About this app

Kepler Age is a simple and accurate tool that calculates your true orbital age using real astronomical year definitions. Instead of relying only on the standard civil year, the app compares your age across multiple time systems, including the tropical year, sidereal year, and more. This provides a detailed view of how much time you have lived based on Earth’s actual orbital motion.

All calculations are performed entirely on your device. No data is collected, stored, or transmitted.

Key features:

• Calculate your age across different astronomical year types
• View your lived time in years, months, days, hours, minutes, and seconds
• Compare civil, tropical, and sidereal year age results
• Discover time lived since key events with the Saved Dates feature
• Learn the history behind orbital year definitions in the built-in reference section
• Light and dark themes for comfortable viewing
• No accounts, no ads, and no internet connection required

Everything in Kepler Age runs locally, ensuring speed, accuracy, and complete privacy. Whether you are interested in astronomy, enjoy time-based insights, or simply want a new perspective on the passage of your life, Kepler Age provides a clear and easy way to explore your lived time.

Kepler Age is educational, privacy-friendly, and designed for users of all ages.
