sorting events at menu entry "show categories"

Ahoi,

I have got a problem concerning my events' order. Of course I have created a menu item "show categories" (I only have one) and it works fine. But its order is ascending - so I like to have it descending.

now:

01.01.2013
Event 1
02.01.2013
Event 2
...
01.01.2015
Event n


better:

01.01.2015
Event n
...
01.01.2013
Event 1
02.01.2013
Event 2


As you can see, the order shall be reversed. I know it's said to be a way as easy as smashing your head to your desk but obviously I was not able to find it. I am slowly going crazy.

thanks in advance
