+             The reason this check is necessary is the reporting end date is selected by the user using a
+             date picker.  The date picker sets the time to 00:00:00.  This means that the date selected for the
+             final report ends up being midnight at the start of the final day.  All generated reports will
+             use midnight at the start of the day after the end date.  This means that when we display the
+             report end date for generated reports we should use the day before the actual end date,
+             except for the final report.
+             Note that for organisationReports, the selected end date is stored as the "periodEnd" for all
+             generated reporting periods which is why using the first one is sufficient.
