FAQs About The Twenty-Four Solar Terms

What is the significance of the Twenty-Four Solar Terms in Chinese culture?

The Twenty-Four Solar Terms serve as a time knowledge system developed through observing the sun’s annual movement, guiding agricultural practices and reflecting seasonal changes.

 

Originating from the Yellow River basin, they evolved during ancient China’s farming civilization and were fully established by the Qin and Han dynasties as part of the Taichu Calendar.

The system divides Earth’s orbit around the sun into 24 equal segments, each spanning 15° of solar longitude, starting from the Spring Equinox at 0°.

 

They represent changes in temperature (e.g., Major Heat), rainfall (e.g., Rain Water), seasonal transitions (e.g., Spring Begins), and agricultural activities (e.g., Grain Rain).

In 2016, the Twenty-Four Solar Terms were inscribed on UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity, reflecting their cultural value.
