Seven appears to be a universally lucky or holy number. There are many terms that include the number seven like: the seven wonders of the world, seven deadly sins, seven heavenly virtues, seven days of the week, and so on. "Seven Samurai (Shichi-nin no Samurai)" is a classic Japanese movie directed by Akira Kurosawa, which was remade into "The Magnificent Seven." Buddhists believe in seven reincarnations. The Japanese celebrate the seventh day after a baby's birth, and mourn the seventh day and seventh week following a death.
