Here the monitor displays the period-end-date of 2015 and 2016 as 26-09-2015 and 24-09-2016, respectively. Does this mean the formula above lets data be pulled out at any point in time from 27-09-2015 to 24-09-2016? Besides, is my understanding correct that the calendar year 2016 is from 27-09-2015 to 24-09-2016?
