The ancient yellow calendar is a perpetual calendar. The perpetual calendar is the oldest solar calendar in ancient legends of China. A perpetual calendar is an annual calendar that records the dates of specific solar and lunar calendars within a certain time range (for example, 100 years or longer), which is convenient for people in need to query and use.

Modern perpetual calendars can simultaneously display various calendars such as Gregorian calendar, lunar calendar and official calendar, and can also contain various functional information such as good or bad luck, holidays and reminders, which is very convenient for people to query and use.
