How many full moons have you lived?

Enter your birthday. We count every full moon from that day to tonight, one by one.

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

A full moon comes about every 29.5 days, so a year holds 12 or 13 of them.

We compute each full moon with Astronomy Engine, from the start of your birthday to now.
