  I m aware this is slightly different than the requested solution  but I think many will find it useful    If you want to find each  x  intervals  days  months  years  etc     between two dates  moment js and the moment-range extension packages enable this functionality   For example  to find each 30th day between two dates   window  moment-range   extendMoment moment    var dateString    2018-05-12 17 32 34 874-08   var start    new Date dateString   var end      new Date    var range1   moment range start  end   var arrayOfIntervalDates   Array from range1 by  day     step  30       arrayOfIntervalDates map function intervalDate     console log intervalDate format  YY-M-DD
