Random order in async node.js

I now use this code (part of my code):

async.forEachOfSeries(dates, function(mydate, m, eachDone) { 
        eachDateParse(Name,Place,Strategy, eachDone)
}, function(err) {
    if (err) throw err;
    console.log("All Done!");
    callback(); }
);

async.forEachOfSeries does loop over dates in order, but is there any async function that can randomise the order of the loop over dates?

Best Regards

This is an example for my comment as requested

var dates = ['20110101', '20120101', '20130101', '20140101', '20150101'];

async.sortBy(dates, function(item, callback) {
    callback(null, Math.random());
}, function(err, result) {
    console.log('Sorting is finished.');
    async.each(result, function(date, callback) {
        console.log('Parsing date: ' + date);
        callback();
    }, function(error, res) {
        console.log('All dates are parsed now.');
    });
});

although I'm not quite sure if nesting async functions is a good idea it seems to be working.
