Age Calculator
Free age calculator. Enter your date of birth to find your exact age in years, months and days, total days lived, and how long until your next birthday.
How exact age is calculated
Your age is computed calendar-accurately: full years first, then remaining full months, then leftover days — correctly handling different month lengths and leap years. That's why it can differ from simply dividing days by 365.
Use the optional "as of" date to find your age on a specific day — useful for exam eligibility cut-offs, government forms and job applications that ask for age as on a given date.
