There's no built-in way to make date range calculations like this in Toolset, but I do have a custom shortcode that might help.
- Create a custom field on your post type. Make it a date field, and call it "deadline"
- Add the following code to your functions.php file:

add_shortcode( 'format_date_difference', 'format_date_difference_func');
function format_date_difference_func($atts = [])
{
  $atts = shortcode_atts([
    'start' => '',
    'end' => '',
    'format' => '%y years, %m months, %d days',
  ], $atts);
  $datetime1 = new DateTime($atts['start']);
  $datetime2 = new DateTime($atts['end']);
  $interval = $datetime1->diff($datetime2);
  return $interval->format($atts['format']);
}

-Then add the shortcode to your Content Template:

[format_date_difference start='[types field="deadline" format="Y-m-d"][/types]' end='' format='%a days']
