3 Characteristics of the Intercalary month
Weather and Climate
Weather and Climate
The Intercalary month marks a significant shift in temperatures. It is considered the start of the yin phase of the year, when the sun moves southward, leading to a decrease in solar radiation and a shift toward yin dominance.
The characteristic climate during this term is mild and slightly cool, with a hint of dryness. The sun shines warmly but not scorchingly, and gentle breezes bring a pleasant coolness. Nights turn slightly chilly, and rainfall remains low while humidity rises, creating an extremely comfortable atmosphere. This solar term is regarded as the most pleasant of the 24 solar terms, making it ideal for outdoor activities.
Adaptations of Plants
Adaptations of Plants
As the days and nights during the Intercalary month approach equilibrium, with less pronounced disparities, plants undergo adaptations to acclimate to the changing environment.
The substantial decrease in temperature, sunlight, and humidity, coupled with low rainfall, significantly impacts the process of photosynthesis in plants. Consequently, most trees don colorful autumn foliage, cacti transform their leaves into spines to conserve water, and numerous plants accumulate nutrients in the form of tubers, stems, or roots.
The Intercalary month coincides with the harvest season for cereal crops, the ripening of fruits, and the dispersal of seeds, setting the stage for the upcoming spring.
Food Storage by Animals
Food Storage by Animals
During this term, animals actively prepare for the impending winter by storing fat to stay warm and maintain energy reserves, stockpiling food, and seeking shelter. Many bird species commence their southward migration to escape the cold.
It is also the breeding and mating season for livestock and wild animals. Insects and worms enter their reproductive phase, with a new generation of insects set to emerge during the “Kinh Trập” solar term.
4 Significance of the Intercalary month
In Divination
Significance in Divination
In divination, the Intercalary month occurs in the seventh lunar month, which falls within the autumn season and corresponds to the “Bĩ” hexagram.
Autumn is associated with the dominance of metal (金), symbolizing infinite benefits derived from the creation of wealth. It is also the season when the “Qian” and “Ba Gua” hexagrams emerge.
According to the five elements theory, the dominance of metal (金) restrains wood (木), leading to its decline. Metal (金) generates water (水), resulting in its prosperity. Earth (土) generates metal (金), causing its depletion, while fire (火) restrains metal (金), leading to its imprisonment. During the Intercalary month, the “Zhen” and “Sun” hexagrams, representing wood (木), are subdued.
In Astrology
Significance in Astrology
The Intercalary month corresponds to the seventh lunar month, known as the “Monkey Month,” which possesses yang energy and is associated with metal (金). However, as temperatures drop, the cool breeze can easily trigger respiratory ailments.
During this term, yin thrives while yang wanes, casting a somber mood over humanity. Additionally, according to folklore, this period marks the release of souls from the underworld, allowing them to return to the mortal realm, resulting in an abundance of yin energy.
Influenced by the tragic love story of Mr. Nâu and Mrs. Nâu, a popular folk tale, the Intercalary month is considered inauspicious for weddings and groundbreaking ceremonies.
Adhering to the age-old belief that “superstition brings good luck, and precaution brings safety,” people generally refrain from undertaking significant endeavors during this time to avoid any potential negative influence of the prevailing yin energy.
