The perpetual calendar is the oldest solar calendar in ancient legends of China. The name of the perpetual calendar comes from a man named Wannian in Shang Dynasty, who was the editor of this calendar. In order to commemorate his achievements, he named this calendar "perpetual calendar". A perpetual calendar is an annual calendar that records the dates of specific solar and lunar calendars within a certain time range (such as 100 years or more), which is convenient for people in need to query and use.
