Age Calculator

This calculator finds the exact time elapsed between your date of birth and today, broken down into years, months, days, weeks, and total days.

It compares the calendar date components of today and your birth date, borrowing from the next larger unit when the day or month hasn't been reached yet — the same way you'd count age by hand, just automated and exact down to the day.

Example: Someone born on June 15, 1990 turns 36 on June 15, 2026, and on June 29, 2026 they'd be 36 years, 0 months, and 14 days old — roughly 13,163 total days.
