I'm trying to build a formula.
 
Date range based off Finish date. 
 
Currently I have a date in the Finish date cell and it will populate a text based off the finish date but I really want to do a date range now based off the finish date.  Example below the date range would be 02.01.16 thru 09.30.16.
 
Can someone help me?
 
Current formula/ Example:
=IF(DATEONLY(Finish3)=DATE(2016,9,30), "pre-conversion"
