The concert began at 12:00 British Summer Time (BST) (7:00 Eastern Daylight Time (EDT)) at Wembley Stadium in the United Kingdom. It continued at John F. Kennedy Stadium (JFK) in the United States, starting at 13:51 BST (8:51 EDT). The UK's Wembley performances ended at 22:00 BST (17:00 EDT). The JFK performances and whole concert in the US ended at 04:05 BST 14 July (23:05 EDT). Thus, the concert continued for just over 16 hours, but since many artists' performances were conducted simultaneously in Wembley and JFK, the total concert's length was much longer.
