How to make inactive choice years in the calendar?

Hi all. Has anyone worked with this calendar All in it arranges, but there is one drawback. You cannot restrict the selection range of years in the pop-up tooltip. Maybe someone knows the solution to this problem? Or advise, pliz, another calendar with that option (without jquery, this is important).

In General solved a problem, reached into the source code and corrected.
