🎂 Age Calculator
Get exact age in years, months, and days from a birthdate.
About this tool
Calculates exact age in years, months, and days from a birthdate to today — plus the total number of days lived, if you're curious.
For the gap between any two dates that aren't today — like counting down to an event — the Date Difference Calculator is the more flexible option.
Worked example
Someone born January 15, 1994 turns out to be 32 years, 7 months, and roughly 16 days old as of today — about 11,918 days lived.
How to use it
- Pick your date of birth using the date field.
- Press Calculate age.
- See your exact age broken down by years, months, days, and total days.
Tips
- This calculates age as of today's date automatically — no need to enter today's date.
- Total days lived is a fun stat for milestone tracking (10,000 days old, etc).
- For age on a specific future or past date rather than today, use the Date Difference Calculator instead.
FAQ
Does this account for leap years?
Yes, it uses actual calendar dates so leap years are handled correctly.
Can I calculate age as of a different date, not today?
Not directly with this tool — use the Date Difference Calculator for that.
Why do months and days look odd near month boundaries?
Because months have different lengths — the calculator adjusts for the actual number of days in each month.
