active record for [where date >= now()]

[eluser]RaZoR LeGaCy[/eluser]
How can I set and active record for where date >= now()

I tried including helper date
I tried this

Code:

$this->db->select('title, dvd, date');
$this->db->from('hh_events');
$this->db->limit ('7');
$this->db->like ("(dvd LIKE '1' OR theater LIKE '1')");

$this->db->where ("(date >= now())");

$data['events'] = $this->db->get();

Everything works without the date part but I need the date part for my events system
