Public beta · Android & web · Free while it lasts

Some hours are better than others.

WhenStars works out the planetary hours for the place you are standing, from a real ephemeris, and says in plain English what each one is fit for.

Today at Greenwich · 51° 28′ N, 0° 00′

Twelve unequal hours of day, and twelve of night.

The daylight is divided into twelve and so is the darkness, so in summer an hour of day runs long and an hour of night runs short.

What it is

Not a horoscope. A timetable.

Every day is cut into planetary hours from true sunrise and sunset at your coordinates. Each one is weighed against your own birth chart and laid out as a day you can read at a glance.

Positions
Planets come from the JPL DE440s ephemeris and are checked against Swiss Ephemeris to within a hundredth of a degree. Placidus houses, tropical zodiac, the traditional seven.
Method
Dignity, sect and rulership follow seventeenth-century practice rather than a modern shorthand. When the engine calls an hour difficult, you can open the reasoning and read why.
Words
Over three thousand passages, fixed in place. The same sky gets the same words every time, it works with no signal, and nothing is being made up at the moment you read it.
Scope
Seven parts of life scored apart from one another. A morning can be good for a hard conversation and poor for signing anything, and the app will say so.

Where it stands

A beta, and here is what is missing.

Everything above works today: the chart, the scoring and the calendar all do what this page says they do. What follows is what they do not do yet, because finding out for yourself is a worse way to learn it.

Not yet

There is nothing to buy

Nothing can be bought while the beta runs. A new account gets thirty days of the whole calendar for nothing. There will be a price once the stores are ready, and no one will be charged without saying yes first.

Next

No iPhone app

Android and the browser for now. iOS wants an Apple developer account and a review cycle, and it follows once the beta settles. The web version works perfectly well on an iPhone meanwhile, and if you would rather be told when the real one lands, say so.

Built, not run

English only

German, Spanish, Ukrainian and Slovak are the ones I want next. The machinery for translating the library exists and has deliberately not been run, because three thousand passages of astrological English need a speaker of each language to read them before they ship, and that takes far longer than the translating does.

Planned

No sign in with Google or Apple

An email address and a password for now. Nothing is handed to anyone either way, which is the part that actually matters.

Open question

The hours are quieter than they should be

The ruler of each planetary hour does not yet feed the score, so one hour differs from the next by less than a traditional astrologer would expect. Day readings are unaffected. This is a matter of doctrine, and it is being settled rather than patched.

Designed

More technique is owed

Time-lord periods, mutual reception, the rest of accidental dignity, and transit-to-transit aspects. What is there is right; there is simply more of it owed.

If something looks wrong, it may well be. Write and tell me, and I will fix it.
