Questions
Can I count an age on another date?
Yes — change the "On" date. That is how you check an age on the day of an exam, a trip or a contract.
What about someone born on 29 February?
In a common year the birthday is counted on 28 February, so the next-birthday line never skips a year.
Is the date of birth stored anywhere?
No. It is counted in the page and not even remembered by the browser: the field is empty next time.
