Chunfen (春分) reflects the changing of seasons. The day of Chunfen falls exactly in mid-spring around March 20-22. On this day, so as on Qiufen in autumn, the sun shines directly on the equator, making the days and nights equal in length everywhere in the world. After Chunfen, the days are longer and the nights shorter.
People often use the weather of Chunfen to forecast the weather of the future, as a number of old sayings go: "If it rains on Chunfen, it might be a heavy rain; a cold Chunfen might bring a cold Qiufen; a warm Chunfen might bring a cold Qingming."
Many people choose the days around Chunfen to go on outings, to enjoy the lovely sunshine and spring scenery.
