Tools that take a birth date or a name and show you exactly what a traditional system says about it. The four pillars are cut by solar terms and true solar time, the Thai Thaksa wheel by the sunrise boundary, and the name and talisman tools show every step of their arithmetic. None of them predicts anything; they compute what the rule produces.
Four tools that take a birth date or a name and compute what a traditional system says about it. Saju rewrites a birth moment as four pillars of stems and branches, Thai astrology (Thaksa) lays eight houses out from the weekday you were born on, name compatibility reduces two names by a ladder of stroke counts, and the talisman tool draws an image from a wish and a name.
What they share is that they show the working, not just the verdict. Every rule applied is printed on screen, so when another site disagrees you can see exactly which step differs.
They come from different families. Saju is the Chinese sexagenary system; Thai astrology is Indian Jyotisha that reached Thailand through the Khmer courts. The raw material differs accordingly: saju works with the 60-term cycle built from 10 heavenly stems and 12 earthly branches, while Thai practice works with eight planets, Rahu the lunar node among them.
So does the unit of reading. Saju converts year, month, day and hour into eight characters and reads the five-element relations between them. Thaksa produces no characters; it seats eight houses clockwise starting from the ruling planet of your weekday.
Their centres of gravity differ too. Saju is heavy on time — compatibility and decade-long luck cycles. Thai practice is heavy on the immediate: which colour to wear, which direction favours you, which letters may appear in a name.
Almost always at a date boundary. In saju the year begins at the start of spring in early February, not on 1 January, and the month is cut by the major solar terms, so a January birth legitimately carries last year's pillar.
Then the clock. True solar time and the equation of time can move the hour pillar by a full slot — the longitude correction alone is about 32 minutes for Seoul — and schools disagree about whether a birth after 23:00 rolls into the next day.
Thai practice turns the day at sunrise, around 06:00, and splits Wednesday again at 18:00. Its year turns at Songkran in mid-April, so births from January to early April sit one animal behind the Gregorian count.
Because of this, each tool prints the corrections it applied. A different number usually means a different rule, not a broken calculator.
Name compatibility interleaves the letters of two names, counts strokes, and repeatedly adds neighbouring digits until a single percentage remains. The value matters less than the fact that every step is visible: the same pair always yields the same number, and you can check it by hand.
The Thai rule runs the other way. All 42 Thai consonants and the vowel marks are split into eight groups, one per planet, so the group belonging to the planet in your Kalakini house becomes the letters your name must avoid.
Monday births have the Sun in that house, and the Sun group holds one consonant plus every vowel mark — which is why Monday children are traditionally named with consonants only.
It assembles the parts of a traditional talisman — a crown motif, body glyphs, a border — from a wish and a name, and renders them as a single image you can save or share.
The glyphs are decorative, not ritual. The tool reproduces no school's liturgy and claims no efficacy; the output is closer to a keepsake than to an amulet.
They do not predict anything. No tool here speaks about wealth, health, exams or lifespan, and none is built to inform such a decision. They compute what a traditional rule produces, precisely and repeatably.
They send nothing to a server. Birth dates, names and generated images stay in the browser on your device.
Where schools disagree, the disagreement is exposed rather than hidden — as a toggle for the late-night hour in saju, or as a stated choice of wheel direction in Thaksa.
A birth date and, ideally, a birth time. Without a time, saju leaves the hour pillar out and the Thai chart assumes noon.
The birthplace helps as well. The standard time in force at that place and date, plus its longitude, can shift the hour pillar by one slot, so births outside Korea can be entered with an explicit offset and longitude.
Script matters for the name tools: name compatibility expects Korean names, and the Thai name check expects Thai script, since a romanised spelling cannot be traced back to the original letters.
