How to get date range using moment.js

Question

This is my html page

<tr ng-show="option == 'Yearly' || option == 'Date'">
            <td>
                <label>From:</label>
            </td>
            <td>
                <input type="text" ng-model="fromdate" id="from" date-picker date-type="from" month-directive />
                {{fromdate}}
            </td>

            <td>
                <label>To:</label>
            </td>
            <td>
                <input id="todate" type="text" ng-model="todate" date-picker date-type="to" month-directive />
                {{todate}}
            </td>

        </tr>

This is my directive

app.directive('monthDirective', function () {

return {

    restrict:'A',
    link: function (scope, elem) {
        var fromDate, toDate;
        scope.$watch('fromdate', function (newValue, oldValue) {
            fromDate = newValue;
            console.log('fromDate', newValue);
        });
        scope.$watch('todate', function (newValue, oldValue) {
            todate = newValue;
            console.log('todate', newValue);
        });

        var range = moment().range(fromDate, toDate);
        var diff = moment.preciseDiff(fromDate,toDate);
        console.log('Range', range);
        console.log('diff', diff);
    }
}

})

I need to get the range between fromdate and todate using mument.js. Can anyone suggest how to do this in my scenario. Thanks in advance

Answer 1

To get rest of the dates between two dates, you can refer this code-

$scope.dateArr = []; //Array where rest of the dates will be stored

$scope.prevDate = moment().subtract(15, 'days');//15 days back date from today(This is the from date)

$scope.nextDate = moment().add(15, 'days');//Date after 15 days from today (This is the end date)

//extracting date from objects in MM-DD-YYYY format
$scope.prevDate = moment($scope.prevDate._d).format('MM-DD-YYYY');
$scope.nextDate = moment($scope.nextDate._d).format('MM-DD-YYYY');

//creating JS date objects
var start = new Date($scope.prevDate);
var end = new Date($scope.nextDate);

//Logic for getting rest of the dates between two dates("FromDate" to "EndDate")
while(start < end){
   $scope.dateArr.push(moment(start).format('ddd DD-MM'));
   var newDate = start.setDate(start.getDate() + 1);
   start = new Date(newDate);  
}

console.log('Dates:- ');
console.log($scope.dateArr);

This is the console log:-

["Tue 24-05", "Wed 25-05", "Thu 26-05", "Fri 27-05", "Sat 28-05", "Sun 29-05", "Mon 30-05", "Tue 31-05", "Wed 01-06", "Thu 02-06", "Fri 03-06", "Sat 04-06", "Sun 05-06", "Mon 06-06", "Tue 07-06", "Wed 08-06", "Thu 09-06", "Fri 10-06", "Sat 11-06", "Sun 12-06", "Mon 13-06", "Tue 14-06", "Wed 15-06", "Thu 16-06", "Fri 17-06", "Sat 18-06", "Sun 19-06", "Mon 20-06", "Tue 21-06", "Wed 22-06"]

Answer 2

Whilst not as fun as coming up with your own function, the easy answer is to use https://github.com/rotaready/moment-range

Answer 3

const getDaysRange = (date1, date2) => {
  if (date1 && date2) {
    return Math.abs(moment(date2).diff(moment(date1), 'days')) + 1;
  }

  return undefined;
};

Answer 4

If you want to get consecutive days between two dates:

1. Install MomentJS and MomentRange: npm i moment && npm i moment-range
2. Some code

const 
   Moment = require("moment"),
   MomentRange = require("moment-range"), 
   moment = MomentRange.extendMoment(Moment); /*add plugin to moment instance*/ 

let 
   range = moment().range("2018-02-20", "2018-03-01"), /*can handle leap year*/ 
   array = Array.from(range.by("days")); /*days, hours, years, etc.*/ 

array.map(m => {
     console.log(m.format("YYYY-MM-DD")); /*or any format you like*/
});

Answer 5

You can do something like this to get the difference in days:

var fromDate = moment();
var toDate = moment().add(15, 'days');

var range = moment().range(fromDate, toDate);
var diff = range.diff('days');

var array = range.toArray('days');
$.each(array, function(i, e) {
  $(".container").append("<li>" + moment(e).format("DD MM YYYY") + "</li>");
});

console.log('Range', range);
console.log('diff', diff);

EDIT

I added a little example for the toArray function :

Answer 6

I know this is an old/answered question, but since it's at the top of google here is how to achieve a date range with only moment (and without moment-range):

import moment from 'moment'

/**
 * @param {date|moment} start The start date
 * @param {date|moment} end The end date
 * @param {string} type The range type. eg: 'days', 'hours' etc
 */
function getRange(startDate, endDate, type) {
  let fromDate = moment(startDate)
  let toDate = moment(endDate)
  let diff = toDate.diff(fromDate, type)
  let range = []
  for (let i = 0; i < diff; i++) {
    range.push(moment(startDate).add(i, type))
  }
  return range
}

Returns an array of every "type" (month/day/hour etc) between the two, exclusive of the end date

Example:

let range = getRange('2019-01-01', '2019-01-05', 'days')
// moment dates -> [ '2019-01-01', '2019-01-02', '2019-01-03', '2019-01-04' ]
