How to exclude date of my post on specific category and post?

Guys, have one more question. I am asking, because the structure of your theme is too difficult for me. Usually WP themes have some different structure, anyway I like this theme ??
Question: how can I hide date of post on specific category and specific post?

If I’d like to make it on some other theme, I would use this code

<?php if (!is_category(22) and !in_category(22)) { ?>
<div class="entry-meta">
    <?php limelight_posted_on(); ?>
</div><!-- .entry-meta -->
<?php } ?>

But how to make it on your theme? ??
