Javascript - get array of dates between 2 dates

Question

var range = getDates(new Date(), new Date().addDays(7));

I\'d like \"range\" to be an array of date objects, one for each day between the two dates

Answer 1

I'm using simple while loop to calculate the between dates

var start = new Date("01/05/2017");
var end = new Date("06/30/2017");
var newend = end.setDate(end.getDate()+1);
end = new Date(newend);
while(start < end){
   console.log(new Date(start).getTime() / 1000); // unix timestamp format
   console.log(start); // ISO Date format          
   var newDate = start.setDate(start.getDate() + 1);
   start = new Date(newDate);
}

Answer 2

I use moment.js and Twix.js they provide a very great support for date and time manpulation

var itr = moment.twix(new Date('2012-01-15'),new Date('2012-01-20')).iterate("days");
var range=[];
while(itr.hasNext()){
    range.push(itr.next().toDate())
}
console.log(range);

I have this running on http://jsfiddle.net/Lkzg1bxb/

Answer 3

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)

Answer 4

This is how i like to do it

// hours * minutes * seconds * milliseconds
const DAY_IN_MS = 24 * 60 * 60 * 1000

/**
 * Get range of dates 
 * @param {Date} startDate 
 * @param {Number} numOfDays 
 * @returns {array}
 */
const dateRange = (startDate, numOfDays) => {
    const startDateMs = startDate.getTime()

    // get array of days and map it to Date object
    return [...Array(numOfDays).keys()].map(i => new Date(startDateMs + i * DAY_IN_MS))
}

Answer 5

I use this function

function getDatesRange(startDate, stopDate) {
    const ONE_DAY = 24*3600*1000;
    var days= [];
    var currentDate = new Date(startDate);
    while (currentDate <= stopDate) {
        days.push(new Date (currentDate));
        currentDate = currentDate - 1 + 1 + ONE_DAY;
    }
    return days;
}

Answer 6

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 <= 0) {
            return;
        }

        for(var i = 0; i < 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"]
