When is the sky like this?

Trismea sweeps a date range and tells you when the chart looks the way you need it to — then keeps the record of what you did under it, with that sky frozen alongside. The other electional engines stop at the date.

A working instrument for traditional astrology and ceremonial practice. Built on JPL DE440, the ephemeris NASA uses for spacecraft navigation. Every correspondence names the book it came from.

Free for a week. Create an account and the whole console opens — charts, electional search, rites, the magical record, the workshop and the cited corpus — for seven days.

No credit card, and nothing to cancel — when the week is up the account simply becomes read-only, and everything you wrote during it stays yours to read and to export.
