title: Unable to change input date format in angular using input type date
body: <p>I am using angular 10 with bootstrap 4. I want to change input type date format from(dd/mm/yyyy) to DD/MM/YYYY. But its not working.</p>
  <p>Here is my angular code</p>
  <pre><code>&lt;input type=&quot;date&quot; id=&quot;controlKey&quot; class=&quot;form-control&quot; placeholder=&quot;DD / MM / YYYY&quot; /&gt;
  </code></pre>

  <p>But I need to display as below(DD/MM/YYYY). I don't need the placeholder but need date input like bootstrap</p>

  <p>I am not sure where I was doing wrong. Please suggest</p>
  <p>I got code from here <a href="https://stackblitz.com/edit/angular-mc5zsd?file=src%2Fapp%2Fapp.component.ts" rel="nofollow noreferrer">here</a>. It would be helpful if dd/mm/yyyy changes to DD / MM / YYYY</p>
