I would like to change the WordPress page’s publish date based on post id programmatically

You will need to use wp_update_post function to update the publish date info of a WordPress Page

$page = array();
$page['ID'] = 1; // the page ID you want to update
$page['post_date'] = $your_date; // uses 'Y-m-d H:i:s' format
wp_update_post($page);
