Frequently asked questions
Why do the year pages show two possible ages?
Because age depends on whether this year's birthday has passed. Someone born in 1998 is 27 until their 2026 birthday, then 28. Enter the full birth date for a single exact answer.
Is my data stored when I enter a birthday?
No. Every calculation runs in your browser with JavaScript; nothing is sent to a server.
How is exact age calculated?
Calendar arithmetic: completed years, then completed months, then leftover days, the convention used by schools, clinics, and government forms.
