  To get the last day of the current month in Javascript, you could use this : 

  var today = new Date();
  var lastOfMonth = new Date(today.getFullYear(),today.getMonth()+1, 0);

  For the first day of the current month, use this : 

  var today = new Date();
  var firstOfMonth = new Date(today.getFullYear(),today.getMonth(), 1);

  Example

  As far as formatting as you have mentioned (using .toString()) you'll have to use something similar to the answers found in this StackOverflow discussion to handle that.

  Thanks Rion,

  The dates work now. I have a datepicker on inout element whihc is not picking up this date..

  <input style="width:6em" data-bind="datepicker: searchBeginDate" />
  And knockout model I have set like this...
   self.searchBeginDate = ko.observable(firstDayofMonth());
   self.searchEndDate = ko.observable(lastDayofMonth());
  In the input box both show today's date only.. Am I doing this correctly?

  I haven't used KnockOut to bind a DatePicker previously. Are each of your your functions that you have within your observable method returning values, ie : 

  function getLastDayOfMonth(){
      var today = new Date();
      return new Date(today.getFullYear(),today.getMonth()+1, 0);
  }

  
  If you are using the jQuery UI DatePicker, based on the information in this Stack Overflow discussion, you should be able to use the minDate and maxDate properties : 

  <input data-bind="datepicker: myDate, datepickerOptions: { minDate: getFirstDayOfMonth(), maxDate:getLastDayOfMonth()  }" />
