What is the Chinese calendar?

The historic Chinese calendar.

The Chinese calendar is one of the earliest countries in the world to invent the calendar. Its emergence has a certain impact on the development of China's economy and culture.

The lunar calendar, one of the traditional Chinese calendars, is also known as the "lunar calendar", "Yin calendar", "ancient calendar", "Huang calendar", "Xia calendar" and "Old calendar".

The lunar calendar is a lunisolar calendar. On the one hand, the moon orbits the earth once as a "month", and the average month length is equal to the "syzygous moon". This is the same principle as the lunar calendar, so it is also called the "lunar calendar". The wise Chinese people have worked hard for many years

The calendar and solar terms were invented.

According to legend, a long time ago, there was a young man named Wannian. One day, when he went up the mountain to cut firewood, the sun was too hot and he sat in the shade to rest.

Suddenly, he was inspired by the movement of tree shadows on the ground.

After returning home, he spent several days and nights designing a dial to measure the sun's shadow and measure the sky's time.

However, when it is cloudy, rainy or foggy, the measurement will be affected because there is no sun.

Later, the dripping spring on the cliff aroused his interest, and he started to make a five-layer clepsydra.

As time went by, he found that every three hundred and sixty days, the length of the day would repeat itself.

The king at that time was named Zu Yi, and the unpredictable weather also made him very distressed.

After Wannian heard about it, he couldn't help but bring the sundial and the clepsydra to see the king, and told Zu Yi the principles of the movement of the sun and the moon.

After Zu Yi heard this, Long Yan was very happy and thought it made sense.

So he left ten thousand years to build the Sun and Moon Pavilion in front of the Temple of Heaven, and built the sundial platform and leaky pot pavilion.

Zu Yi said to Wannian: "I hope you can accurately measure the laws of the sun and the moon, calculate the accurate morning and evening times, and create a calendar to benefit the people of the world." Winter goes and spring comes, year after year.

Later, after thousands of years of long-term observation and careful calculation, an accurate solar calendar was developed.

When he presented the solar calendar to his successor, his face was covered with silver whiskers.

The monarch was deeply moved. In order to commemorate Wannian's achievements, he named the solar calendar "Wannian Calendar" and named Wannian the sun, moon and longevity star.
