Frequently asked questions
How is the age expressed?
We give it in years, months and days, plus totals in days, weeks and months, plus the days until your next birthday.
Does it handle leap years?
Yes. We use the calendar's actual month lengths and February 29 birthdays are advanced to March 1 in non-leap years.
Can I compute age at a specific past or future date?
Yes — change the 'At date' field. Useful for checking how old someone was on a particular event, or how old they'll be on a future date.
