Understanding the Results:
• GanZhi (Stem-Branch): A 60-year cycle system combining 10 Heavenly Stems (Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui) with 12 Earthly Branches (Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai).
• Zodiac: The 12 Earthly Branches correspond to 12 animals — Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig.
• NaYin (Five Elements): Each of the 60 GanZhi combinations is assigned a Five Element attribute (Metal, Wood, Water, Fire, Earth), forming 30 NaYin types like "Gold in Sea" or "Fire in Furnace."
• Solar Terms: The 24 Solar Terms divide the sun's path into segments, marking seasonal changes. UNESCO recognized them as Intangible Cultural Heritage in 2016.
• Yi/Ji (Auspicious/Inauspicious): Daily activities recommended or discouraged based on GanZhi combinations.
• Chong & Sha: The zodiac sign and direction in conflict with the current day. People born in that zodiac year should avoid major decisions.
• PengZu Proverbs: Ancient daily taboos organized by Heavenly Stems and Earthly Branches, e.g., "Jia: Do not open the warehouse" or "Zi: Do not divine."
• Day Officer (JianChu): A 12-day energy cycle: Build, Remove, Full, Flat, Stable, Hold, Break, Danger, Complete, Collect, Open, Close. "Complete," "Open," and "Stable" days are best for important matters.
• Yellow/Black Road: Yellow Road days have positive energy; Black Road days are better for simple tasks.
• 12 Two-Hour Periods: Ancient Chinese divided each day into 12 periods of 2 hours, each with different fortune attributes.
Solar vs. Lunar Calendar:
The Gregorian calendar is purely solar, based on Earth's orbit around the sun (365 or 366 days). The Chinese lunar calendar is a lunisolar system — it tracks the moon's phases (~29.5 days per month) while adding leap months to stay aligned with the solar year. This is why Chinese lunar dates shift relative to Gregorian dates each year.
GanZhi Stem-Branch System:
One of the oldest dating systems in the world, originating from the Shang Dynasty (~1600 BC). The 10 Heavenly Stems pair with 12 Earthly Branches to create 60 unique combinations (the Sexagenary Cycle). This system governs not just years but also months, days, and hours — forming the foundation of Chinese astrology (BaZi / Four Pillars of Destiny).
24 Solar Terms:
Developed through millennia of astronomical observation, the 24 Solar Terms precisely track the sun's position and mark seasonal transitions. In 2016, UNESCO added them to the Representative List of Intangible Cultural Heritage of Humanity. They remain vital for agriculture and daily life across East Asia.
Chinese Almanac (Huang Li):
The traditional Chinese almanac weaves together astronomy, calendar science, Yin-Yang theory, and Five Elements philosophy. It guides people in choosing auspicious dates for weddings, moving, travel, and business openings. While modern society views it as cultural heritage rather than strict guidance, it remains a living tradition practiced by millions.
