current date of an event for further use

just to confirm, did you mean using php code to get the event start date? if yes, we are quite limited with regards to custom coding as per the support policy but hopefully this user shared snippet can help you get started

function my_em_wp_query(){
	$args = array(
		'post_type' => 'event',
		'posts_per_page' => 100,
		'meta_query' => array( 'key' => '_start_ts', 'value' => current_time('timestamp'), 'compare' => '>=', 'type'=>'numeric' ),
		'orderby' => 'meta_value_num',
		'order' => 'ASC',
		'meta_key' => '_start_ts',
		'meta_value' => current_time('timestamp'),
		'meta_value_num' => current_time('timestamp'),
		'meta_compare' => '>='
	);

	// The Query
	$query = new WP_Query( $args );

	// The Loop
	while($query->have_posts()):
	$query->next_post();
	$id = $query->post->ID;
	echo '<li>';
	echo get_the_title($id);
	echo ' - '. get_post_meta($id, '_event_start_date', true);
	echo '</li>';
	endwhile;

	// Reset Post Data
	wp_reset_postdata();
}
add_shortcode('em_wp_query','my_em_wp_query');
