Every New Moon, Full Moon and eclipse lands somewhere in your chart. Most pass quietly. A few hit a sensitive degree at the same moment a slower cycle is already active, and those are the ones people remember. The Lunation Analyzer is built to sort one kind from the other: it takes a single lunation, places it in your chart, and checks it against your solar arcs, outer-planet transits and progressed Moon.
This guide walks through the page as it actually works, from choosing a lunation to reading the timing table. For the background on why lunations matter by house, read New Moon and Full Moon in your houses, and for eclipses specifically, eclipses in the birth chart.
What the tool does
The page is called the Lunation & Eclipse Analyzer. For any New Moon, Full Moon, solar eclipse or lunar eclipse in a chosen year, it:
- draws the lunation on a wheel around your natal chart,
- lists which natal points the lunation Moon aspects,
- checks whether it sets off a natal T-square,
- shows which solar arc and slow transit aspects are already active for you, and whether the lunation touches them,
- reports where your progressed Moon is and what it aspects,
- and, on a second tab, times the fast planets hitting your chart in the days that follow.
What you need
Your birth date, birth time and birth place. The house placement of a lunation depends on your house cusps, so an accurate time helps. See why birth time matters. Without birth data the page can still list the year's lunations, but the analysis needs a chart.
Step by step
- Open the Lunation Analyzer and fill in the Birth Data panel: Name, Day, Month, Year, Hour / Minute and City / Location. Signed-in users with saved charts can use Switch Profile instead.
- Use the Year menu to pick the year you want.
- Open the Lunation period menu. It lists every New Moon, Full Moon, solar eclipse and lunar eclipse of that year, each with its date, sign, degree and the natal house it falls in. Eclipses also show their type, such as Total, Partial or Annular.
- Optionally fill in Current location if you live somewhere other than your birthplace. The lunation chart's angles and houses are then worked out for that place.
- Press Update.
If you do not choose a lunation, the tool opens on the most recent one that has already happened, which is the one currently in effect. The heading then reads something like "Full Moon Analysis" followed by the date.
The Chart tab
The wheel shows your natal chart with the lunation positions around it. The toolbar has the usual Astrolas controls: Display options, Share cards, Export (copy the chart, download a PNG, print or save a PDF), three wheel sizes and a list of bodies you can switch on or off.
On the right, Selected event gives the exact time of the lunation in local time and in UTC, its sign and degree, and its natal house.
Below the wheel the analysis runs in this order:
- A short reading for the lunation in its natal house.
- Lunation to Natal, angles and sensitive points. The natal planets and angles the lunation Moon aspects.
- Natal T-Squares activated by the lunation. If your chart has a T-square and the lunation hard-aspects one of its members within orb, it shows here. Otherwise the page says none was activated.
- Two cross-tier tables. The first lists solar arc to natal pairs where the lunation touches both ends. The second lists transit to natal pairs where it touches the natal end. Columns are Cat., Planet, Aspect, Target and Activates aspect, and each row has a Show more link.
- Solar Arc & Transit aspects activated during the lunation. Your solar arc hard aspects to natal planets (orb about half a degree) and the outer transits from Saturn, Uranus, Neptune, Pluto and Chiron (orb about two degrees). Each row names an event group, such as "Effort / Perseverance" or "Romance / Overspending", with a short description behind Show more. A Setting orb control appears with this table.
- Second Progression Moon. Your progressed Moon's sign and degree, any hard aspects it makes to natal points within one degree, and whether the progressed Sun and Moon are conjunct or opposite.
The Event Timing tab
Switch to Event Timing and press Run. The tool scans the transiting Sun, Moon, Mercury, Venus and Mars against your natal planets, angles, Chiron, Vertex, Lilith and the Node, from the selected lunation onward. The window it scanned is printed above the results.
Results are grouped by date with a count for each day. Each row shows Time, Tr Planet, Aspect, Na Planet, a Background T1 column and the Orb. You can adjust the orb for the fast planets and, separately, a tighter orb for transiting Mars, which the page treats as a first-tier activator against natal planets and key midpoints such as Saturn/Pluto and Jupiter/Venus.
How to read the result
Read from slow to fast. The solar arc and outer transit table tells you what is already building in your life this year. On its own a lunation is a monthly event. It becomes significant when the cross-tier tables show it touching a pair that the slow table has already flagged. That overlap is the main thing to look for.
Next, check the T-square line. A lunation that squares or opposes a natal T-square member tends to show up as pressure to adjust a plan.
Then read the progressed Moon section as the emotional background of the period. The secondary progressions and progressed Moon post explains how to read it.
Only then open Event Timing. Use it to pick out the days when the fast planets hit the same points the slower layers already marked. Those are the likely days for news or decisions.
Tips
- Eclipses deserve a second look months later. Run the same eclipse again when a transit or solar arc reaches its degree.
- Compare a New Moon with the Full Moon two weeks later in the same menu. The Full Moon often shows how the New Moon's start played out.
- If the slow table is empty, the lunation is probably a quiet one for you.
- For the monthly personal cycle, pair this page with the Lunar Return tool.
- Solar arcs are explained in what is solar arc direction.
Questions people ask
Does the tool need my birth time?
It works best with one. The lunation's house and its aspects to your angles depend on it.
Why does it open on a past lunation?
The most recent lunation is the one still in effect until the next one arrives, so it is the most useful default.
Is the Event Timing tab slow?
It scans many small time steps, which is why it waits for you to press Run instead of loading on its own.
Try it
Open /tools/lunation-analyzer, pick the next eclipse from the Lunation period menu and see which of your natal points it reaches. For the day-to-day picture around it, check your transits too.
