TONIGHT'S SKY
宵の空
Yukari Sensei
Write what is on your mind and press the button. The sky of this exact moment is frozen beside your words, so you can sit with both.
Your words stay on this screen. They are not saved or sent anywhere.

A map of the sky as it stands right now, offered as a quiet starting point for reflection. The stars do not decide your path.

The wheel moves with the sky and refreshes every half minute.

How the sky is calculated, and how far to trust it
Where the planets are

The site works out the positions of the Sun, Moon and planets itself, in your browser. We checked it against NASA data: the Moon and Sun against NASA's catalogue of 66 solar eclipses (2001 to 2030), and every planet from Mercury to Pluto against NASA JPL Horizons on 17 dates between 1950 and 2030. The planets agreed to within 0.1 degrees at worst, and usually within 0.02. That is more than enough to place a planet in the right sign. The one exception is a planet within a few hours of changing sign. The rising sign also depends on the exact birth time and place.

The Moon

The Moon moves about 13 degrees a day. Without a birth time we use noon, so the Moon can be off by up to about 6 degrees. Add a birth time for a better Moon.

Sign edges

If a planet sits right on the edge of a sign, a small difference in birth time or time zone can tip it into the next sign.

The angles between planets

Links use the classic angles of 0, 60, 90, 120 and 180 degrees, with a small allowance either side (4 to 8 degrees, depending on the angle). Astrologers differ a little on these allowances. Ours are a common middle.

What it cannot tell you

The meanings come from astrological tradition. They are a prompt for reflection, not a prediction, and nothing here confirms how a relationship or a day will go. The decisions are always yours.
