- Heavenly Stem Phase and Polarity Lookup Map zero-based Jia through Gui stems to the conventional five phases and alternating yang/yin labels; no personality or causal inference.
- Hour Heavenly Stem Calculator Apply the conventional five-rat hour-stem rule to already established zero-based day-stem and hour-branch indices, not a date/ephemeris solver.
- Month Heavenly Stem Calculator Apply the five-tiger month-stem rule to an already resolved solar-month branch, with Yin=2 as the first month; no lunar-month substitution.
- Sexagenary Cycle Step Calculator Advance a valid sexagenary pair by signed whole cycle steps, preserving stem/branch parity and the one-based ordinal.
- Sexagenary Index to Stem-Branch Converter Decode a one-based sexagenary ordinal to zero-based Jia/Zi stem and branch indices; no date or year assignment.
- Sexagenary Pair Distance Calculator Measure directed and shortest sexagenary-cycle separation between validated one-based pair ordinals; not elapsed calendar years.
- Shichen Double-Hour Calculator Map explicit local clock time to half-open traditional double hours, with Zi spanning 23:00 to 01:00; no solar-time or timezone correction.
