Display most popular in the past two days

Hi I'm using this code below to display the most popular post on my wordpress site. It works great! I was wondering if there was anyway to show the most popular post of the current day?

This in my functions.php

function getPostViews($postID){
$count_key = 'post_views_count';
$count = get_post_meta($postID, $count_key, true);
if($count==''){
    delete_post_meta($postID, $count_key);
    add_post_meta($postID, $count_key, '0');
    return "0 View";
}
return $count.' Views';
}
function setPostViews($postID) {
$count_key = 'post_views_count';
$count = get_post_meta($postID, $count_key, true);
if($count==''){
    $count = 0;
    delete_post_meta($postID, $count_key);
    add_post_meta($postID, $count_key, '0');
}
else{
    $count++;
    update_post_meta($postID, $count_key, $count);
}
}

and this in my theme file

?php
global $post;
$args = array( 'numberposts' = 5, 'offset'= 1, 'category' = 1 );
$myposts = get_posts( $args );
foreach( $myposts as $post ) :  setup_postdata($post); ?
lia href="?php the_permalink(); ?"?php the_title(); ?/a/li
li?php setPostViews(get_the_ID()); echo getPostViews(get_the_ID());; ?/li
?php endforeach; ?
