Backtest

Test it on a day you already lived.

Remember a really good day, or a really tense one? See what the sky was doing—and say whether it matched.

One real backtest: the founder’s own chart on 20 July 2026. Nothing typed in, no day chosen by hand.
Date to backtest (past dates only)
Date of birth
24h

Optional—without it we can’t place your rising sign and the parts of your chart, so the scores are a little less precise.

Type your birth city, then pick it from the list.

Your birth data is only used to build your chart—never shared.

Past dates are free, forever. One day is a taste; three or four show you how the astrology engine reads your life.
