What tradition says
Tradition reads a transit as a climate, not a fact: a planet square your natal Sun would suggest a tension that pushes you to act, a trine an ease to put to use. The nature of the aspect matters, as does the planet’s slowness: the slower it is, the more lasting the theme.
A conditional reading of the real sky, with no prediction: read it with some distance. Why?
How transits are calculated
The tool calculates your birth chart, then the sky of the chosen date, by default today at noon.
The tool calculates your birth chart, then the sky of the chosen date, by default today at noon. It then compares each planet on that date with your natal positions: the ten bodies, plus the rising sign and the Midheaven if your birth time is provided. The orbs are tight: three degrees for the conjunction, square, trine, and opposition, two for the sextile. Aspects are sorted from the most exact to the widest, with a note on whether they are applying or separating. Everything happens in your browser; nothing is placed in the page address.

Frequently asked questions about transits
What is a transit in astrology?
A transit is the current position of a planet, compared with a position in your birth chart. When Saturn forms a conjunction with your natal Sun, it is said to transit your Sun. Tradition reads these meetings as moments of reminder or renewal, never as events.
What orb should be used for a transit?
The tool uses three degrees for the conjunction, square, trine, and opposition, two degrees for the sextile. These orbs are tighter than those of a birth chart, because a transit is judged close to exactness. Other astrologers use wider orbs, with no consensus.
Do you need your birth time for transits?
Not for the ten celestial bodies: the date and place are enough. Without the time, neither the rising sign nor the Midheaven can be determined, so their transits can’t be either. As for the Moon, which moves quickly, its natal position is uncertain if the time is missing.
Do transits say which events are coming?
No. A transit is an astronomical fact, the angle a planet forms today with a point in your chart. What tradition draws from it is a tendency, in the conditional. No transit guarantees that an event occurs, nor rules it out; what you experience depends on your situation.
