二十四节气：中国的传统时间系统
二十四节气是中国古代农耕文明的产物，是依据太阳在黄道上的位置来划分的。二十四节气反映了太阳直射点的周年运动，以及由此而带来的气候、物候等变化，对农业生产具有重要的指导意义。
二十四节气分为四时，即春、夏、秋、冬。每个季节有六个节气，分别是：
• 春季：
• 立春（Spring Begins）
• 雨水（Rain Water）
• 惊蛰（Awakening of Insects）
• 春分（Spring Equinox）
• 清明（Pure Brightness）
• 谷雨（Grain Rain）
• 夏季：
• 立夏（Summer Begins）
• 小满（Grain Filling）
• 芒种（Grain in Ear）
• 夏至（Summer Solstice）
• 小暑（Minor Heat）
• 大暑（Major Heat）
• 秋季：
• 立秋（Autumn Begins）
• 处暑（End of Heat）
• 白露（White Dew）
• 秋分（Autumn Equinox）
• 寒露（Cold Dew）
• 霜降（Frost's Descent）
• 冬季：
• 立冬（Winter Begins）
• 小雪（Minor Snow）
• 大雪（Major Snow）
• 冬至（Winter Solstice）
• 小寒（Minor Cold）
• 大寒（Major Cold）
