This code displays the total number of entries at the beginning of a day on a Calendar View.

add_action( 'frm_before_day_content', 'ff_day_count' );
function ff_day_count( $pass_atts ) {
	if ( $pass_atts['view']->ID === 608 ) {
		echo "<h4> Total: " . $pass_atts['day_count'] . "</h4>";
	}
}

Change:

• 608 to your View ID
• <h4></h4> to any HTML element you'd like
• Total: to any content you'd like

You can also rewrite the echo statement as you'd like.
