@hatsumatsu ‘s solution works great, except I can’t seem to be able to make it work with a date field assigned to a custom taxonomy. I’m using it for a date picker like this:

/**
 * Convert values of ACF core date pickers from Ymd to timestamp
 * @param  string $value   unmodified value
 * @param  int    $post_id post ID
 * @param  object $field   field object
 * @return string          modified value
 */
function acf_save_as_wp_date( $value, $post_id, $field  ) {
    if( $value ) {
        $value = strtotime( $value );
    }

    return $value;    
}

add_filter( 'acf/update_value/type=date_picker', 'acf_save_as_wp_date', 10, 3 );

/**
 * Convert values of ACF core date pickers from timestamp to Ymd
 * @param  string $value   unmodified value
 * @param  int    $post_id post ID
 * @param  object $field   field object
 * @return string          modified value
 */
function acf_load_as_acf_date( $value, $post_id, $field  ) {
    if( $value ) {
        $value = date( 'Ymd', $value );
    }

    return $value;    
}

add_filter( 'acf/load_value/type=date_picker', 'acf_load_as_acf_date', 10, 3 );

Tried adding the name of taxonomy, like $value = strtotime( $value, 'event_dates' ); and $value = date( 'Ymd', $value, 'event_dates' ); as well, but I don’t know if that’s at all correct way of doing it.
