What the transit calculator shows
The tool calculates the positions of the transiting planets on the chosen date and their aspects (conjunction, sextile, square, trine, opposition) to the planets in your natal chart. The bi-wheel shows your natal chart inside and the transits outside.
How to read transits
Pay attention to applying aspects of the slow planets - they are approaching exactness and have the strongest effect. The orb shows how close the aspect is to exact.
Transits for today and any date
By default the transits for today are shown, but you can pick any date - past or future - to plan important events or review past ones.
What a transit is and how it works
A transit is an aspect between a planet in today's sky and a point in your natal chart. The natal chart never changes; the sky above it does, and every contact it makes with a natal point switches the matching theme on for a while.
The calculator takes your chart, computes the planetary positions for the chosen date and lists every aspect between them with its exact orb. For each aspect you see whether it is applying or already separating: the first means the peak is ahead, the second that it has passed.
- •Transits for today or for any date in the past or the future
- •The orb and direction of every aspect, applying or separating
- •Aspects to the planets, angles and house cusps of the natal chart
How long a transit lasts
Duration follows the speed of the planet. The Moon completes an aspect in hours, the Sun, Mercury and Venus in two or three days, Mars in one to two weeks. Jupiter and Saturn hold a theme for months, Uranus, Neptune and Pluto for years.
Slow planets often pass a point three times: direct, retrograde, then direct again. The first pass raises the question, the second reviews it, the third closes it. That is why something that began in spring frequently resolves only a year later, and that rhythm is normal rather than a glitch.
- •Moon: hours, visible as mood shifts and small events
- •Sun, Mercury, Venus: days, they set the tone of a week
- •Mars: up to two weeks, activity and conflict
- •Jupiter and Saturn: months, a change of stage
- •Uranus, Neptune, Pluto: years, a change in the structure of a life
Which transits to read first
Start with slow planet transits to the Sun, the Moon, the Ascendant and the Midheaven. Those describe the large periods. Moon transits are useful for day to day planning, but drawing life conclusions from them is a mistake.
Precision matters more than the aspect name. A transit within one degree is felt clearly; at five degrees it usually stays in the background. When two or three exact transits converge on the same week, that is the period worth looking at closely.
Transits, progressions and directions
Transits show external circumstances and the timing when a theme switches on. Progressions describe inner maturation, the way a person changes regardless of events. Directions give precise dates for key turning points and work in a narrower window than transits.
In practice progressions and directions show what has ripened, transits show when it surfaces. When all three methods point at the same period, the event is almost always noticeable. When a transit is strong but the progressions are silent, it usually turns out to be an external circumstance without lasting consequences.
Common mistakes when reading transits
The first mistake is reading a transit without the natal chart. Saturn in Pisces on its own means nothing specific; the meaning appears once you see which house it entered and what it aspects in your chart in particular.
The second is expecting the event exactly on the day the aspect is exact. Slow planets work through a wide window and the decision often ripens weeks before the peak. The third is watching only the hard aspects: an unused Jupiter trine passes as quietly as any other missed opportunity.
Planning with transits
Look three to six months ahead and write down the dates when aspects become exact. That shows which weeks suit starting something new and which are better spent finishing what is already running without taking on more.
A saved chart is filled in automatically, so checking new dates takes seconds. For picking a specific day for a specific task there is a separate date selection tool that weighs both the transits and the position of the Moon.
