What it does
A free age calculator that returns your exact age in years, months, and days — plus total months, weeks, days, and hours lived, and days until your next birthday. Enter your birthdate and a target date; everything computes live in the browser.
Age calculators are useful for forms that need exact age-at-date, planning milestones (retirement, eligibility), or just curiosity. The total-days-lived number is a surprisingly motivating number to know — it’s finite, it’s counting, and it puts daily habits in perspective.
How to use it
- Enter your birthdate.
- Optionally set a target date (defaults to today).
- Read your age in years/months/days, plus total units lived.
- Check the countdown to your next birthday.
