About Us

Our Mission
Founded in 2026, FunTestHub packs psychology quizzes and traditional fortune-telling culture into lightweight, free tools that take under 3 minutes — no signup required. We believe self-discovery can be fun: whether through MBTI-style personality tests, numerology, or traditional dream interpretation (Zhou Gong's Dream Dictionary).
The vast majority of calculators and self-reflection tools on FunTestHub are completely free to use with zero registration required (supported by advertising), with the exception of optional in-depth paid reports (such as the 2027 Personal Annual In-Depth Report, available as an optional one-time purchase of $9.90 USD).
Our Methodology
Content on this site falls into two categories, each with its own production standard:
- Psychology quizzes (16-type personality, mental age, emotion detector, personality analyzer, etc.): questions draw on publicly documented personality psychology frameworks (such as Jungian types and dimensions related to the Big Five). Interpretations are written in plain language. These are entertainment tools for self-reflection — not clinical diagnoses.
- Traditional fortune-telling (BaZi, Zi Wei Dou Shu, Zhou Gong dream interpretation, angel numbers, Mei Hua oracle, etc.): Calendar and solar-term calculations are built on the open-source library lunar-javascript v1.7.7. The Year Pillar changes at Li Chun and the Month Pillar at each of the twelve Jie solar terms, using their exact astronomical moments. Ten Gods, Day Master strength and luck cycles are implemented following classical texts ("Yuan Hai Zi Ping", "Di Tian Sui", "San Ming Tong Hui"), with Day Master strength informed by Wei Qianli's 1935 "Qian Li Ming Gao". For cultural and entertainment use only.
External Implementation Reference & Benchmark Comparison
For BaZi (Four Pillars) calculations, FunTestHub references the versioned calculation conventions and test cases maintained by Jade Almanac as an external technical reference.
The reference documents calendar, solar-term, and time-conversion conventions used in its calculator. It is intended to support transparency and reproducibility of computational rules, rather than endorse any particular interpretive school or system.
Different BaZi traditions and implementations may use different calculation conventions. FunTestHub therefore documents its own methodology and implementation independently. Below is our benchmark cross-validation across the publicly documented test probes:
⭐ Open Source Benchmarks & Engineering Paper: To ensure total transparency and computational reproducibility, our complete 266-case astronomical edge-case verification test suite is open source on GitHub: fds2003/funtesthub-astronomy-benchmarks, with our in-depth architecture writeup published on DEV.to: Browser Metaphysics Engineering Guide.
| Probe | Birth Moment | Jade Almanac Output | FunTestHub Output | Convention Comparison |
|---|---|---|---|---|
| BASE | 1995-06-20 10:00 | 乙亥 壬午 壬午 乙巳 | 乙亥 壬午 壬午 乙巳 | Exact Match (Quiet control) |
| A1 | 1985-02-10 12:00 | 乙丑 戊寅 庚辰 壬午 | 乙丑 戊寅 庚辰 壬午 | Exact Match (Year turns at Li Chun) |
| B1 | 1990-06-15 23:30 | 庚午 壬午 壬子 庚子 | 庚午 壬午 辛亥 庚子 |
Late-Zi rollover convention difference. Under the late-Zi convention the Day Pillar stays on the birth date (Xin Metal), while the Hour Stem is derived from the next day's Stem via Five Rats formula (Geng Zi). Jade Almanac rolls day at 23:00 (Ren Water); FunTestHub defaults to midnight 00:00 (Xin Metal). Compatible via FunTestHub optional sect: 1.

| C2 | 1988-02-04 23:00 | 戊辰 甲寅 庚寅 丙子 | 戊辰 甲寅 己丑 丙子 | Compound boundary (Li Chun + Zi rollover). Year/month match; day rollover follows B1 logic. |
| D1 | 1995-06-15 09:20 | 乙亥 壬午 丁丑 乙巳 | 乙亥 壬午 丁丑 乙巳 | Exact Match (Standard clock reading) |
