Problem: I have a Form that includes a custom date field. That date field is used to save a birthdate. I would like to create a conditional group that displays some content in the Form if the birthdate is less than 18 years ago.

Solution: Toolset's date fields store Unix timestamps that represent dates. These are simple numbers. If you want to compare that date to a date in the past, you need to create a Unix timestamp for that date in the past. Then you can compare those two timestamp values like comparing any other numbers. The following custom shortcode can be used to generate a Unix timestamp from the text string "18 years ago":

add_shortcode( 'tssupp-strtotime', 'tssupp_strtotime');
function tssupp_strtotime($atts = [])
{
  $atts = shortcode_atts([
    'string' => '',
  ], $atts);
  $time = strtotime($atts['string']);
  return $time;
}

Register tssupp-strtotime in Toolset > Settings > Front-end Content > Functions Inside Conditional Evaluations. Then in the basic Form builder you can implement the shortcode in a conditional like so:

( '$(cliente-data-de-nascimento)' gt '[tssupp-strtotime string="18 years ago"]' )

Or in expert mode:

[cred_show_group if="( '$(cliente-data-de-nascimento)' gt '[tssupp-strtotime string="18 years ago"]' )" mode="fade-slide"]
Age is less than 18
[/cred_show_group]
