The fifteenth solar term of the Chinese calendar, Cold or White Dew (Bái Lù), begins on Saturday, September 7, 2024. It is also the third solar term of autumn. During this time, the climate gradually shifts from early autumn to late autumn. White Dew refers to the condensation of water vapor on the ground due to the drop in temperature. Bái Lù signifies colder weather, especially with a noticeable temperature difference between morning and evening.
Chinese Calendar:
In the Chinese solar calendar, White Dew marks the start of the eighth month, known as 酉 You, corresponding to the Rooster, the 10th Earthly Branch.
Yin and Yang:
White Dew represents a transition from warm to cold. It is a period where Yang Qi gradually declines, while Yin Qi increases, signaling a shift from Yang to Yin energy.
As illustrated by the hexagram of the month:
Hexagram of the Month:
In the Yi Jing, there are 12 sovereign hexagrams corresponding to the 12 Earthly Branches. The month of September is associated with the eighth solar month, the Earthly Branch 酉 You (Rooster), and Hexagram 20 – Contemplation (觀 Guān).
Taoist Energetics, Seasons, and the Five Elements:
In Taoist energetics, the solar period of White Dew is the third phase of autumn, governed by the Metal element. During this time:
- Metal is prosperous.
- Water is generated by Metal, making it strong.
- Earth generates Metal, but as Metal is in season, Earth is weakened.
- Fire controls Metal but is weakened by the strength of Metal, making Fire subdued.
- Wood is controlled by the strong Metal, making Wood exhausted.
This energetic shift marks the deepening of autumn and the dominance of Metal in the cycle of the five elements.
