Age Calculator
Pick a famous person with a documented birth date, or enter any birth date yourself, and get the exact age in years, months and days — computed live, never looked up from a table. For people who have died, it shows their age at death.
Frequently asked questions
How is the age calculated?
From the birth date to the date you choose (today by default), counting whole years, then whole months, then remaining days. The calculation runs in your browser and is exact for the dates you enter.
How does the calculator handle a 29 February birthday?
In a leap year the birthday is 29 February. In a non-leap year there is no 29 February, so the birthday is counted on 28 February — the convention most commonly used for leap-day birthdays. The calculator says so on the result, so the rule is never hidden.
What does it show for someone who has died?
When you pick a person who has died, the calculator uses their date of death and shows their age at death. It also shows what their age would be today, clearly labelled, so the two figures are never confused.
Why do some famous people not appear in the list?
Only people whose biographies are published on Top Personalities and whose birth date is reliably documented appear in the list. Anyone else's age can still be worked out by entering their birth date manually.
Is my entered birth date stored or sent anywhere?
No. What you type stays in your browser and is not sent to us; loading the page itself contacts our host, as explained in the Privacy Policy.
