The traditional Chinese lunar calendar divides the year into 24 solar terms. Cold Dew, (Chinese: 寒露), the 17th solar term of the year, begins this year on Oct 8 and ends on Oct 23.
At this time, temperatures are much lower than in White Dew in most areas of China. The dew is greater and colder and there will be less rain. Autumn crops will be ripe.
After the Cold Dew,
the dewdrops that gather
the essence of heaven
and earth coagulate because of the
and give off a slightly cold light.
This is where the name
"Cold Dew" comes from.
