Frequently Asked Questions
How accurate is this age calculator?
Our age calculator is 100% accurate for chronological age calculations. It accounts for leap years, varying month lengths, and provides precise results down to the second based on your birth date.
What is chronological age?
Chronological age is your actual age measured from the exact moment of your birth to the current date. It's the standard way of measuring age used for legal, medical, and official purposes.
Can I calculate age between two dates?
Yes! By default, we calculate from your birth date to today. But you can also change the end date to calculate your age at any specific date in the past or future.
Why should I know my exact age?
Knowing your precise age can be useful for medical assessments, filling out official forms, planning milestone celebrations, or simply satisfying your curiosity about how long you've been alive!
How is this different from a face age test?
This calculator determines your real (chronological) age based on math. A face age test uses AI to analyze your facial features and estimate how old you appear to look - which can be different from your actual age!
