✨ n8n · just for fun

The sky of your birth night.

Enter a date and a place. An n8n workflow works out what the sky looked like that night and draws it as a poster: stars, constellations, planets and moon, plus the weather back then and a short AI portrait.

🔒 Privacy: only the date, time, first name, place (rounded to 0.1°) and the result are stored. No IP address, no cookies. Everything is deleted automatically after 30 days, and you can delete it yourself with one click before that. Privacy policy

How it works

  1. Find the placeThe city is turned into coordinates and a time zone with Open-Meteo.
  2. Query in parallelWeather back then, on your last birthday and a forecast, plus «on this day» from Wikipedia and the star catalogue.
  3. Compute the skyA code node calculates stars, constellations, planets, the moon and the numbers about your day, no astrology.
  4. Write the portraitAn AI turns the facts into a short portrait of your day.

Without a time I use 22:00 local time. Weather is available from 1940, the sky from 1900. It is astronomy, not a horoscope.
