The Date Range is used to define what the Current Period is. The Date Range will determine what guest registrations will be listed in the 'Current' pop-down list and what guest registrations will be listed in 'Current' reports.

The Date Range is typically set to the Current Week however it can be set for any duration to cause the various lists and reports to respond accordingly.

Also, the 'From Date' in the Date Range will define the Current Year. The Current Year is the year that is used in all respective lists and reports that include a single year of reporting.

The Date Range is set by clicking on the 'Set Date Range' button that appears on date sensitive screens...

This will bring up a dialog box to set the Date Range...  

Note that you can sort the information on this screen by right-Clicking on the column that you want to sort and then choosing 'Ascending' or 'Descending'.
