What Moon were you born under?

Enter your birthday to see the Moon's phase, how much of it was lit and the sign it was in on the day you were born.

An example. Yours appears below.
Your birthday
Type a four-digit year from 1930 to 2026.

We compute your reading, then let go of your birthday. Unless you make a free account, it's never saved on our servers.

How it works

We compute the Moon's position for your birth date with Astronomy Engine, the same open-source library behind every Signology reading.

Without a birth time we read the phase at noon and list both signs if the Moon changed signs that day. The Moon moves about 13 degrees a day, so the hour matters for the sign.
