The 4th and the 11th are Mondays...??
If you mean the 2nd and 3rd of October I'm a possibly...
If you mean the 9th and 10th of October I'm a no.
If it is actually the mondays - No.
If in fact you have looked at 4th and 5th of SEPTEMBER I'm a possibly, and the 11th and 12th of September - possibly!
Clarification on the dates perhaps?
