Can someone explain where session variables are held?
I have added some session variables in header.php in the controller, for example:
$this->session->data['day']=date("d",strtotime($row['startdate']));
This works when loading the site, and when I click on a product, all the variables are gone, except for the [language], [currency] and [cart] which are set by Opencart.
I guess there is another file or controller file where I set the variables, or where [language], [currency] and [cart] are set but I cannot find it.
Thanks in advance.

Session values are not set in a file. If you want to set a session variable, use
$this->session->data['variable_name_here'] = 'data value here';
and to retrieve the value you just access
$this->session->data['variable_name_here']
For example, to echo it use
echo $this->session->data['variable_name_here'];
