⚙️ HOW IT WORKS
Simply enter your birth date and target end date. Our algorithm accounts for:
- Leap years and varying month lengths
- Scientific averages for biological estimates
- Astronomical cycles for lunar calculations
- Global demographic data
All calculations are performed client-side—no data is stored or transmitted.
✨ WHY IS THIS BETTER THAN OTHERS?
Most age calculators are simple date subtractors. RexaAge is a biological and astronomical engine. Here is the difference:
We don't just say you are "30 years old." We tell you how many heartbeats you've spent, how many full moons you've seen, and where you stand in global population demographics. It gives you a perspective on life, not just a number.
Entering your birth date is sensitive data. Other sites might track this to build a profile on you. RexaAge runs 100% in your browser. We physically cannot see your date of birth.
❓ FREQUENTLY ASKED QUESTIONS
Absolutely. Your input is processed instantly by JavaScript on your own device. We do not have servers that collect this data.
We calculate the next significant round number in seconds, minutes, hours, or days (e.g., your 1 billionth second) to give you something to look forward to.
These are scientific estimates based on global averages (e.g., average heart rate of 80 bpm, average breaths per minute). They are for fun and perspective, not medical diagnosis.
Yes, our algorithm strictly adheres to the Gregorian calendar, accounting for every leap year since your birth.
