Compare the two dates:
Date today = new Date();
Date myDate = new Date(today.getYear(),today.getMonth()-1,today.getDay());
System.out.println("My Date is"+myDate);
System.out.println("Today Date is"+today);
if (today.compareTo(myDate)<0)
System.out.println("Today Date is Lesser than my Date");
else if (today.compareTo(myDate)>0)
System.out.println("Today Date is Greater than my date");
else
System.out.println("Both Dates are equal");
