Taijora, published in Chinese as 太極神算, is a browser-based Bazi calculator that puts the arithmetic on the table. You choose solar or lunar calendar, set the birth year, month, day, hour and minute on a scrolling picker, pick the birth city from a map-backed search list, choose male or female, give the profile a label and mark the relationship to you. The engine then converts the recorded local time to true solar time using the birthplace longitude and the astronomical Equation of Time, fixes the year and month pillars at the exact solar-term crossing, applies the early and late Zi-hour rule for the day change, and lays out the four pillars.
The free chart shows the year, month, day and hour stems and branches, the Ten God of each stem, primary, middle and residual hidden stems with their Ten Gods, Nayin elements and a row of auxiliary stars for every pillar. It also prints the true-solar offset and the solar-term timestamps the chart depends on, so every result can be recomputed by hand. A second panel scores the Ten Gods as percentages, gives the weight of wood, fire, earth, metal and water, and names the useful, favourable, idle, hostile and unfavourable elements. A third panel calculates the exact start of the decennial luck cycles from the distance to the nearest solar term, follows the forward or reverse order for yang-male and yin-female or yin-male and yang-female charts, and lists the ten-year pillars with a short reading for the current one.
Charting, Ten Gods, five-element statistics and a basic reading are free. Long-form life reports and multi-stage analyses are unlocked per report or through membership after signing in; the pricing page sits behind the login. Guest charts stay with the current browser session, while signed-in users can keep, switch and delete several profiles from the account area. The FAQ states that unknown birth hours are not silently assumed to be noon, and that the tool will show the year, month and day pillars without inventing an hour pillar.
The interface runs in Traditional Chinese, Simplified Chinese, English, Japanese and Thai. A knowledge base with sections on the Ten Gods, day masters, the five elements, the four pillars and a charting guide is being written, with three Ten-God articles on wealth stars and the Seven Killings already published.
