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 (it isn't part of Extended). You can also reach it from the Aspect Calendar → link on the Transits Today dashboard card. 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 — Natal → Transit: 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. Compare picks the mode above. Period is a span from the anchor moment — 1d, 7d, 30d, 90d, 6m or 12m. Planets & Angles holds twelve core chips (Sun through Pluto, Chiron and the North Node) and the two natal angles, Ascendant and Midheaven, on their own row — angles only ever appear on the "to" side of a pair, so they're disabled in Tr → Tr. Aspects holds six core chips: conjunction, sextile, square, trine, opposition and quincunx. The default search covers Jupiter through Pluto against the five major aspects over the next 12 months.
Orbs
Orbs come from your own Settings → Aspects transit orbs, so the calendar agrees with the rest of the app. Out of the box they are conjunction and opposition ±4°, trine ±3°, square and sextile ±2.5°, quincunx ±1.5° — a little wider when the Sun or Moon is involved. Hover an aspect chip to see its orb, e.g. Conjunction ±4° (±5° with Sun/Moon).
More bodies: the ⋮ menu
New in 3.1: the last chip on the planets row, ⋮, opens More bodies — anything in the Planetary Bodies catalogue, whether or not it's switched on for the wheel. Submenus follow the catalogue's tabs: Asteroids, Fictitious Points, Arabic Parts and Fixed Stars. Tick up to 12 extra bodies; each adds its own chip (wrapping to a second row) and joins the search. The top line counts them — 3 of 12 extra bodies selected.
- Arabic Parts, the Vertex and the Prenatal Syzygy work as moving bodies too: in transit they're recalculated for each moment at the birthplace, so they need a natal profile loaded.
- Transiting Lots and the Vertex move fast — round the zodiac every day — so while one is selected in Tr → Tr or Tr → Na the period is limited to 30 days (90d, 6m and 12m are disabled), and the Exacts tab shows the first hits per pair with a note that the CSV lists them all.
- Fixed stars are always targets: the moving bodies aspect them, in every mode including Tr → Tr.
The ⋮ menu adds asteroids, fictitious points, Arabic Parts and fixed stars — up to 12 extra bodies.
More aspects, including parallels
The ⋮ chip at the end of the aspects row adds every other aspect type, grouped by kind — Minor Aspects (semi-square, sesquiquadrate, semi-sextile, quintile, bi-quintile, septile, novile), Harmonic & Septenary (decile, tredecile, quindecile, bi-septile, tri-septile, bi-novile, vigintile, undecile) and Declination (Parallels). Each entry shows its angle and orb. Parallel and Contra-Parallel are searched on declination rather than longitude: equal declination, or equal and opposite.
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.
The Calendar tab
New in v2.0.0: a third tab alongside Aspect Finder and Exacts, reading the same search result as a plain day-by-day list rather than a graph or a table of only the exact hits. Every day in the selected period gets its own row group — weekday, full date, and how many aspects are in orb that day — followed by one row per aspect that's in orb, tightest first, each tagged Applying, Separating or Exact with its current orb in degrees. Orb is sampled at local noon each day, so a fast-moving contact that's only in orb for part of a day may show up with a slightly different reading than the Finder's continuous curve. A day with nothing in orb still gets its header, reading plainly "no aspects in orb," so the calendar reads as a continuous day-by-day record rather than skipping quiet stretches.
This view works with whichever comparison mode you have selected — Tr → Tr, Tr → Na or Pr → Na — so it's just as much a transit-to-transit or progressed calendar as it is the Transit-against-Natal reading it's most often used for.
Two consecutive days from a 12-month Tr→Tr search — Neptune sextile Pluto stays inside 0.1° both days, while Jupiter trine Saturn flips from Applying to Separating overnight.
Exporting
The footer's Export CSV button writes a different shape of file depending on which tab
is active. On Finder or Exacts, it writes every exact in the current
results — one row per hit, with the subject, comparison mode, date window and timezone recorded in the
header block above the table. On Calendar, new in v2.0.0, it instead writes the full
day-by-day listing — one row per in-orb aspect per day across the entire searched period — with columns
for date, weekday, both points and sides, the aspect, the orb, and the Applying/Separating/Exact state;
the header block adds a line noting orb is measured at local noon each day. The default filename marks
which shape you're getting: an Exacts export is named plainly after the subject, while a Calendar export
is suffixed "- Aspect Calendar Daily -" and the date it was generated.
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 →
