Acceptance
By using Cosmic Age Again, you agree to these terms. If you do not agree, please do not use the site.
The service
Cosmic Age Again is a free, browser-based educational tool that calculates your age on other planets, the Moon phase on your birth date, your Pi and Phi ages, and your weight on other worlds. It is provided for entertainment and educational purposes.
No warranty
The tool is provided "as is" without warranty of any kind. Astronomical data is drawn from reputable sources (NASA fact sheets, Jean Meeus, Astronomical Algorithms) but small inaccuracies may exist. Do not rely on this tool for scientific or navigational work.
Accuracy of results
Planetary ages are computed from published orbital periods and are accurate to within the rounding shown. Moon phase illumination is accurate to roughly 1–2%. Weight calculations use standard surface gravity values.
