Compare BaZi Charts and Annual, Monthly or Daily Pillars
A BaZi comparison places both charts under the same calendar rules and checks stem and branch relations across their pillars, including complete or partial birth records.

Read corresponding layers
Compare the Day Masters first, then the seasonal months and day branches. Year animals are one layer of the comparison; they do not replace the other pillars.
Read combinations in context
A pair can have more than one branch relation. A harmony and a harm, for example, describe different structures. Keep every returned relation with its two reference branches rather than reducing it to a score.
