❓ Frequently Asked Questions
How does the age calculator work?
The calculator computes the exact time difference between your selected birth date and the current or target date, factoring in leap years and varying month lengths for accurate results.
Is my birth date data saved?
No, all calculations are performed locally in your browser. We never store or transmit your personal data.
Can I calculate age for a future date?
Yes, you can select any past or future target date to calculate what your exact age was or will be on that specific day.
Does the Age Calculator work offline?
Yes, the Age Calculator is fully functional offline. Because this tool runs entirely in your browser, no data is ever uploaded to external servers. Once the page is loaded, you can seamlessly continue using it without an active internet connection. You can also install Knicknaks as a Progressive Web App (PWA) for native-like offline access.
