Birth moon lookup

What moon phase was on my birthday?

Pick your birth date and see the exact moon that hung over that night — computed from real astronomy, not a stock illustration. When you like what you see, the same engine renders it as a birthday moon phase poster you can download and print.

A birthday gift made of one night

Their real sky, not a template

Date, hour and city set the moon's illumination and the rotation of the stars through local sidereal time. The poster is only true for that one birthday.

Up to four moons, one price

A birth date, a wedding, the day you met, a child's first day. Four moments live on the same poster without changing what you pay.

Print it as big as you want

You download a 21,600 px file tagged at 360 DPI — up to 60 × 40 in. Print it once for the birthday and again years later from the same file.

Birthday moon questions

Enter your birth date above. We compute the moon's true illumination for that date, so you see the exact phase that was in the sky — the same calculation the studio uses for the final poster.

Yes. In the studio you set date, time and coordinates, and the sky rotates accordingly using local sidereal time — stars and constellation figures included.

It works for a first birthday, an 18th, a 30th or a 50th. You can also add up to four moons — a birth date plus other milestones — for the same price.

A digital art file, 21,600 px on the long edge and tagged at 360 DPI. Nothing is shipped: you download it and print it wherever you like, as many times as you like.

Up to 60 × 40 in (152 × 101 cm) at a full 360 DPI. A4, A3, 50 × 70 cm or 24 × 36 in come out razor sharp from the same master file.
