title: Highlight column based on date in 2 cells
body: <p>I managed to get a column formatted based on the day value that I save in a certain cell.
  How can I additionally check if the day is in the month current month which is represented by the merged cells in the picture below? </p>
  
  <p>In example, currently the formula</p>
  
  <blockquote>
    <p>D$3:AB$3=DAY(TODAY())</p>
  </blockquote>
  
  <p>would highlight 2 columns if the day value is 16/17 but I would like to only highlight the 16th October column in October. </p>
  
  <p>Many thanks for your help</p>
