Your Day Pillar — the most personal element of your saju chart — changes every year. Find yours below.

In saju, your Day Pillar (일주/日柱) represents your core self — who you are at the deepest level. Unlike Western astrology's sun sign, which stays the same for everyone born in the same month, the Day Pillar changes every single day and cycles through 60 unique combinations. Two people born on December 18 in different years carry different Day Pillars, different energies, and different structural tendencies.

December falls under the Rat branch (子/자) in saju, governed by Yin Water energy. This month energy shapes your social instincts and career tendencies. But your Day Pillar shapes you.

Spotlight: December 18th by Birth Year

1990
丁巳
Yin Fire

Yin Fire as your Day Pillar is the candle flame, the lamplight, the focused warmth. You see details others miss and bring clarity to confusion. Your intensity is precise rather than explosive.

1995
癸未
Yin Water

Yin Water as your Day Pillar is the dew, the spring, the quiet stream. You are perceptive, adaptable, and capable of finding paths through obstacles that seem impassable. Your mind is quick, and your intuition is rarely wrong.

2000
庚戌
Yang Metal

Yang Metal as your Day Pillar is the sword, the axe, the tool that shapes the world through decisive action. You are direct, principled, and capable of cutting through what others avoid. Your edge is your greatest asset and your greatest risk.
