Как вывести записи с определенной датой публикации?

<?php 
$date = getdate();
$todayposts = new WP_Query('showposts=5' . '&year=' .$date["year"] 
.'&monthnum=' .$date["mon"] .'&day=' .$date["mday"]); ?>  
<p>Записи за сегодня (<?php echo date('d.m.Y'); ?>): </p>
<ul>
<?php while($todayposts->have_posts()) : $todayposts->the_post(); ?>    
<li><a href='<?php the_permalink(); ?>'><?php the_title(); ?></a></li>
<?php endwhile; ?> 
</ul>
<?php wp_reset_query(); ?>

<?php $date = getdate(); $todayposts = new WP_Query('showposts=5' . '&year=' .$date["year"] .'&monthnum=' .$date["mon"] .'&day=' .$date["mday"]); ?> <p>Записи за сегодня (<?php echo date('d.m.Y'); ?>): </p> <ul> <?php while($todayposts->have_posts()) : $todayposts->the_post(); ?> <li><a href='<?php the_permalink(); ?>'><?php the_title(); ?></a></li> <?php endwhile; ?> </ul> <?php wp_reset_query(); ?>

<?php 
$date = getdate();
$date["mday"] = $date["mday"] - 1;
$yesterdayposts = new WP_Query('showposts=5' . '&year=' .$date["year"] 
.'&monthnum=' .$date["mon"] .'&day=' .$date["mday"]); ?>  
<p>Записи за вчера (<?php echo date("d.m.Y", time()-(60*60*24));  ?>): </p>
<ul>
<?php while($yesterdayposts->have_posts()) : $yesterdayposts->the_post(); ?>
<li><a href='<?php the_permalink(); ?>'><?php the_title(); ?></a></li>
<?php endwhile; ?> 
</ul>
<?php wp_reset_query(); ?>

<?php $date = getdate(); $date["mday"] = $date["mday"] - 1; $yesterdayposts = new WP_Query('showposts=5' . '&year=' .$date["year"] .'&monthnum=' .$date["mon"] .'&day=' .$date["mday"]); ?> <p>Записи за вчера (<?php echo date("d.m.Y", time()-(60*60*24)); ?>): </p> <ul> <?php while($yesterdayposts->have_posts()) : $yesterdayposts->the_post(); ?> <li><a href='<?php the_permalink(); ?>'><?php the_title(); ?></a></li> <?php endwhile; ?> </ul> <?php wp_reset_query(); ?>
