The Aspect Calendar is a timing engine: pick a set of points, a set of aspects and a comparison mode, and it searches a span of time for every moment those points form those aspects — showing both the in-orb windows leading up to each hit and the exact perfecting moments themselves.
Opening it
Tools → Aspect Calendar… — a Pro feature. From the Dashboard, opening it before any profile is loaded doesn't do nothing — it falls back to a transit-only search (sky-to-sky) automatically, so the tool is useful even before you've picked a subject. From the Expanded Chart View, a profile must already be open; the two natal-dependent comparison modes stay disabled either way until one is.
Three comparison modes
- Tr → Tr — Transit → Transit: sky-to-sky, every pair among your selected points aspecting each other as they move.
- Tr → Na — Transit → Natal: transiting points aspecting your natal chart's fixed positions.
- Pr → Na — Natal → Progressed: secondary-progressed positions (a day of ephemeris motion standing in for a year of life) aspecting the natal chart.
Tr→Na and Pr→Na need a natal chart loaded — they're greyed out until one is.
Choosing the search
The toolbar has four groups. Period is a fixed span from the anchor moment — 30 days, 90 days, 6 months or 12 months. Planets & Angles is 12 bodies (Sun through Pluto, plus Chiron and the North Node) and the two natal angles, Ascendant and Midheaven — angles only ever appear on the "to" side of a pair, since they can't transit or progress. Aspects toggles which of the six classical aspects to search for, each with its own built-in orb: conjunction (±8°), sextile (±5°), square (±7°), trine (±7°), opposition (±8°) and quincunx (±3°). The default search covers Jupiter through Pluto against the five major aspects (quincunx off) over the next 12 months.
The Aspect Finder — Graph and Grid
The Finder tab has two views of the same result. Graph plots one orb-distance curve per pair-aspect across the window — a "blade" that dips toward zero as the aspect comes into then out of orb, coloured by aspect type; hovering one dims the rest and brightens it for a clean read in a crowded chart. Grid turns the same result into a heat table — one row per pair-aspect, one column per month, shaded by how tight the orb gets that month with a marker on any month containing an exact hit.
Graph view — each blade is one pair-aspect dipping toward zero orb as it comes into range; the flattest dips near the top mark the exact hits.
Grid view — the same search result as a heat table; a filled marker on a bar means that month contains an exact hit.
The Exacts tab
Every moment a selected aspect actually perfects, grouped by pair and sorted by date — the exact date and local time, the degree and sign it perfects at, whether the faster body is applying or separating, and a ℞ flag if it's retrograde at the hit. Clicking any row, or the footer's Add to timeline button (which jumps to the tightest exact in the current results), closes the dialog and moves the chart's transit timeline straight to that moment — the same jump-to-moment handoff used by Movements of the Moon.
One row per perfecting moment, grouped by pair and sorted by date, with the applying/separating state and any retrograde flag on the right.
Exporting
The footer's Export CSV button writes every exact in the current results to a CSV file — one row per hit, with the subject, comparison mode, date window and timezone recorded in the header block above the table.
What's next
The Aspect Calendar tells you exactly when a contact perfects; the Graphic Ephemeris shows the same kind of contacts as a continuous, scrubbable picture across years at once: Graphic Ephemeris →
