Is this investment advice?

No. The checker reads the sky for the timing of an action you have already decided on. Whether to buy is a question for your numbers and your adviser.

Friday is Venus's day in the classical week, and Venus rules pleasure, value and the things we buy. The Picatrix day-ruler doctrine assigns each day's affairs to its planet.

How far ahead does the list for buying or investing go?

Two weeks. The list is recomputed every hour from the real sky, so it is always the next two weeks from now. Bookmark the page.

What if there is no clear window?

Sometimes the sky is busy for a stretch and the next two weeks have none. Then the window checker will show you the least bad part of a day, and the answer is to go with your eyes open or wait.

What time zone are these in?

Central time first, with UTC under it. The embedded checker on this page shows every window in your own time.

What the sky weighs

The rules for this

Buying is a beginning you have to live with, so the engine favours a waxing Moon and the Moon in a fixed sign for things meant to last, and Venus's day Friday and Jupiter's day Thursday. The Moon applying to Venus is the classical signature for a good purchase.

Against it: the void-of-course Moon (the thing disappoints or needs returning), Mercury retrograde for anything with a contract or a warranty, and the Moon applying to Saturn (the price is wrong) or Mars (haste).

For anything with paperwork, the signing rules apply too. Check both.

Every rule that can fire, with its source

-3 The Moon makes no more contacts before leaving its sign. Matters started now tend to drift — nothing comes of them.William Lilly, Christian Astrology (1647); concept from Sahl ibn Bishr, On Elections, trans. Benjamin Dykes (2008)
-2 Mercury retrograde: paperwork, agreements, and messages misfire more easily. Review is favored; new signatures are not.Sahl ibn Bishr, On Elections, trans. Benjamin Dykes (2008); Hephaistio of Thebes, Apotelesmatics Book III, trans. Benjamin Dykes (2013)
+2 The Moon is increasing in light — the classical window for beginnings meant to grow.Dorotheus of Sidon, Carmen Astrologicum Book V, trans. Benjamin Dykes (2017)
+1 Moon in a fixed sign: what you start now tends to stick. Choose it for permanence, avoid it for anything you may want to unwind.Dorotheus of Sidon, Carmen Astrologicum Book V, trans. Benjamin Dykes (2017)
+2 The Moon's next contact is a friendly one to a benefic — the matter lands softly.Sahl ibn Bishr, On Elections, trans. Benjamin Dykes (2008)
-2 The Moon's next contact is a hard one to a malefic — friction arrives before the finish line.Sahl ibn Bishr, On Elections, trans. Benjamin Dykes (2008)
-1 Venus retrograde: valuations and relationships are under review. Renegotiate old terms; don't set new ones.Hephaistio of Thebes, Apotelesmatics Book III, trans. Benjamin Dykes (2013)
+1 Today's planetary ruler favors this kind of action (Sun-Sunday: visibility; Moon-Monday: home and gathering; Mars-Tuesday: contest and effort; Mercury-Wednesday: contracts and messages; Jupiter-Thursday: growth and asking; Venus-Friday: partnership; Saturn-Saturday: endings and structure).Picatrix (Ghayat al-Hakim) Book I, trans. Dan Attrell & David Porreca (2019)

For a business

How owners use it

Equipment, software contracts, a vehicle, inventory for the season, the building. A business purchase is usually also a contract, so the engine's signing rules are worth reading alongside these. Money decisions still belong on the numbers; the sky only picks the day.

Rhythm for Business plans the quarter around these windows: the new moon as the start of a cycle, the full moon as its review, and the clear windows for the decisions that matter. Open Rhythm for Business.
