When you need pagination on a page (rather than an archive), you may want to introduce pagination.

Incorporate it into your query by detecting the page and modifying your query accordingly:

<?php
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$args = array(
  'post_type' => 'event',
  'posts_per_page' => 6,
  'paged' => $paged
);

// The Query
$the_query = new WP_Query( $args );
?>

Then, spit out the actual pagination:

<?php
$prev_arrow = is_rtl() ? '<span class="arrow-right"></span><span class="direction-text">Next</span>' : '<span class="arrow-left"></span><span class="direction-text">Prev</span>';
$next_arrow = is_rtl() ? '<span class="arrow-left"></span><span class="direction-text">Prev</span>
' : '<span class="arrow-right"></span><span class="direction-text">Next</span>
';
$total = $the_query->max_num_pages;
$big = 999999999; // need an unlikely integer
if( $total > 1 ) {
  if( !$current_page = get_query_var('paged') )
    $current_page = 1;
    if( get_option('permalink_structure') ) {
      $format = 'page/%#%/';
    } else {
      $format = '&paged=%#%';
    }
echo paginate_links(array(
  'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
  'format' => $format,
  'current' => max( 1, get_query_var('paged') ),
  'total' => $total,
  'mid_size' => 3,
  'type' => 'list',
  'prev_text' => $prev_arrow,
  'next_text' => $next_arrow,
));
}
}
?>
