Find out your age in years, months, days, and more - instantly.
Our free Age Calculator instantly tells you exactly how old you are, down to the year, month, and day, simply by entering your date of birth. While most people know their age in years, this tool goes further by breaking your age down into total months, total weeks, total days, and even total hours you have been alive, giving you a precise and often surprising picture of your age. It also calculates exactly how many days remain until your next birthday, which is a fun detail many people enjoy checking.
Calculating exact age manually is more complicated than it seems, since it requires accounting for varying month lengths and leap years. A simple subtraction of birth year from the current year often gives an inaccurate result, especially if your birthday has not yet occurred this year. Our calculator handles all of this automatically using precise date arithmetic, so the result you see is always accurate regardless of when in the year you check it.
This tool is useful for a wide range of purposes: filling out official forms that require an exact age, checking eligibility requirements for age-restricted services, satisfying simple curiosity about milestones like your 10,000th day of life, or planning birthday celebrations. It works for any date of birth and updates its calculation instantly and accurately every time you use it.
This tool is completely free to use, requires no signup, and does not store your date of birth anywhere. Simply enter the date, click calculate, and get your precise age breakdown in seconds.
