All Solar and Lunar eclipses from the last 12 months and the next 12 months are listed automatically. Enter your birth details, choose an eclipse, and see which house it falls in, which natal planet it closely aspects, and whether it triggers your luminaries (Sun/Moon). A classical Hellenistic frame.

Your Eclipse Contacts Are Ready, But This Is Just the Beginning
An eclipse falling on a natal point marks a theme, not a verdict. Reading it alongside your other timing indicators is where it becomes useful.

This eclipse-impact calculator finds all Solar and Lunar eclipses in the last 12 months and the next 12 months using the astronomy-engine library (based on NASA JPL ephemeris data); it then carries your selected eclipse onto your birth chart's house system, planets and sensitive points and interprets it within a classical (Hellenistic) frame.
The method follows the standard practices of the classical tradition:

Common questions about how eclipses affect the birth chart and classical interpretation
When you carry the sign and degree an eclipse occurs at onto your birth chart, you see which house it falls in and which natal planet/sensitive point it closely aspects. In the classical tradition, the house the eclipse falls in is a trigger point where notable events in that house's theme tend to occur over the next ~6 months. If the eclipse is close to the natal Sun/Moon, the effect is much stronger (a luminary trigger). An eclipse does not start a life event on its own; it becomes clear when read in the whole context (transits, profection, solar return).
A solar eclipse occurs at the New Moon (Sun ↔ Moon conjunction) and is read as a trigger that plants the seed of a new cycle: a beginning, an opening, a launch. A lunar eclipse occurs at the Full Moon (Sun ↔ Moon opposition) and is read as a cumulative culmination: reaching a peak, coming to light, a parting. Because the Sun sits on the opposite side in a lunar eclipse, the eclipse is evaluated as an axis: two separate house/planet sets activate at once.
In the classical tradition the main effect period of an eclipse is the 6 months after it. The next eclipse generation renews the cycle. But if the eclipse closely aspects a natal light (Sun/Moon) or sensitive point (ASC/MC), the effect can last for years; especially when re-triggered by a Saturn return, a Jupiter transit, or an active profection year. The effect is most intense within ~2 weeks before and after the eclipse date.
In the classical tradition the Sun and Moon are the “two lights” (luminaries) and represent the chart's life-energy. If an eclipse makes a conjunction/opposition within ±8° to your natal Sun or Moon, this is the strongest kind of trigger: a high likelihood of concrete life events through the year (career change, the start/end of a relationship, relocation, health themes). This tool highlights a luminary trigger as a separate gold card when present. Other planetary aspects are lighter signals.
The tool calculates the eclipse with the house system you choose (default Alcabitius). Whole Sign is the standard house system of the Hellenistic tradition: the entire rising sign is the 1st house, the next sign the 2nd, and so on, each house equals one sign, simple and error-free. Whole Sign is preferred for eclipse interpretation because sign boundaries coincide with house boundaries, so it is clear which area of life the eclipse falls in. In the modern Placidus system an eclipse can land on the boundary between two houses and the interpretation becomes blurred. If you work in the classical (Hellenistic) tradition, Whole Sign is the most suitable.
The aspects an eclipse makes to your natal planets come out correctly even without the time (planets move very little in a day). But to see which house it falls in you need your rising sign, which depends critically on the birth time; a 1-hour difference can shift the Ascendant by about 15°.
If you don't know your time, a temporary workaround: enter 12:00 and read only the eclipse's planetary aspects using a solar-chart approach. A permanent solution: with Rectification Consultation → you can pinpoint your birth time to the minute by working backwards from your life events.
This tool gives you the classical frame; a consultation sets that frame into the real context of your life. With Şira Nur Uysal, using the classical (Hellenistic) method, let's read the chart of the coming 12 months together, the critical dates, the themes and how to prepare.
