Before you begin
What can I do on Coeluna?
Calculate your full birth chart, read today's horoscope for your sign, compare two charts for compatibility, draw tarot cards — including a card of the day — and learn astrology from a plain-language library. Everything is free.
How long does a birth chart take?
About thirty seconds. Enter your birth date, time and city and your chart appears right away, with every placement explained.
How is the daily horoscope written?
It's computed live from the real sky: the Moon's phase and sign, the planets moving through your sign and the day's tightest aspects. Add your birth chart for transits made just for you.
Is my birth data private?
Your birth details never leave your device: every calculation runs in your browser. We don't store, sell or share your data, and there's no account to create.
How accurate are the charts?
Very accurate. In 100 published comparisons with NASA/JPL data, every planet was within 0.03° (under 2 arcminutes), far too small to change a sign. Houses use Placidus, with equal houses near the poles. Calculator accuracy →
What if I don't know my exact birth time?
Without a time, Coeluna estimates planet positions at local noon and hides Rising, Midheaven and houses. The Moon may have two possible signs; other planets can also be uncertain near sign boundaries.
What are streaks and badges?
Reveal the tarot card of the day to fill a 29-day lunar streak, collect all 22 Major Arcana and earn badges as you learn. It all lives in My Sky — no sign-up, saved on your device.
Your chart is waiting in the sky.
It takes about thirty seconds. It might explain a few things.
