I have this html:

1.     <input class="smalldatepicker" type="date" id="datepickerFrom" value="2016-09-04">
       </input>
       <label class="cccsfont"> to </label>
       <input type="date" class="smalldatepicker" id="datepickerTo" value="2016-09-10">
       </input>

Which sets "datepickerTo" to the last Saturday (this is based on today's date of Thursday, 9/15) and "datepickerFrom" to the Sunday before that.

This is manually added, though; I want to do it programmatically, in jQuery, something like:

1.     var lastSat = getLastSaturday(); // return in form "YYYY-MM-DD" 
       var sundayBeforeLastSat = getSundayBeforeLast(lastSat); // " "
       
       $("#datepickerTo").val(lastSat);
       $("#datepickerFrom").val(sundayBeforeLastSat);

I think this should work, but I don't know what to put in the functions:

1.     function getLastSaturday() {
            return ???;
       }
       
       function sundayBeforeLastSat(lastSat) {
            return ???;
       }
