Hi,
In JavaScript when the Date is created with new Date(2011, 1, 4), the actual date is “Feb 4, 2011”, because the months start from zero. For that in the labels the month is February.
http://www.w3schools.com/js/js_obj_date.aspYou can change to:
minimum: new Date("Feb 4,2011"),
maximum: new Date("Feb 18,2011"),
and you can observe the behavior.
Thanks for the good words about our product. We are actively working on it. Actually we are going to release a new version in a few days. You can read about the new features here:
