title: Google Sheets Query where Date is Greater than Another Date + 15 Days
body: <p>I have a Query formula in Google Sheets where I'm trying to set a condition that shows rows where Col1 > (Col2 +15 days).  I'm not sure how to do the math on the +15 days in the Query formula. </p>
  
  <p>I tried the following code:</p>
  
  <pre><code>=Query(A:B,"Select * where Col1&gt;Col2+15")
  </code></pre>
  
  <p>I want it to show me where Column 1 is greater than the Col2 date + 15 days</p>
