Regarding the Harmonious Optimization of Timing for Intimacy
This guide outlines traditional Chinese beliefs on timing for intimacy. It advises avoiding key inauspicious periods, such as specific solar term days, new/full moons, dates clashing with your zodiac, the “Nine Poison Days” in the 5th lunar month, and extreme weather. The ideal time is a harmonious evening (9-11 PM). A modern perspective reminds us to prioritize mutual consent and emotional connection over strict adherence to taboos.
Category One: Absolute Contraindicated Times (Strongly Not Recommended)
These time points are considered periods of chaotic, transitioning, or intensely clashing energies between heaven and earth. Engaging in intimacy during these times is believed to easily stir negative energies, harming luck and health.
1. The Four Departure Days & Four Severance Days
Source: Special days within the 24 Solar Terms, usually clearly marked in perpetual calendars.
Definition:
Four Departure Days: The day before the Spring Equinox, Autumn Equinox, Summer Solstice, and Winter Solstice. Signifies “departing” from the solar term, with chaotic energy.
Four Severance Days: The day before the Beginning of Spring, Beginning of Summer, Beginning of Autumn, and Beginning of Winter. Signifies the “severance” of the previous season, with interrupted energy.
Impact: Traditionally, these days are seen as times when the energies of heaven and earth are in transition and chaos. It is unfavorable for major activities (including intimacy), as it may lead to unstable fortune and physical depletion.
2. New Moon & Full Moon Days (Lunar Day 1, 15, and surrounding days)
Source: Periods of the strongest gravitational influence of the moon on Earth (tides).
Definition:
New Moon Day (Shuo Ri): Lunar day 1, when the moon is between the sun and Earth (sun and moon in the same palace).
Full Moon Day (Wang Ri): Lunar day 15, when Earth is between the sun and moon (sun and moon opposite each other).
Impact: As the human body is approximately 70% water, it is influenced by lunar gravity, leading to significant fluctuations in emotions and qi-blood. On New Moon days, qi-blood is deficient; on Full Moon days, qi-blood is excessive and easily agitated. Intimacy during these times is thought to severely deplete vital essence, spirit, and energy (jing qi shen), not conducive to health cultivation or stable fortune.
3. Days that Clash, Conflict with, or Harm One’s Zodiac Animal
Source: Calculated based on an individual’s birth date and time (Eight Characters).
Definition: Check a perpetual calendar. If the Earthly Branch of a particular day has the following relationship with your zodiac animal (Year Branch):
Clash Day (Chong): Zi-Wu clash, Chou-Wei clash, Yin-Shen clash, Mao-You clash, Chen-Xu clash, Si-Hai clash. Signifies intense change and conflict.
Conflict Day (Xing): E.g., Yin-Si-Shen conflict, Chou-Wei-Xu conflict, Zi-Mao conflict, etc. Signifies disputes, injury/illness, or torment.
Harm Day (Hai): Zi-Wei harm, Chou-Wu harm, Yin-Si harm, Mao-Chen harm, Shen-Hai harm, You-Xu harm. Signifies hidden damage or sowing discord.
Impact: Intimacy on these days is believed to intensify the clash against one’s own destiny pattern, potentially leading to marital arguments, health issues, or unexpected financial loss.
4. Certain Days in the Fifth Lunar Month (Traditionally called “Poisonous Month”)
Source: Traditional folklore considers the fifth lunar month as a time of struggle between Yin and Yang, separation of life and death.
Important Taboo Days:
5th day of the 5th month (Dragon Boat Festival): The first of the “Nine Poison Days,” with numerous taboos.
The “Nine Poison Days”: Typically refers to the 5th, 6th, 7th, 15th, 16th, 17th, 25th, 26th, and 27th days of the fifth lunar month. These nine days are considered harmful to the body, depleting vital energy and essence. It is advisable to rest separately and quietly cultivate health.
5. During Extreme Weather (Thunderstorms, Torrential Rain, Heavy Snow, Gale-force Winds)
Source: The concept of correspondence between heaven and humanity.
Impact: During such times, the Yin and Yang energies of heaven and earth are fiercely contending, creating turbulent and unsettled energy fields. Intimacy is thought to disturb the body’s internal microcosm, easily attracting negative energies, potentially leading to heart palpitations, nightmares, and in the long term, detrimental effects on fortune.
Category Two: Times Requiring Relative Caution (Recommended to Avoid)
While not as severe as Category One, it is best to avoid these times from the perspective of health cultivation and smooth fortune.
1. The Day of Solar Term Exchange Itself
Source: Similar to the “Four Departure & Severance Days,” but while the day of the solar term itself involves energy adjustment, it is less intense than the day before. It remains a sensitive period.
2. From the 23rd Day of the 12th Lunar Month (Sending off the Kitchen God) to Lunar New Year’s Eve
Source: Folk beliefs.
Impact: This period is when various deities are said to ascend to heaven to give reports, leaving the human realm without divine oversight—referred to as “nothing is forbidden.” However, it is also considered susceptible to disturbance by negative influences. Quietude is preferred over activity, and intimacy should also be approached with caution.
3. When Both or One Partner is in Extremely Poor Physical/Mental State
Source: Traditional Chinese Medicine health preservation view.
Situations: E.g., when one or both partners are recovering from serious illness, excessively fatigued, in extremely low spirits (after great grief, anger, or fear), or intoxicated.
Impact: The body’s vital energy (Zheng Qi) is insufficient at such times. Intimacy can greatly deplete vitality, not only hindering health recovery but also introducing negative energy into the intimate relationship, affecting both partners’ fortune.
Summary & Recommendations
Core Principle: Follow the timing of nature, harmonize for health cultivation.
Preferred Auspicious Time: In theory, the most suitable time is during a peaceful evening (Hai hour, 9 PM – 11 PM) when both partners are happy, physically comfortable, and the environment is tranquil. At this time, Yang energy recedes, Yin energy gradually rises, and Yin and Yang commune, aligning with the natural order.
Consultation Tool: When planning important dates, consult a professional “Chinese almanac” or “perpetual calendar.” Beyond checking if it’s “suitable for marriage/wedding,” be sure to avoid all the contraindicated days mentioned above, especially those that clash with your zodiac animal.
Most Important Point: The above rules stem from traditional cultural systems. A modern perspective emphasizes mutual consent, emotional connection, and health status. If one becomes overly superstitious about taboos and neglects the fundamental elements of love and respect, it can create pressure and damage the relationship, which would be the greatest harm to “fortune.”
