BOOJEE Forecast · Transit Timeline
Your life,
against the sky.
Every sign ingress, every retrograde station, every exact transit to your natal chart — computed from a real ephemeris and laid out on one scrollable timeline. Then add the things that actually happened to you, and see what they landed next to.
Birth details
Used to place your natal chart. Stored in this browser only — never sent anywhere. Shared with Today's Forecast, so if you set it there you're already done.
+ Compare a second chart (partner, friend, child — optional)
The same slow transits run against both charts — every exact hit is tagged you or them, so a stretch that pressed on both charts at once reads as exactly that. Stored in this browser only, like everything else.
No birth time? Leave it blank — we use noon UTC and simply omit the Moon, which can move 6° either way in half a day. Everything else is safe to a fraction of a degree. Houses and a rising sign need an exact time and place — add both and we compute your real Ascendant and Midheaven from the actual sky over that location, converted through its true historical timezone. Time with no place (or vice versa) still gets everything else; we never guess the rest, which is how astrology apps quietly make things up.
What this is, and what it isn't
The positions are astronomy. Geocentric longitudes in the tropical zodiac, from the same Swiss-Ephemeris-grade model NASA-derived astronomy-engine ships, computed in your browser. Ingress and station times are solved by bisection to under a second, and cross-checked against the library's own independent solver. If it says Mars entered Scorpio at 04:12 UTC, Mars entered Scorpio at 04:12 UTC.
The meanings are tradition, not measurement. "Friction," "opening," "facing" are the names astrologers have used for these angles for two thousand years. Nothing here is a prediction, and no controlled study supports one. We're not going to dress that up.
Why it's still worth your time. A timeline you didn't author, that you can't retro-fit, is a decent instrument for looking back. You add what happened; the sky was already going to say what it says. When a hard stretch of your life lines up with a slow planet crossing something in your chart three times, you've at minimum found a real structure to hang the memory on — and a reason to stop reading it as personal failure. That's the perspective. Take it as a journal with an unusually rigorous index, not a forecast.
Nothing leaves this device unless you send it. Birth details, life events and a cache of your computed timeline live in localStorage. There is no account, no upload, and no request to us — open your network tab and check. The one deliberate exception is the share link: it packs your settings (and, if you tick the box, your life events) into the URL fragment, which browsers never transmit to a server — the data travels only inside the link you choose to send, to the person you send it to.
