    tarot_cardThe meaning of a single Rider-Waite card: upright and reversed, arcanum, suit, links to the image and the page. Looks up by slug (major-00, cups-07) or by Russian name.
    tarot_deckAll 78 cards of the Rider-Waite deck with upright and reversed meanings. Can be limited to a group: major, wands, cups, swords, pentacles.
    tarot_drawDraws cards from the deck without repeats, in upright and reversed positions. With a seed the output is deterministic: the same seed gives the same spread.
    tarot_birth_cardThe personal major arcanum from a birth date: the digits of the date summed and reduced to 1-22. The classic Tarot Birth Card calculation.
    planet_positionsEcliptic longitudes of ten planets for a given moment: sign, degree within the sign, retrograde status. Computed from VSOP87 ephemerides rather than read from tables.
    moon_stateMoon phase, illumination, lunar day, sign and degree for a given moment. Illumination and the lunar day are counted from the real Sun-Moon conjunction, not from the mean synodic formula, which is off by hours and, near midnight, by a whole lunar day.
    aspect_exact_timeFinds the moments when two planets form an exact angle: conjunction, sextile, square, trine or opposition. Steps through positions and refines by bisection, accurate to the minute. The same method yields new moons, full moons and sign ingresses, for which mean formulas are unfit.
    natal_chartA full birth chart for a date, time and place: planetary positions, house cusps, aspects with orbs, the balance of elements and modalities, and major configurations.
