If you want to know your age on another planet, this is the calculator that will help you find out your age on other planets. Simply enter your Earth birth date, choose a planet and find out how old you will be in planetary years, days and time units. Learn how time changes in the solar system and find out your age on Mars, Jupiter and beyond.
Your age on Earth is calculated based on how many times the Earth has orbited the Sun, for example, one Earth year = 365.25 days. But other planets take more or less time to orbit the Sun. It depends on their distance and speed - this is called their orbital period.
So, if you were born on Mars, your Martian age would be different from your Earth age, because a Martian year is longer.
| Planet | Orbital Period (Earth Days) | 1 Planet Year = Earth Years |
|---|---|---|
| Mercury | 88 | 0.24 years |
| Venus | 225 | 0.62 years |
| Earth | 365.25 | 1.00 year |
| Mars | 687 | 1.88 years |
| Jupiter | 4,333 | 11.86 years |
| Saturn | 10,759 | 29.46 years |
| Uranus | 30,687 | 84.01 years |
| Neptune | 60,190 | 164.8 years |
| Pluto | 90,560 | 248.0 years |
Note: Planetary months and weeks are ideas to help us understand time on other planets. A planet's year is the time it takes for it to revolve around the sun, and is divided into 12 planetary months or about 52 planetary weeks. These are based on space data, for Earth, a year counts as 365.25 days.
