Question

By setting

minDate: "-1M", 
maxDate: "+1M",

I am getting minDate as 24/Aug/2012 and maxDate as 24/oct/2012.
I want minDate as Start date of previous month i.e 01/Aug/2012 and maxDate as end date of next month 31/oct/2012.

How should i configure date picker to get it?

You need to calculate the dates yourself:

var minDate = new Date();
minDate.setMonth(minDate.getMonth()-1, 1);
var maxDate = new Date();
maxDate.setMonth(maxDate.getMonth()+2, 0);
$("#datepicker").datepicker( {
    ...
    minDate: minDate,
    maxDate: maxDate,
    ...
});
