What is Age Calculator?
Calculating someone's exact age — in years, months, and days — from a birth date is surprisingly complex due to varying month lengths and leap years. DailyDevTools' Age Calculator gives you the precise age from any birthdate to today (or any target date), and also shows the next birthday countdown, age in total days, and age in other units like weeks and hours.

Frequently asked questions
How is age calculated for people born on February 29?
For leap day birthdays, age increments on March 1 in non-leap years, which is the convention used in most countries. The calculator handles this edge case correctly.
Can I calculate the age of something other than a person?
Yes. The calculator works for any date — use it to find the age of a company, a building, a domain registration, or any historical event.
What is the most accurate way to express age?
The most precise expression is years + months + days (e.g., 28 years, 4 months, 12 days). For legal purposes, age is typically just the number of completed years.
