The ancient Chinese created a calendar with 24 segments based on both lunar and solar events. In 1685, the Chinese 24-season calendar was rewritten by the Japanese astronomer Shibukawa Shunkai and it became 72 seasons. These 72 seasons "offer a poetic journey through the Japanese year in which the land awakens and blooms with life and activity before returning to slumber."
