How to use: Enter your date of birth and Snumly instantly shows your exact age in years, months and days — plus total days lived, weeks, and a countdown to your next birthday.
The Snumly age calculator tells you exactly how old you are — not just in years, but broken down into years, months, days, total days lived, total weeks, and even a countdown to your next birthday.
Whether you need your precise age for a form, want to know how many days you've been alive, or are simply curious — this tool gives you an instant, accurate answer. Just enter your date of birth and results update in real time.
Unlike a simple age calculator that only shows years, Snumly breaks your age down into every meaningful unit so you get the complete picture.
How do I calculate my exact age?
Enter your date of birth in the field above and the calculator instantly shows your exact age in years, months and days, updated to today's date.
How many days old am I?
The calculator shows your total days lived beneath the main result. Most adults are surprised to find they've lived well over 10,000 days.
How do I find out how many days until my next birthday?
The 'Days to birthday' figure shows exactly how many days remain until your next birthday, updated daily.
Can I use this to calculate someone else's age?

Why does my age show differently on different calculators?
