Aspect Search
You're trying to pin down the exact date a transiting planet lines up with something — a point in your chart, or just a specific degree of the zodiac. Aspect Search runs that search for you: set the transiting body, the aspect, the orb, and the target, and it returns every date in your chosen range where the aspect perfects.How it works ↓

Fill in the details above and compute to see your result here.
Find every date a transiting planet forms an exact aspect to a natal point or a fixed zodiacal degree, across any date range.
You can target a natal point or a fixed degree
The target is either a point in your birth chart — your natal Sun, your Ascendant, any planet or angle you have data for — or a fixed zodiacal degree you type in yourself, like 15° Taurus.
Both modes search the same way and return the same kind of result: a list of dates. What changes is what the transiting planet is lining up with.
Fixed-degree mode works without a birth chart
Search a fixed degree and the tool needs nothing from you beyond the degree itself, the aspect, and the date range — no birth data required. That makes it usable for questions that aren't about you specifically, like "when does Jupiter next hit 0° Aries."
Switch the target to a natal point and the search becomes personal: it needs your own chart to know where that point sits before it can look for a transit to it. This is the one branch of the tool where the result depends on whose chart you're running it against.
Five aspects, one search
The tool supports the five classical Ptolemaic aspects: conjunction (0°), sextile (60°), square (90°), trine (120°), and opposition (180°). Each is a straightforward angular relationship between the transiting body's longitude and the target's.
Pick one aspect per search. If you want to check a planet's full aspect pattern to a target, run the search again with a different aspect selected.
The orb sets how much slack you allow
An orb is the allowed margin of error around the exact angle — the tool ships with a small default orb, and you can widen or narrow it. A tighter orb returns fewer, more exact dates; a wider one catches the approach and separation around the exact moment too.
If you're not sure what to use, start with the default and widen it only if you're not seeing the date you expected.
Results are ordered by date, not by tightness
Each row in the result is a date the aspect perfects — the point where the transiting body's position lands within orb of the target degree. Rows run chronologically across your date range, so you can scan forward through a year or decade in order.
For a fast-moving body like the Moon, expect the same aspect to perfect repeatedly across even a short range. For an outer planet, one exact date might be all you get for years.
Frequently Asked Questions
What does "exact" mean for an aspect date?
It's the date the transiting body's position lands within your chosen orb of the target degree — described here as the date the aspect perfects, since the precise moment depends on the orb you set.
Do I need my birth chart to use Aspect Search?
Only if your target is a natal point. Search a fixed zodiacal degree instead and no birth data is required.
What orb should I start with?
Start with the tool's default orb, which is intentionally small, and widen it only if the date you expect isn't showing up in your results.
