[Plugin: Woocommerce] Drop Price Plugin Timeframe End Date

I got this code for the sale start & end date, So it shows on a product page:

add_action( 'woocommerce_single_product_summary', 'woocommerce_output_sale_end_date', 10 );
function woocommerce_output_sale_end_date() {
$sale_end_date = get_post_meta( get_the_ID(), '_sale_price_dates_to', true );
if ( ! empty( $sale_end_date ) )
echo '<span id="sale-price-to-date">' . __( 'Sale End Date: ', 'woocommerce' ) . date( 'Y-m-d', $sale_end_date ) . '</span>';
}

Somehow I need to ad this code, so it picks up the drop price timeframe from the drop price plugin for woocommerce instead of the sale end date:

$drop_price_dates_from 	= ( $date = get_post_meta( $post->ID, '_drop_price_dates_from', true ) ) ?  $date  : '';
$drop_price_dates_to 	= ( $date = get_post_meta( $post->ID, '_drop_price_dates_to', true ) ) ?  $date  : '';

I also got this code to show the drop price timer on the homepage, but I want it to show the drop price timeframe. Any solution?

add_action( 'woocommerce_after_shop_loop_item_title', 'wpgenie_show_counter_on_loop',50 );
function wpgenie_show_counter_on_loop(){
	global $product;
	if(!isset ($product))
		return;
	if (isset($product->drop_price_counter) && ($product->drop_price_counter == 'yes') && isset($product->drop_price_next_drop) && $product->drop_price_next_drop){
		echo '<div class="drop-price-counter">';
		echo '<div class="drop-price-time" id="countdown">
				<div class="drop-price-countdown" data-time="'.$product->drop_price_next_drop.'" data-productid="'.$product->id.'" ></div>
			</div>';
		echo "</div>";
	}
}
