Astral Age Calculator

How old are you on Mars? How many full moons have you lived through?

Astral Age measures your life in the clocks of the solar system. Enter your birth date and time and see your age in Earth days, Moon cycles, and years and days on every planet from Mercury to Pluto. Then it counts down to your next big number.

EARTH
Your age in years, months, weeks and days, with a live counter and a globe that turns with you.

THE MOON
Every full moon cycle since you were born, and how long until the next one.

THE PLANETS
Your age on Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. A year on Neptune lasts almost 165 Earth years, so few of us will see our first. A day on Jupiter is under 10 hours long, so you've lived through far more of those than days on Earth.

MILESTONES
Astral Age finds the round numbers ahead of you, like your 10,000th day or your 500th month. Get a notification at the exact moment one arrives, or add it to Apple Reminders. Celebrate your first milestone to unlock a hidden game.

SHARE IT
Send your Mars age or your next countdown to friends as a ready-made card.
