Find your exact age in years, months, and days — instantly, right in your browser.
This free age calculator finds your exact age in years, months, and days from your date of birth — no guessing, no manual counting of months. It also shows your total days lived, total weeks and months lived, which day of the week you were born on, and a countdown to your next birthday. It's useful for filling out official forms, checking eligibility requirements based on age, or just satisfying curiosity.
You can also calculate someone's age "as of" a specific date in the past or future — handy for exam eligibility cut-offs, legal age requirements, or planning ahead. Everything runs instantly in your browser; your date of birth is never uploaded or stored anywhere.
We take your date of birth and the current date (or a date you choose), then calculate the exact difference in years, months, and days — accounting correctly for varying month lengths and leap years.
No. The calculation happens entirely in your browser using JavaScript. Nothing is uploaded or saved to any server.
Yes — use the optional 'Calculate Age As Of' field to find out how old someone was, or will be, on any specific date, such as an exam date or a legal deadline.
The result shows exactly that, calculated directly from your date of birth.
