Javascript – get array of dates between 2 dates

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.

The trick is that it should handle month and year boundaries as well.


function (startDate, endDate, addFn, interval) {

 addFn = addFn || Date.prototype.addDays;
 interval = interval || 1;

 var retVal = [];
 var current = new Date(startDate);

 while (current <= endDate) {
  retVal.push(new Date(current));
  current =, interval);

 return retVal;
