The birth card, its partner card, and the name card, across the 22 major arcana.
The birth card is the Angeles Arrien reduction: month plus day plus the FULL YEAR, digit-summed until it lands in 0-21. The partner card is the single-digit reduction of that, which is what pairs a high trump with a low one. The name card is the Pythagorean name total reduced the same way.

The moment to calculate for, ISO 8601. ALWAYS include an offset or a trailing Z - a value with no zone is read as Asia/Kolkata (UTC+05:30), not UTC, and can return the previous day's result with a 200. '2026-09-01T06:00:00Z' and '2026-09-01 06:00:00' are different instants and give different answers.
