gistfile1.aw

global $post;
	
	$args = array(
		'post__not_in'	=> array( $post->ID ),
		'posts_per_page'=> -1,
		'day'			=> get_the_time( 'd', $post->ID ),
		'month'			=> get_the_time( 'm', $post->ID ),
		'year'			=> get_the_time( 'Y', $post->ID ),
	);
	$the_query = new WP_Query( $args );

	if ( $the_query->have_posts() ) :
		
		// The Loop
		while ( $the_query->have_posts() ) : $the_query->the_post();
					
		endwhile;		
		
	endif;
	
	// Reset Post Data
	wp_reset_postdata();
	
	// Reset Query
	wp_reset_query();
