I think doing anything with dates is horrible in JavaScript compared to PHP but here is a function to make adding x days to a date a little easier: function dateAdd(theDate, numDays) {   /** * Date must be YYYY-MM-DD or DD-MM-YYYY – other formats will not work */   numDays = parseInt(numDays);   if(theDate.indexOf("/") […]

If you find yourself wanting to style each tab individually, or attaching a certain JavaScript attributes to a particular tab this this code is very useful.
