Hello,

I need help in calculating the median between dates.  For instance if I want to know the median of when the orders were created and when they invoiced.  I've attached a sample Tableau file for analysis.  Here is a sample of my data: 

Order                    Created            Invoiced

6300000012           12/1/2011         3/31/2012

6300000013            1/1/2011          3/2/2012

6301000015             2/1/2011          6/25/2011

6301000017             6/1/2011          8/12/2011

6300089099             4/1/2011          11/3/2012

Thanks for your help.
