小寒是二十四节气中的第23个节气，也是冬季的第5个节气。每年公历1月5-7日，当太阳到达黄经285°时为小寒。小寒标志着子月的结束和丑月的开始。小寒虽然名称中带有"小"字，但在很多地区，小寒时节的气温往往比大寒更低。这一名称的"小"是相对于大寒而言，反映的是节气序列而非实际气温。小寒处于"数九"中的"三九""四九"时段，是一年中最寒冷的时期。民谚云"小寒大寒，冷成冰团"形象地说明了这个时期的严寒程度。小寒虽然寒冷，但却蕴含着生机，这是"否极泰来"哲学的生动体现。古人说"三九"是最冷的时候，而小寒节气通常处于三九时期，所以小寒往往是一年中最冷的节气。

Minor Cold (Xiaohan) is the 23rd solar term among the 24 solar terms and the fifth solar term of winter, occurring around January 5-7 when the sun reaches 285 degrees celestial longitude. Minor Cold marks climate entering year's coldest period. As the saying goes, "Minor Cold, Major Cold, freezing into ice balls." Minor Cold period often coincides with "third nine, fourth nine"—year's coldest time. Though called "Minor" Cold, temperatures in many regions actually reach annual minimum during this period. "Minor" relative to following Major Cold, but actual temperatures often differ little or Minor Cold may even be colder. Minor Cold represents winter's deepening, with increasing cold, everything hibernating, vitality concealing. In traditional Chinese culture, Minor Cold is an important solar term marking midwinter arrival and spring approaching. Though climate is harsh, Minor Cold also contains hope for spring's imminent arrival.
