When does it happen next?
Find the exact dates a planet enters a sign, makes an aspect to another planet, or crosses a point in your birth chart, with every retrograde pass. Each result opens on a chart wheel.
Questions about transits and dates
How do I find out when a transit will happen?
Choose the transiting planet, the aspect and the point in your birth chart, then press Find dates. The tool scans the ephemeris and returns the exact date and time of every hit within the window you choose, in UTC.
Why does the same transit sometimes appear two or three times?
A planet that turns retrograde crosses the same degree up to three times: once going forward, once backward and once forward again. Slow planets like Saturn, Uranus, Neptune and Pluto do this often. The passes are grouped and numbered, because the influence is usually felt across the whole stretch, not only on the exact days.
What is the difference between a transit and an aspect between two planets?
A transit is a planet moving through the sky today making an angle to a fixed point in your birth chart. An aspect between two planets compares two moving planets with each other, for example when Jupiter next squares Saturn. Both are available here.
How accurate are the dates?
Positions are apparent geocentric longitudes from the same ephemeris used across Astroo, solved to within about half a minute. The tool checks the sign and degree of your natal points from your saved birth details, so a wrong birth time or place will shift Ascendant and Midheaven aspects.
Which zodiac does it use?
The tropical zodiac, measured from the March equinox, which is the standard in Western astrology.
Times are UTC and use apparent geocentric longitudes, the same positions as the rest of Astroo. Signs are tropical.
