Who invented the perpetual calendar

The inventor of the perpetual calendar is uncertain. There is only one legend about this invention.

According to legend, a long time ago, there was a young man named Wannian who saw that the festivals at that time were very chaotic and wanted them to be accurate. One day, he went up the mountain to cut wood and sat in the shade to have a rest. Inspired by the movement of the shadow, he designed a coffin to measure the sun and calculate the time.

But it was raining and foggy at that time, which affected the measurement. Later, the dripping spring on the cliff aroused his interest, and he began to make five-story leaks. As time went on, he found that the length of the weather would repeat every 360 days.

In order to commemorate the achievements of 10 thousand years, the solar calendar was named "perpetual calendar" and named as the birthday star of the sun, moon and moon. In the future, people will hang up Shou Xingtu in China during the New Year, which is said to commemorate this venerable 10,000-year-old man.
