Age compatibility — understand favorable and difficult points
Age compatibility explains favorable and difficult points for the situation you enter. Comparing two people and examining a year for building a home use different criteria.
What to prepare
Prepare the birth year and choose the purpose. For two people, provide both sets of information. For a planned year, enter that year rather than substituting the current one.
Method
The app compares heavenly stems, earthly branches, elements and the rules in the selected branch. Stems and branches form the traditional year name; nạp âm groups years by an elemental classification. For home building, Kim Lâu, Hoang Ốc and Tam Tai are considered separately under the current rules.
How to read the result
Read each criterion and why it is favorable or difficult. A favorable stem relationship does not make every other criterion favorable. Birth years alone do not supply the year, month, day and hour needed for a complete Four Pillars reading.
Example
Two people enter their birth years to consider compatibility. Read the stems, branches and elements separately, then relate the points to an actual issue, such as agreeing on a work schedule. One favorable label does not mean they agree in every area.
Frequently asked questions
Are two birth years enough to describe the whole relationship?
They are sufficient for the supported birth-year comparison. They do not provide circumstances, communication habits or all the information for a birth chart.
Can changing the planned year change the result?
Yes: that year is part of the information being examined. Editing information creates a new reading; the previous one keeps its saved information and text.
Next step
Confirm the birth years, situation and planned year before starting. Note the criterion you want to clarify alongside your actual plan.
