get all the dates that fall between two dates

Question

i have a problem where the user selects a range of dates. i need to then find out what dates fall between those two selected dates. they're coming in via jquery with something as simple as

$('#from').val()+"-"+$('#to').val();

they're coming from jqueryUI datepicker and they just look like

08/07/2013 - 08/09/2012

but i can't figure out how to step through the dates and determine which days in in between. i need the specific dates, but this becomes really complicated with things like the end of the month and different number of days in each month. in this specific example, i'd need to get

08/07/2013, 08/08/2013, 08/09/2013

Answer 1

You can grab the values from your date pickers using the getDate method, since this will return you a Date object. Then, starting at the start date increment "current" date by 1 day and add it to an array until the current date is the same as the end date.

Note that you'll need to create a new Date() when adding it to the between array, or else you will just be referencing the currentDate object and all your values will be the same.

Working Demo

var start = $("#from").datepicker("getDate"),
    end = $("#to").datepicker("getDate"),
    currentDate = new Date(start.getTime()),
    between = []
;

while (currentDate <= end) {
    between.push(new Date(currentDate));
    currentDate.setDate(currentDate.getDate() + 1);
}
