How it works
The calculator compares the year, month, and day between the birth date and the reference date. If the current month or day is earlier than the birth date, the calculation borrows from the previous month or year.
- Leap years: Automatically handled.
- Exact breakdown: Returns years, months, and days.
- Optional reference date: Calculate age at any past or future date.
Examples
- How old am I if I was born on 2000-01-01? → Depends on today's date.
- Age from 1995-10-10 to 2026-02-24 → 30 years, 4 months, 14 days
- Born on Feb 29? → Leap years are handled correctly.
