Start with two separate maps
A two-person BaZi reading does not need a single number at the top of the page to be useful. When you open the synastry view here, there is no compatibility percentage, statistical denominator, or relationship verdict waiting above the results. Instead, the browser calculates two complete four-pillar charts independently from each person's recorded local civil birth date, exact clock time, and explicit birth time zone, without uploading or storing those birth inputs. Before entering a second birth record, ask the other person's permission, and treat the on-page display as two distinct structural records sitting side by side.
Begin your reading by looking at each chart on its own. Each person has four pillars—year, month, day, and hour—containing eight visible characters in total, with each Heavenly Stem and each Earthly Branch's principal element contributing one count to the five-phase bars beneath that chart. A bar showing three out of eight simply means three of those eight visible characters are assigned to that element; it does not measure personality percentages, chart strength, or what someone lacks in life. Looking at the two charts separately keeps each person's full layout in view before you examine how the symbols interact.
Read the Day Master relation before the details
Once you have looked over the two individual layouts, move to the Day Master heading. The Day Master is the Heavenly Stem of the day pillar. In a two-person comparison, the tool compares the two Day Masters and names their structural relationship: they might be the exact same stem, two different stems sharing the same phase, or two phases connected by the traditional generating or regulating cycle.
For example, in an invented schematic pairing where Person A has a Bing Fire Day Master and Person B has a Wu Earth Day Master, the page notes a generating relationship because Fire precedes Earth in the traditional generating sequence: Wood, Fire, Earth, Metal, Water, Wood. If Person A had Wood and Person B had Earth, the page would note a regulating link from the sequence Wood, Earth, Water, Fire, Metal, Wood. That directional label describes how two calendar symbols relate in traditional convention; it does not make one person a permanent giver or receiver, and it sets no real-life obligations between you.
Scan the sixteen positional checks
Next, look down at the interaction lists on the results page. Rather than blending the two charts into a single composite, the calculator scans all sixteen cross-chart pillar-position pairs—comparing Person A's year, month, day, and hour against Person B's year, month, day, and hour. It flags conventional stem combinations, branch combinations, and branch oppositions by naming the exact pillar positions and characters involved, without displaying a transformation element or recalculating the five-phase bars.
Suppose an invented on-page list shows a branch combination between Person A's month branch and Person B's hour branch, alongside a branch opposition between their two year branches. Because a character can repeat within a chart, the same symbol pair can appear more than once across different positional pairs. Treat both combinations and oppositions as conventional symbolic patterns on the grid rather than promises of harmony or warnings of guaranteed conflict.
Turn the screen into an optional conversation
To finish the reading, pick one line from the on-page results—or download the two-person reflection card, which holds only the two Day Master labels and a single open question—and test it against ordinary life. You might ask, "The page says our Day Masters sit in a regulating relation; does that remind you of how we plan a trip, or not at all?"
A practical chart reading always leaves room for a flat no. If you both look at a flagged branch opposition or a Day Master link and decide, "That symbol does not sound like us," cross it off your notepad and move on. The page supplies traditional calendar structure; the two of you decide which lines are worth talking about.
