FAQ
How is age calculated?
The full years elapsed from birth to the reference date is your age; remaining months and days are shown as detail.
Can I change the reference date?
Yes. It defaults to today, but you can set any reference date to compute age as of that day.
Is my birth date sent to a server?
No. All calculations happen in your browser and nothing leaves your device.
