Question

How to change the post date to a randomly generated date?

Answer

This is fairly straightforward. What I did was to create a plugin that upon activation get all the posts, loops through them, generates a random date, and updates the post with that date.

<?php
/**
 * Plugin Name: WPSE 259750 Random Dates
 * Description: On activation, change the dates of all posts to random dates
 */

//* We want to do this only once, so add hook to plugin activation
register_activation_hook( __FILE__ , 'wpse_259750_activation' );
function wpse_259750_activation() {

  //* Get all the posts
  $posts = get_posts( array( 'numberposts' => -1, 'post_status' => 'any' ) );
  foreach( $posts as $post ) {

    //* Generate a random date between January 1st, 2015 and now
    $random_date = mt_rand( strtotime( '1 January 2015' ), time() );
    $date_format = 'Y-m-d H:i:s';

    //* Format the date that WordPress likes
    $post_date = date( $date_format, $random_date );

    //* We only want to update the post date
    $update = array(
      'ID' => $post->ID,
      'post_date' => $post_date,
      'post_date_gmt' => null,
    );

    //* Update the post
    wp_update_post( $update );
  }
}
