Make a custom star map poster of the real night sky over any place, on any date: the night you met, a birth or a wedding. Every star, planet and the Moon are shown where they really were, ready to print.

How to make a star map by date and place

  1. Choose a place and a date and time.
  2. Pick a design and the details: constellations, the Milky Way, the planets and the Moon.
  3. Add your own text.
  4. Save the poster as PNG, PDF or SVG at full print resolution.

Frequently asked questions

How accurate is the star map?

Stars come from ESA's Hipparcos catalogue, moved to your date; the Sun, the Moon and the planets are computed with Astronomy Engine, accurate to well under an arcminute.

Does it show the Moon phase?

Yes, the Moon is drawn in its real phase for that night, lit from the side where the Sun is.

What does the circle show?

The whole sky above the place: the edge is the horizon and the centre is straight up.

Can I print it large?

Yes. PDF and SVG are vector files, so stars, lines and letters stay sharp at any size.

Is it free?

Yes, free and without sign-up.

The whole sky above you, horizon at the edge, north up and east on the left, as when you look up. Stereographic keeps the shapes of constellations true; equidistant keeps distances from the zenith even.
