Are the names "Wan Li" and "Wan Li" related?

Not directly involved. But they also have something in common, that is, their origins are all related to one person.

The perpetual calendar is the oldest solar calendar in ancient legends of China. In order to commemorate the calendar editor "Wannian" (the legendary young woodcutter, whose name is really good, people live up to its name), this calendar was named "Wannian Calendar". The perpetual calendar used now is actually an annual calendar that records the dates of a specific solar calendar or lunar calendar within a certain time range (such as 100 years or more), which is convenient for people in need to query and use, and has no direct connection with the original calendar.

Wanli is the title of Zhu Yijun (1573-1620) in Ming Shenzong, and it is a famous "Wanli Emperor" in Ming Dynasty. The name Wanli was used in the Ming Dynasty for 48 years, which was the longest in the Ming Dynasty. Huang Renyu, a historian, once wrote Fifteen Years of Wanli from the perspective of "Great Historical View".
