Moment.js datepicker won't accept my dates - reactjs

Question

I'm currently working on a project using React.js.
I’m using material-ui datepicker and I'm blocking all dates except the 14 upcoming dates. What I want is that every Thursday I get 14 new dates in my datepicker.
I'm supposed to add my beginningOfWeek and endOfWeek into my maxDate and minDate, but it's currently not working and I can't figure out how to get it right.
It types out the correct answer in the log but when I press the datepicker I'm getting an error and the debugger says:
TypeError: d2.getFullYear is not a function at monthDiff
What am I doing wrong?
I've used this example for my own code. How to get the date ranges of a given week number in JS
This is my code:
var moment = require('moment');
const w = moment().weekday();
const daysToSubtract = (w + 3)%7;
const beginningOfWeek = moment(new Date()));
const endOfWeek = moment(new Date()).add(-daysToSubtract, 'days');
console.log(beginningOfWeek.format('MM/DD/YYYY h:mm a'),
endOfWeek.format('MM/DD/YYYY h:mm a'))
<div className="center-container">
<DatePicker hintText={newdate} mode="landscape" maxDate={endOfWeek}
minDate={beginningOfWeek}/>
</div>

Answer 1

I solved it by doing this. I changed my maxDate into maxDate = {new Date(endOfWeek)}/>
const moment = require('moment');
const w = moment().weekday();
const daysToSubtract = ((w + 3 + Math.floor(hours/16)))%7 ;
const beginningOfWeek = moment().add(-daysToSubtract, 'days');
const endOfWeek = moment().add(14-daysToSubtract, 'days');
console.log(beginningOfWeek);
console.log(endOfWeek);
<div className="center-container">
<DatePicker hintText={newdate} mode="landscape" minDate={new
Date()} maxDate = {new Date(endOfWeek)}/>
</div>
