What does the Age Calculator do?
The Age Calculator works out your exact age in years, months, and days from your date of birth. Enter your birth date (and optionally a reference date), and the tool calculates precisely how much time has passed, breaking it down into all its units.
Common uses
- Find your exact age — get your precise age in years, months, and days for forms, records, or curiosity
- Plan milestones — see when your next birthday falls and how many days are left
- Verify eligibility — check age for appointments, registrations, or legal requirements
- Track children's growth — record exact ages in months and days for babies and young children
Key features
- Exact age — reports age down to the day, not just whole years
- Next birthday — shows the date of your upcoming birthday and how long until it arrives
- All units — presents the same age in years, months, weeks, days, hours, and minutes
How it works
An age is computed by counting full years, then remaining months, then remaining days between the birth date and the current (or chosen reference) date. The calculator accounts for calendar differences — such as months of unequal length and leap years — so the result matches the real calendar rather than a simple 365-day average. It also highlights when the next birthday falls and how many days separate you from it.
Verdict
The Age Calculator gives you a precise, calendar-correct age in every unit you could need. Open Age Calculator and get your exact age in seconds.
