The reading names the aspects, sign ingresses, lunations and retrograde stations driving it and reads each into the whole-sign houses of that sign, so every sign gets different content rather than one blurb reused twelve times. Alongside the column come overview, love, career, health, finance and advice, the active transits, Moon sign and phase, an energy rating, lucky number and color, and compatible signs. No language model is involved, so a given sign and date always returns the same text and a piece scheduled months ahead is the piece that runs. Content rolls over at midnight, by default UTC. Pass date for editorial scheduling, or timezone to roll over on a local clock. Available in eight languages. Daily horoscope API, zodiac forecast, sun sign horoscope, astrology prediction.

Calculated on tropical longitudes. The Moon is excluded because it forms hundreds of aspects a month and belongs in a daily view rather than a monthly one. Omit year and month to get the month in progress, so a published calendar stays current without a redeploy.

The composite chart represents the relationship as a single entity, showing its core identity, emotional bond, communication style, and growth direction.

A crossing from south to north is an ascending node passage, north to south a descending one. These are the instants a body sits exactly on the ecliptic rather than merely near it, which is what makes an eclipse possible when a lunar crossing coincides with a New or Full Moon, and what practitioners use for node-based timing. Returns the exact date and time in your timezone with the tropical longitude and sign. The Sun and the lunar nodes are excluded because they lie on the plane by definition and so have no nodes of their own. Essential for eclipse-season work, node timing, and astronomical calendars. Ecliptic crossing API, planetary node passage, ascending and descending nodes. Verified against NASA JPL Horizons.

A parallel is two bodies at the same declination and reads much like a conjunction; a contraparallel is equal and opposite declinations and reads much like an opposition. Neither depends on zodiacal distance, so they surface connections an aspect table cannot show, which is why traditional and modern practitioners read them alongside aspects. Declinations are geocentric, matching what an ephemeris publishes. Returns the exact date and time of closest approach in your timezone with both declinations. The Moon is excluded because its declination swings the full range every month and would bury the slow pairs. Omit year and month to get the month in progress, so a published calendar stays current without a redeploy. Essential for declination work, out-of-bounds tracking, monthly forecast copy, and electional timing. Monthly parallel calendar API, declination aspects, contraparallel ephemeris.
