Why is there no lottery in the perpetual calendar?

The perpetual calendar did not draw lots because it did not meet the requirements of socialist core values. The perpetual calendar is the oldest solar calendar in ancient legends of China, which records the dates of specific solar calendars and lunar calendars within a certain time range (such as 100 years or more). Because lottery belongs to feudal superstition and does not meet the requirements of socialist core values, there is no lottery.
