Filtering events for current week

I want to display events for the current week. This code (with the dates hardcoded) displays the events.

                perch_events_custom(array(
                    'filter'=>'eventDateTime',
                    'match'=>'eqbetween',
                    'value' => '2015-08-30, 2015-09-06',
                    'sort'=>'eventDateTime',
                    'sort-order'=>'desc',
                    'template'=>'listing/banner-listing.html'
                ));

<perch:events id="eventDateTime" type="date" format="oW" /> displays current week number (201536 for this week). Is there a way to use oW to filter dates. I've tried

    'match'=>'eq',
    'value' => date('oW'),

but that doesn't work. John
