This calendar widget can be used by either including dhtml-suite-for-applications.js or by including only dhtmlSuite-common.js and by using the DHTMLSuite.include() function, i.e. DHTMLSuite.include("calendar")
This is one of the Free calendar scripts from DHTMLGoodies.com.
This is done by adding invalid date ranges:
myCalendarModel5.addInvalidDateRange(false,{year: 2003,month:12,day:31}); myCalendarModel5.addInvalidDateRange({year: 2005,month:1,day:1},false);
