Dimensions in the total score

Time and city unlock the eighth dimension — Ascendant × Sun. Search fills coordinates and timezone automatically; you can still adjust UTC manually.

Two dates are enough. A city adds the Ascendant; only the city search query goes to Open-Meteo, while birth dates and results stay in your browser.

What the meter actually weighs

Most compatibility pages compare only Sun signs — that is one voice out of seven. The harmony meter listens to the whole choir: the Sun pair for values and life goals, the Moon pair for emotional comfort at home, Venus and Mars crosswise for affection and spark, Mercury for how your conversations go at 1 a.m., life path numbers for direction, lunar birthdays for inner tides, and biorhythm sync for what today specifically feels like between you.

Every dimension shows its own 0–100 bar with a one-line reading, and the dial on top is the weighted sum. The "Today for you two" box is recalculated daily — the pair of you is fixed, but the day is not.

Honest by design

The planetary positions here are real astronomical calculations. The score is a symbolic tradition — a mirror for conversation, never a verdict. Plenty of extraordinary couples score in the middle bands; what they share is usually not the number but the habit of talking about their differences early.

Frequently asked questions

Do I need the birth time or city?

No — the date alone runs seven dimensions. Open the settings panel if you want more: birth time sharpens the Moon, coordinates unlock the Ascendant dimension, and you can switch orbs, sidereal zodiac, and which dimensions count.

Is the score a verdict on our relationship?

No. It is a warm symbolic summary — a prompt for a good conversation, not a measurement of your future. Low bands read as “teachers, not enemies”, never as doom.

Why does part of the result change every day?

The biorhythm dimension compares the two people's physical, emotional and intellectual cycles on the current day. The six birth-based dimensions stay fixed; only “today” moves.
