View event from a specific date range.

I would like to create a list of dates in a 15 day span.

Current the date range functions it represented as so.

$current_date = date(‘j M Y’);
$end_date = date(‘j M Y’, strtotime(’30 days’));

I have tried a few ways to do this, like so. With no luck.

$current_date = date(‘1-15-2013’);
$end_date = date(‘1-31-2013’);

Please help, am sure its easy fix. thanks.
