A personal astrology calendar that your calendar app subscribes to

The month grid

The grid borrows the structure of an ordinary calendar. Each day’s content is drawn as bars that span the days they cover and stack into lanes: imported and manual events, multi-day timing windows, transit peaks as compact pills, and a dot on any day with a notebook entry. Each is a labelled layer you can turn off. Behind the bars sits the pressure overlay — on by default, light and moderate days in one tone and high days in another — kept deliberately separate from the bars, so what kind of thing a day holds and how heavy the sky is that day are two questions with two answers. Clicking a bar opens its detail; clicking empty space in a day opens that day: its transits, its events, its notebook, and the local chart angles for that date once an observer location is set. An agenda beside the grid lists the next week, fortnight or month as a plain list.

Nothing is demonstrated with fake data. The grid shows only real imported or manual events plus the transits, windows and notebook days that are actually yours; an empty month is an empty month.

The same items, wherever you plan

Publishing starts with a choice of what to publish. A short setup picks the item types — transit peaks, pressure windows, opportunity windows — and a density: essential, balanced, or everything, each a stated intensity threshold rather than a mood. Saving that choice creates a version, and it is the only event that does; the wording that changes apply when you save is literally true. Every night the horizon rolls forward and the newly covered days are appended. Because each item’s identity is derived from a scan grid snapped to the day lattice, the same item has the same identity on every run, so history is never rewritten and a subscribed calendar updates an event in place instead of duplicating it.

Two routes carry the items out. Google Calendar sync writes them into a dedicated calendar the app creates for the purpose, under a Google scope limited to calendars the app itself created — Cosmic KPI can manage only that calendar, and it holds no scope that reads or changes your own calendars or events. An event whose content changed is patched in place; one that left the published set is removed; one that matches is left alone, and the server reconciles the calendar daily after the roll. The subscription feed is the works-anywhere alternative: a private link that Apple Calendar, Outlook, Google, or anything that reads the standard calendar format pulls on its own schedule. Timed items carry their time zone properly, all-day items fall on the right local date east or west of Greenwich, and an edited item bumps its sequence so clients that honour it take the update. The feed is export only: it never reads or writes the calendars you already keep.

Bringing your own dates in

The other direction is deliberately simpler. You can subscribe the app to a published calendar link — an iCloud calendar’s public address, a Google or Outlook secret address in calendar format — and the server fetches it when you ask it to. It fetches on demand, not on a schedule, and the page says so, because a reader who believes an import refreshes itself would plan around events that stopped arriving. Manual events can be added directly. Either way, your events appear in the grid as their own layer beside the sky’s, and nothing the app publishes ever touches them.

What a date on this calendar means

A transit peak is the instant a contact between a moving planet and one of your natal points is exact, computed from the ephemeris; a pressure window is a span of days whose combined transit intensity stands out from the days around it, with the contacts that produced it attached. Neither is a prediction of an event. They are dates on which the sky’s relationship to your chart has a particular shape, placed next to your own commitments so you can decide what that is worth.

Trying it

The month grid with the transit layer is free. Pro opens the rest: the pressure overlay and day inspector, the multi-day windows, the Google sync, the subscription feed, custom feeds, imported calendars and the PDF report for any timeframe.
