🎂 Age Calculator
Find your exact age in years, months and days — completely free.
What is the Age Calculator?
Age Calculator is a free tool that tells you exactly how old you are — not just in years, but in months, days, weeks, even hours. It also counts down the days until your next birthday, which is handy when you're filling a form that asks for your age "as of" a specific date.
💡 Key Feature: Get your age in years, months and days, plus total days lived and a next-birthday countdown — completely free, nothing is stored.
How to Use the Age Calculator
- Enter your date of birth in the first box.
- (Optional) Pick an "as of" date if you need your age on a past or future date — for a school admission or visa form, for example.
- Click "Calculate Age" and read your result.
