Pandas select discontinuous dataframe date slices?

I have a pandas DF with datetime index: this select works fine ``` threeyrs=actdf['01/01/2010':'12/31/2012'] ``` but I'd like to get something like this (to exclude 2010): ``` threeyrs=actdf['01/01/2009':'12/01/2009','01/01/2011':'12/01/2012'] ``` which gives me "unhashable type" and this gives me a string ``` threeyrs=actdf['01/01/2009':'12/31/2009'],actdf['01/01/2011':'12/31/2012'] ``` Is there a convenient way? dataFrame looks like ``` Units date 2000-05-01 3041 2000-06-01 3079 2000-07-01 2455 2000-08-01 2671 2000-09-01 2220 ```
