What is Birth Date Selection? Gifting Your Child a Fortunate Destiny
A comprehensive guide for parents planning an elective C-section. Solzigi explains how to choose the optimal date and time to gift your child the best possible BaZi (Four Pillars of Destiny) chart.
What if you could gift your child a head start in life?
Every parent wishes for their child to lead a happy and successful life.
If you are a parent planning an elective Cesarean section, you might have asked yourself this question:
"If I have to schedule the surgery anyway, wouldn't it be better to choose a lucky day and time for the baby to be born?"
This is the essence of Birth Date Selection (Taekil).
What is Birth Date Selection?
The Concept
Birth Date Selection involves analyzing the potential birth dates and times through the lens of BaZi (Four Pillars of Destiny) to find a moment that provides the most auspicious birth chart for the child.
A BaZi chart consists of four pillars determined by the Year, Month, Day, and Hour of birth. Since the Year and Month are usually fixed by the pregnancy term, being able to select the Day and Hour allows you to essentially "design" a significant portion of your child's destiny.
Natural Birth vs. C-Section
- Natural Birth: The baby decides when to enter the world. Date selection is generally not applicable here.
- C-Section: You can adjust the birth time within the range permitted by medical safety.
๐ก Therefore, Birth Date Selection is a service primarily designed for parents planning an elective C-section.
Why Choose a Birth Date?
1. To Gift a "Tailwind" for Life
A birth chart doesn't dictate everything, but a good chart acts like a tailwind in the journey of life.
Just as a ship reaches its destination more easily with the wind at its back, a balanced birth chart helps a child unlock their innate potential with fewer obstacles.
2. To Avoid "Stormy" Days
The core of date selection isn't just finding the "best" day, but avoiding the "worst" ones.
In metaphysics, certain days or hours contain volatile energies known as Clashes (Chung), Punishments (Hyeong), or Harms (Hae). Simply avoiding these turbulent times can provide a much smoother foundation for your child's life.
3. For the Parents' Peace of Mind
Knowing you did your absolute best gives parents a sense of psychological stability.
Of course, a child is precious regardless of when they are born. However, if you have the option to choose, it is a parent's natural instinct to want to select the most auspicious time available.
Conditions for a High-Quality Chart
Solzigi analyzes the following elements comprehensively to determine the best time.
1. Quality of the Chart Structure (Gyeokguk)
The Structure (Gyeokguk) represents the framework of the chart. A "Clear Structure" implies a smooth path to social success, while a "Broken Structure" may indicate instability.
| Structure Status | Meaning | Score Impact |
|---|---|---|
| Clear (Established) | Stable framework, high potential | +20 pts |
| Neutral | Neither clear nor broken | No change |
| Broken | Unstable framework | -10 pts |
2. Balance of the Five Elements (Ohaeng)
A high-quality chart features a harmonious balance of the five elements: Wood, Fire, Earth, Metal, and Water.
| Element Status | Meaning | Score Impact |
|---|---|---|
| All 5 Present | Harmonious, versatile | +8 pts |
| 4 Elements (Slight Imbalance) | Slightly skewed | -8 pts |
| Excessive (5+ of one type) | Severe imbalance | -15 pts |
| 1 Missing | Lacking specific energy | -6 pts |
| 2+ Missing | Severely lacking balance | -10 pts |
3. Seasonal Balance (Johu)
This refers to the temperature regulation of the chart. For example, a baby born in the heat of summer needs "Water" energy to cool the chart; otherwise, the balance is lost.
| Season | Required Energy | Impact if Missing |
|---|---|---|
| Mid-Summer (Hot) | Water (Cooling) | -12 pts if missing |
| Mid-Winter (Cold) | Fire (Warming) | -12 pts if missing |
| Balanced | Extremes are neutralized | +8 pts |
4. Presence of Noble Stars (Guiin)
Noble Stars represent helpful people or divine protection that aids the child during difficult times.
| Noble Star | Meaning | Score Impact |
|---|---|---|
| Heavenly Noble | The highest positive star, great fortune | +10 pts |
| Heavenly Virtue | Avoidance of disaster, blessings | +8 pts |
| Monthly Virtue | Benevolence, popularity | +6 pts |
| Academic Noble | Intelligence, academic success | +6 pts |
5. The 12 Energy Phases (12 Unseong)
This measures the strength of the "Day Master" (the child's core self).
| Phase | Meaning | Score Impact |
|---|---|---|
| Thriving (Geonrok) | Independence, leadership | +12 pts |
| Peak (Jewang) | Maximum energy, success | +12 pts |
| Birth (Jangsaeng) | New beginnings, creativity | +8 pts |
| Maturing (Gwandae) | Social skills, vitality | +6 pts |
| Death/Sickness | Health precautions needed | -5 pts |
| Grave/Extinction | Weak energy | -8 pts |
What to Avoid: Signs of a Difficult Chart
1. Internal Clashes (Chung)
Clashes represent conflicting energies. The following clashes, in particular, can indicate instability.
| Type of Clash | Impact | Score Impact |
|---|---|---|
| Month-Day Clash | Emotional ups and downs, instability | -20 pts |
| Day-Hour Clash | Inner conflict, issues in later years | -15 pts |
| Year-Month Clash | Unstable childhood or family environment | -12 pts |
2. Destruction (Pa) and Harm (Hae)
Destruction scatters energy, while Harm hinders relationships.
| Type | Meaning | Score Impact |
|---|---|---|
| Destruction (Pa) | Lack of persistence, patience required | -6 pts |
| Harm (Hae) | Interpersonal relationship caution | -5 pts |
Solzigi's Analysis Methodology
Analysis Scope
Based on your expected due date, Solzigi analyzes a range of ยฑ1 day (Total 3 days). We calculate 12 Double-Hours ร 3 Days = 36 Time Slots in detail.
๐ก What is a Double-Hour (Sijin)? In Asian metaphysics, time is measured in 2-hour blocks.
| Sijin | Time Range | Sijin | Time Range |
|---|---|---|---|
| Rat (Zi) | 23:00-00:59 | Horse (Wu) | 11:00-12:59 |
| Ox (Chou) | 01:00-02:59 | Goat (Wei) | 13:00-14:59 |
| Tiger (Yin) | 03:00-04:59 | Monkey (Shen) | 15:00-16:59 |
| Rabbit (Mao) | 05:00-06:59 | Rooster (You) | 17:00-18:59 |
| Dragon (Chen) | 07:00-08:59 | Dog (Xu) | 19:00-20:59 |
| Snake (Si) | 09:00-10:59 | Pig (Hai) | 21:00-22:59 |
Time Correction: True Solar Time
For an accurate chart, we must use True Solar Time, not just the time on the clock. Solzigi applies two critical corrections:
- Longitude Correction: Adjusts for the difference between your birth location's longitude and the standard time meridian.
- Equation of Time: Adjusts for the variation in the sun's position due to the Earth's elliptical orbit.
Example: A baby born in Seoul (Longitude 127ยฐ) requires a correction of approximately -32 minutes from standard KST.

Important Considerations
1. Medical Safety is Priority #1
Birth Date Selection must only be considered within the limits set by your medical team.
The health of the mother and baby is far more important than any horoscope. Please tell your doctor, "If possible, we prefer this time frame," but always remain flexible to medical necessities.
2. Destiny is a Map, Not the Territory
A BaZi chart is a map of potential. No matter the chart, a child's life is shaped by parental love, upbringing, and their own free will.
A good chart is like a sturdy boat with a tailwind, but the person steering the boat is the captain (your child).
3. Be Realistic
If the #1 recommended time is 3:00 AM, it might be impossible to schedule a surgery then. In that case, it is wise to choose a realistic option from the Top 2~10 list.

Frequently Asked Questions
Q: Is this useful for natural birth?
Natural birth times cannot be controlled. However, knowing the favorable and unfavorable days around your due date can help with mental preparation and peace of mind.
Q: I'm having twins. Will they have different charts?
Yes, they can. Even if born on the same day, if the birth time crosses into a different Double-Hour (Sijin), the Hour Pillar changes. This can completely alter the structure and interpretation of their lives.
Q: Can I use this for a birth overseas?
Absolutely. Solzigi calculates True Solar Time based on the longitude and time zone of the specific city anywhere in the world.
Q: What if the doctor's schedule doesn't match the best time?
Medical safety comes first. If the hospital's available slot is safe, please proceed with that time. The health of the mother and baby outweighs any astrological reading.
