In drupal, how do you store/read session variables? Also, how can i access a stored session variable through javascript?
I'm trying to store whether if a user has closed my modal or not so it doesn't pop up for another day.

Accessing a session variable in Drupal is not different from how it is done with plain PHP: with $_SESSION.
As for reading them with JavaScript, it is enough to use code similar to the following one.
// PHP
drupal_add_js(array('myModule' => array('key' => $_SESSION['key'])), 'setting');
// JavaScript
key = Drupal.settings.myModule.key;
