Free Astrology and Esoteric Tools

Six free astrology and esoteric tools, with no account and no sign-up: a sacred calendar with today's moon phase, sign and lunar mansion; a natal chart calculator; your Saturn return dates; the monthly Chrism Fast window for your Sun sign; and two self-reflection quizzes, the Gnosis Score and the initiation paths.

Four of them compute real positions of the Moon and planets from an astronomical ephemeris. The natal chart, Saturn return and Chrism Fast calculations run in your browser. The other two ask questions and hand you a mirror. None of it predicts.

The Discourse on the Eighth and Ninth, a Hermetic text found at Nag Hammadi, already times a sacred act by the sky; these tools read the heavens the same way, as a clock for inner work.

Questions

Questions people ask

Are these astrology tools free?

Yes. Every instrument here is free and needs no account or payment. The Chrism Fast calendar offers an optional sign-in for email reminders and a calendar feed; the calculator works without it.

How are the dates and positions computed?

From an astronomical ephemeris, the open-source astronomy-engine library. The Sacred Calendar is computed on the server and refreshed every hour; the natal chart, Saturn return and Chrism Fast calculations run in your browser.

Do these tools predict the future?

No. They give positions, dates and windows of time, and the two quizzes reflect your own answers back to you. Nothing here forecasts events.

These are contemplative instruments — not prediction, and not medical advice. The sky sets the hour; what you do with it is the work.
