Angular & Javascript: Date is 7 days old and is monday

I have a angular app which is connected to a rest api. To reduce the requests i save all data in the localstorage. 

.factory('$localstorage', ['$window', function($window) {
  return {
    set: function(key, value) {
        var object = {value: value, timestamp: new Date().getTime()}
        $window.localStorage[key] = JSON.stringify(valueWithTimestamp);
    },
    setObject: function(key, value) {
        var object = {value: value, timestamp: new Date().getTime()}
        $window.localStorage[key] = JSON.stringify(object);
    },
  }
}]);

There will be new data every monday, so all i want to do is to check if the localstorage is 7 days old and if the current weekday is monday.

Then the data should refresh. Do you have any idea how to solve this simple problem?

Ok, here is my function. Should work now :)

function getNextDayOfWeek(date, dayOfWeek) {
        // Code to check that date and dayOfWeek are valid left as an exercise ;)
        var resultDate = new Date(date.getTime());
        if (date.getDay() === 1 && dayOfWeek === 1) {
          resultDate.setDate(date.getDate() + 7)
        }
        else {
          resultDate.setDate(date.getDate() + (7 + dayOfWeek - date.getDay()) % 7);
        }
        return resultDate;
    }
