title: SUMIF and DATEDIF by row
body: <p>I have a row of dates, with one date per column.  Dates are in order from oldest to newest.  I am trying to count only those where the difference is 14 days or greater.  I need it to count by row</p>
  
  <p>Date A   |  Date B  |   Date C  |  Date D   |  2</p>
  
  <p>So Date B - Date A = 13| Date C - Date B = 29| Date D - Date C = 15| 2</p>
  
  <p>The formula should return 2, since the first was less than 14 days. 
  I've spend hours on various forums with no luck.  I never post since I am usually able to figure my problems out by reading other's kind posts &amp; suggestion.  I appreciate whatever help comes my way.</p>
