Computing planetary positions…
Read it the way you would read a natal chart - 0° Aries on the left, the signs running counter-clockwise from there. Each planet sits at its true degree, and an ℞ marks the ones moving retrograde.

What “retrograde” actually means
Planets never reverse - it is an optical effect. Earth travels its own orbit at a different speed, and when it overtakes an outer planet (or falls behind an inner one), that planet appears to back up through the zodiac for a couple of months. A roadside post “moves backwards” the same way when you overtake a car.
The astrological reading is far milder than the reputation. Everything tradition attaches to a retrograde starts from a single prefix - re-: revisit, revise, rework, reread. Nothing breaks; the same matter simply comes round a second time. The full picture is on the retrograde planets page, and the most famous case has its own: Mercury retrograde.
How this is computed
Positions come from Swiss Ephemeris, the ephemeris library behind most professional astrology software. Accuracy is a fraction of an arc minute - these are the same numbers paid programs show.
Nobody is asked for coordinates here, and none are needed: a planet's zodiacal longitude is the same number in Lima as it is in Lisbon. The moment itself is taken in UTC, at the second the page loads. Place enters only with houses and the ascendant - that is the natal chart.
Frequently asked questions
How often does this update?
On every page load. The Moon moves about half a degree per hour, so its position visibly changes even within a single day.
Why are planets drawn at different depths?
Readability only: when several planets cluster in one sign, a single ring would blur them into one spot. The true degree is unchanged and listed in the table.
Is this the same as my natal chart?
No, and the difference is the whole point of both pages. This one shows a single sky that everybody on Earth shares at this second. A natal chart freezes the sky at the moment you were born, which is why it needs a date, a time and a place.
Where do I see what it means for me personally?
A transit only means something once it is laid over your own chart, and that reading lives in the app. The place to begin is a natal chart built from your date.
Planetary positions are astronomy, verifiable to the arc minute. Their interpretation is a symbolic system for self-reflection, not science.
And what it means for you
Everyone gets the same sky; nobody gets the same chart. Where today’s planets fall in yours is what turns a transit from a fact into something personal, and that is the part Luna reads aloud.
