data = {{{2006, 10, 1}, 10}, {{2006, 10, 15}, 12},
   {{2006, 10, 30}, 15}, {{2006, 11, 20}, 20}};


dlp = DateListPlot[data,
  Epilog -> (Text[
       ToString[{#[[1, 3]], #[[2]]}],
       #, 5/4*Sign[DateDifference[
           {2006, 11, 1}, #[[1]]]*
          {1, 1}]] & /@ data)]


Rotate all strings:


Show[dlp /. str_String :>
   Rotate[str, 90 Degree]]


Rotate just Frame date labels:


Show[dlp /. {v_, str_String} :>
   {v, Rotate[str, 90 Degree]}]
