Birth moon lookup
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.
Waning Gibbous · 97% illuminatedJune 14, 1995
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.
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.
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.
Enter the birth date, the time and the city. Add more moments if the gift calls for it.
Choose a moon collection, a frame, a typeface and the names or message under the moon.
Pay once and get the 360 DPI art file instantly. It stays re-downloadable in your account.
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.
