event creation in full calendar throws me an end date (end) with one more day of the account and unnecessary time data

In this picture I show what is going on, I am using fullcalendar

in this picture I show the selected days

in this sample the first error, the calendar before saving the date is already bringing me a bad data, if I think any date is added a day more, if I create an event for today, it shows me that the end date is tomorrow.

I do not fully understand why it happens ...

the following code is how I have built the calendar

$(document).ready(function() {
var initialLocaleCode = 'es'; 

       var date = new Date();
       var yyyy = date.getFullYear().toString();
       var mm = (date.getMonth()+1).toString().length == 1 ? "0"+(date.getMonth()+1).toString() : (date.getMonth()+1).toString();
       var dd  = (date.getDate()).toString().length == 1 ? "0"+(date.getDate()).toString() : (date.getDate()).toString();

      select: function(start, end) {
         var check = moment(start).format('YYYY-MM-DD');
         var today = moment(new Date()).format('YYYY-MM-DD');

      if (check >= today) {
