Really Complex Date Calculation

Hi,

Can someone please guide me how to extract this particular data. It is quite complex, the raw data is not in a good shape and I am not sure if it is even possible. For simplification, I am copying a sample of only 3 columns from my table.

ID FromDate ToDate
01 06/09/2006 06/09/2006
02 06/09/2006 06/12/2006
03 06/09/2006 06/12/2006
04 06/09/2006 06/12/2006
05 06/09/2006 06/12/2006
06 06/09/2006 06/12/2006
07 06/10/2006 06/10/2006
08 06/12/2006 06/12/2006
09 08/30/2006 09/05/2006
10 08/30/2006 09/05/2006
11 08/30/2006 09/05/2006
12 09/13/2006 09/17/2006
13 09/13/2006 09/26/2006
14 09/13/2006 09/26/2006
15 10/05/2006 10/10/2006
16 10/05/2006 10/10/2006
17 10/10/2006 10/15/2006
18 10/11/2006 10/11/2006
19 10/16/2006 10/16/2006
20 10/20/2006 10/22/2006
21 10/23/2006 10/25/2006

From and to date represent a duration of an event, but in some instances the data has multiple lines but they are all to be considered one event. For example all the from dates (row 1 to 8) in Oct 06 are covered by ID/row 05 because 6/9/06 to 6/12/06 is one event, all other rows of June 06 data are just redundant and not needed in the resultset. There isn't a unique event name either so comparing and picking row 05 just based on the above data is an issue.
Another problem is for example the dates in October (10/5 - 10-16) all represent 1 event but the date span is spread all over. Multiple events are also possible in one month, so gettign MIN and MAX based on the month will not work.

The desired result set need to have duration of each unique event for example (1 in June, 1 in August, 1 in Sept, and 1 in Oct) and also need to have the number of events after that date and the calculated from and to date of that event:
