A detailed timing calculation does more than look up a Sun sign or display one daily transit. It resolves local time, astronomical positions, traditional calendar boundaries, personal context, and many rule interactions.
The large number of checks is less important than traceability: users should be able to see which factors contributed and what a score does not mean.
From time and place to a frame
Pull Future first normalizes the date, time zone, coordinates, and requested time scale. It then calculates the relevant astronomical and calendrical state for that frame.
Short-lived factors need exact boundaries; long-lived periods need consistent hierarchy and stable identifiers.
Rules become evidence
Individual rules can add support, caution, confidence, and explanatory text. Conflicts are expected, so aggregation should preserve the evidence rather than hide it behind one opaque number.
A useful narrative is generated from validated structured data and must never expose raw provider errors or malformed output.
What calculation cannot provide
Computation can apply a defined system consistently; it cannot prove a future event, substitute for professional judgment, or remove uncertainty.
Pull Future is an educational planning tool. Its strongest value is organized context, transparent timing boundaries, and repeatable comparison.
