BEHIND THE BIRTHDAY
Explore the date-based chart before entering your own birthday. These are symbolic reading themes, not verified personality traits.
Each column pairs a heavenly stem with an earthly branch. Birth time is unknown: the hour pillar is excluded. The engine assumes noon for the date calculation; solar-term boundaries may depend on the actual birth time.
Wood is a symbol of growth and new directions. Read it as a theme of developing ideas and making room for fresh starts.
Basis: the heavenly stem in the Day column above. This is one lens, not a complete reading.
Fan prompt: Which new challenge or change from this member stayed with you?
Six visible symbols, with equal weight. This is a count, not a strength or talent score.
Most represented: Wood · Water
Ties are shown together. A zero does not imply a missing skill or personal flaw.
The same day element appears in BEOMGYU, HUENINGKAI's chart too.
Compare one chart feature, not a ranking of personalities or relationships. Open a member to explore their full date-based profile.
YOUR BIRTHDAY. YOUR FANDOM.
Enter your birthday to compare every member. No account or birth time needed.
A different date here will not change your Toolwyn profile.
Calculated on this device. Your profile birthday is reused; edits here stay only while browsing K-pop. No birthday is included in analytics, links or cards.
A LITTLE CONTEXT
Saju is a Korean birth-chart tradition. This fan experience compares the year, month and day of two birthdays using traditional element and day-branch relationships. It is a conversation starter, not evidence about an idol’s personality or feelings.
We compare day elements (supporting +3, same +1, contrasting −2), day branches (harmonizing +3, opposing −2, otherwise 0), and missing elements supplied by the other chart (three or more +2, one or two +1). The total, from −4 to 8, is mapped to 0–100. A score is an entertainment index, not a percentage chance.
No. Birth times are unverified, so hour-pillar elements are excluded for both you and the idol. The engine uses noon to resolve the calendar date. Only the Gregorian birth date is used; gender is not part of these matching rules.
Your existing Toolwyn profile birthday can prefill the form. Lunar profiles are converted to Gregorian dates. Edits made here stay in memory while you browse K-pop and do not change your saved profile. Your date is processed in your browser. Shared images contain the selected idol and score, but no birthday. Challenge links open the idol’s page so your friends can get their own results.
These traditional rules have a limited set of outcomes. Ties are expected and receive the same rank. A lower score means a different symbolic combination, not that you are a worse fan or incompatible in real life.
