Caldera Astro

Read each day through the Chaldean lens. Planetary hours, sacred calendar, daily oracle, and alchemy teachings rooted in Hermetic tradition.

Each day has a ruler. Each hour belongs to a planet. The week itself traces the Chaldean order — Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon — an ancient sequence embedded in every language that names the days.

Caldera reads the sky the way it was read for two thousand years.

DAILY ORACLE Every day, Caldera computes the ruling planet using the Chaldean system and assembles a synthesis of the day's celestial factors: planet, lunar phase, moon sign, active fixed stars, and sky positions. Not a horoscope. A map.

PLANETARY HOURS & CHALDEAN ORDER The seven classical planets govern the hours of the day in the Chaldean sequence, tracked in real time. Toggle the Chaldean Order to re-map the week to its true planetary rulers — the system behind alchemy, the Kabbalistic Tree of Life, and Agrippa's Occult Philosophy (1531).

ALCHEMY TEACHINGS Each day, a teaching drawn from the alchemical tradition — the Magnum Opus, the Rosarium Philosophorum, the seven planetary metals. The teaching shifts with the ruling planet, guiding inner work through Nigredo, Albedo, Citrinitas, and Rubedo.

SACRED CALENDAR Holy days, lunar festivals, eclipses, and sacred observances — month by month, drawn from the Western esoteric calendar. The moon's phase, sign, and void-of-course windows are tracked daily.

SKY NOW Real-time positions for the Sun, Moon, and classical planets. Retrograde alerts. Eclipse warnings. Fixed star conjunctions when active.

BIRTH CHART READINGS Hand-written personal natal chart readings, delivered within the app within seven days.

WIDGETS & APPLE WATCH Home screen and lock screen widgets show the day's ruling planet, planetary hour, and moon phase. The Apple Watch face keeps the Chaldean clock on your wrist.

CALDERA PLUS Unlock the full Sacred Calendar beyond today, the complete Daily Oracle, alchemy teachings, an ad-free experience, and a member natal chart reading.

For those who work with the planetary week not as metaphor, but as method.
