there are 2 drop downs one of day and one for month.
The month drop down must have a year formated into the string

if the dep month is changed then dep day is set to 1 and then the ret_mm/ret_dd is set to the date + ReturnDiff
if the dep_day is changed then the return mm/ret_dd is set to the date + ReturnDiff

 if you want to start on the current date then Start Date = 0;
 if you want to start on the current date + 7 days then Start Date = 7;
 if you want the return date to be the same day ReturnDiff = 0
 if you want the return date to be the next day ReturnDiff = 1
