Hello, little explorers! Have you ever wondered why we have seasons, why the sun seems to move in the sky, and why we celebrate festivals at different times of the year? Well, the answer lies in something called natural solar terms. Let’s dive into this fascinating topic and discover the secrets of the natural solar terms, all in English!
What Are Natural Solar Terms?
Natural solar terms are a traditional way of dividing the year based on the sun’s position in the sky. They were created by ancient Chinese farmers to help them plan their crops and daily activities. There are 24 solar terms in total, each lasting about 15 days. These terms are used in many East Asian countries and are based on the solar calendar.
The Reasons for Solar Terms
The sun doesn’t just move in a straight line across the sky. It actually travels in an arc, which means it reaches different parts of the Earth at different times of the year. This causes the seasons and the natural solar terms.
