Displaying relative dates in a Views Exposed Filter I have a view displaying a collection of events with a date field the user can set the range of. For a default value, I have +0 days to +90 days, so the user can see all events during the next 90 days. The image below shows all my setting information for the date filter.



Currently, the user sees relative dates when they load the page, as the next image shows:


But I would like this to show dates to the user, instead of these relative values when they load the page. In the picture above, if the date they were viewing the page was 1/11/17, I would like the user to see 1/11/17 to 4/11/17 instead of +0 days to +90 days. What would be the simplest way to make this conversion in Drupal 8?
Edited - You can apply datepicker to the field, as Jquery Ui date picker is available in Drupal8. For reference see to this

Or,

you can programmatically alter the view query in hook_views_query_alter()

function module_name_views_query_alter(ViewExecutable $view, QueryPluginBase $query) {
 // Query alter to provide dynamic date ranges.
 if ($view-&gt;id() == 'VIEW ID' &amp;&amp; $view-&gt;current_display == 'page_1')
 {
    foreach ($query-&gt;where[0]['conditions'] as $key) {
      if (array_key_exists(':node__field_start_date_time.field_start_date_time_value[]', $key['value'])) {
        // do anything you want...
        ...
        ...
      }
    }
 }
