How to select a day and not a month when choosing a date?

Question

an error with the date selection. When I select a day in the calendar, the month is recorded and I cannot select more than 12. For example, I select January 12, but December 1 comes on the date. Help me please. I think the whole problem is that I create a date and I need to make a date instance

function nextmonths() {
  var start_multi = new Date(document.getElementById("date__start").value);
  var next_date_unformatted = start_multi;
  var next_date_formatted;

  var next_date;
  next_date = new Date(next_date_unformatted);
  console.log(next_date)
  next_date_formatted = next_date.toLocaleDateString()
  document.getElementById("date__end").value = next_date_formatted;
  dateSelected.innerHTML = 'С' + '  ' + start_multi + ' ' + 'по' + ' ' + next_date_formatted;
}

Code–only answers aren't that helpful. A good answer should explain why the OP has their issue and how your code fixes it. You should also provide some example input and output, and even better post as a runnable snippet to show the code working. – RobG Mar 15 '23 at 08:14
