[Plugin: Events Manager] Get the date of next upcoming event in other format

I want to get the date of the next upcoming event with a shortcode, for now I used:

<?php em_events('limit=1')?>

But it shows up in the default format taken from the settings page. Which is like:

Date       | Event
-------------------------
05-08-2011 | Event name 1

Which I created with a table.

All I want is just the date, not the other info like the titles I gave in the settings page. I think I have to do something with the ‘format’ attribute…but can’t figure out how.
