📘 About the Age on Moon
A "Moon year" is not a real calendar year, but you can count your age in lunar orbits: the Moon goes once around the Earth every 27.32 days. Enter your date of birth and this calculator divides your exact age in days by that period to tell you how many times the Moon has circled the Earth since you were born.
Every year you live, the Moon circles the Earth about 13.4 times. The result also shows the date of your next full lunar orbit, your exact age on Earth, and a table of your age on every planet.
🧮 Formula
This uses the sidereal month (27.32 days). New moon to new moon takes 29.53 days.

💡 Facts about the Moon
- The Moon always shows the same face to Earth because it spins once for every orbit.
- From new moon to new moon (the lunar or synodic month) takes 29.53 days, a little longer than one orbit.
💡 Your age on each planet
For a 30-year-old: Mercury 124.5 years, Venus 48.8, Earth 30, Mars 15.9, Jupiter 2.5, Saturn 1.0, Uranus 0.36, Neptune 0.18 and Pluto 0.12 years. The table in the result shows your own figures.
❓ Frequently asked questions
How old am I in Moon years?
Multiply your age in years by about 13.37 (or divide your age in days by 27.32). A 30-year-old has lived about 401 lunar orbits.
How long does the Moon take to orbit the Earth?
27.32 days relative to the stars (sidereal month); 29.53 days from new moon to new moon.
How old is the Moon?
About 4.5 billion years. It probably formed from debris after a Mars-sized body hit the young Earth.
When does my next lunar orbit complete?
The result shows the exact date, counted from your date of birth.
Is this exact?
Yes: it uses your exact age in days and the planet's orbital period. Earth years are taken as 365.256 days in the comparison table.
