Removing time – showing just date

You’d just need to mark which days are unavailable yourself through the plugin’s settings page. Those days will appear as unavailable at the front-end. You’d probably then want to remove the “Some slots taken, see below” line from the legend. If you’re comfortable editing PHP, change line 304 in diary-and-availability-calendar.php from:

$legend .= '
  <div id="daac-legend">
    <div class="legend-item">
      <span class="available">_</span>Available all day
    </div>
    <div class="legend-item">
      <span class="bookings">_</span>Some slots taken, see below
    </div>
    <div class="legend-item">
      <span class="unavailable">_</span>Unavailable
    </div>
  </div>
';

to:

$legend .= '
  <div id="daac-legend">
    <div class="legend-item">
      <span class="available">_</span>Available all day
    </div>
    <!--<div class="legend-item">
      <span class="bookings">_</span>Some slots taken, see below
    </div>-->
    <div class="legend-item">
      <span class="unavailable">_</span>Unavailable
    </div>
  </div>
';

Hope that helps
