Find your exact age in years, months, and days — and how long until your next birthday.
Total Days Lived
Days to Next Birthday
Want a live countdown to your next birthday instead of a static number?
Create a Birthday Countdown →How this works
Enter your date of birth and this tool calculates your exact age as of today — down to the day — plus the total number of days you've been alive and how many days remain until your next birthday. Everything runs in your browser; we don't store or see your date of birth.
