Client-side only. No data leaves your device.
Frequently Asked Questions
How precise is the age calculation? It calculates the exact number of years, months, and days from your date of birth to today (or a custom date). Leap years and varying month lengths are handled correctly.
Can I calculate age at a past or future date? Yes — use the ‘Calculate age on’ option to set any target date, not just today.
What else does it show? Your age in total days lived, and the number of days until your next birthday.
