Compatibility starts with two complete charts
Each person's Saju chart is built from the year, month, day and hour pillars. A compatibility reading compares the relationship between those structures rather than reducing the match to a single sign.
Day Master chemistry is one starting point
The Day Master gives each chart a central element reference. Comparing two Day Masters can offer a simple first clue about whether the relationship feels naturally supportive, similar, energizing or tense.
A pairing can feel magnetic because it creates strong contrast or pressure. That same pattern can also produce friction. Traditional compatibility reading therefore looks beyond attraction alone.
The Five Elements add context
Wood, Fire, Earth, Metal and Water can support or regulate one another through traditional generating and controlling cycles. When comparing two charts, a reader may ask whether one person's dominant tendencies reinforce what the other lacks, or whether the same interaction repeatedly creates pressure.
What a fuller love reading looks at
Beyond Day Master chemistry, a richer interpretation considers emotional rhythm, attraction patterns, recurring tension, timing and what each person appears to need from a relationship. This is why two people with the same element pairing can still have very different relationship dynamics.
Can Saju predict whether a relationship will last?
It should not be treated as a factual guarantee of relationship success or failure. A useful way to use compatibility readings is as a reflective framework: notice what kinds of differences create attraction, what kinds create stress, and what each person may need to communicate more clearly.
