Is START being returned as a string, or as a DateTime from your query? If
it's being returned as a string, you need:

  <dtml-call "REQUEST.set('startdate', _.DateTime(START))">

aMonth() is a method, not an attribute. You need to _call_ it, i.e.:

  <dtml-call "REQUEST.set('month', _.DateTime(startdate).aMonth())">

or, if startdate is already a DateTime:

  <dtml-call "REQUEST.set('month', startdate.aMonth())">

Another way of doing this, however, is something like the following:

  <dtml-call "REQUEST.set('mydate', _.DateTime('2000/12/31'))">
  <dtml-var mydate fmt=dd>-<dtml-var mydate fmt=aMonth>-<dtml-var mydate
fmt=year>

Voila.

The above does not seem too difficult to me. You made a few simple
mistakes, that's all.
