What is an Age Calculator?

An age calculator is a tool that determines the precise duration between two dates, typically from your birth date to the current date. It provides a detailed breakdown of your age in various units including years, months, days, hours, minutes, and seconds.

How to Use the Age Calculator

Using our age calculator is simple:

  1. Enter your birth date in the first field
  2. Optionally, enter a different end date (default is today)
  3. Click the "Calculate Age" button
  4. View your age in different formats

You can recalculate as many times as you'd like with different dates.

Why Calculate Your Age?

There are many reasons to calculate your exact age:

  • Determining eligibility for age-specific benefits or programs
  • Tracking developmental milestones for children
  • Planning age-related celebrations or events
  • Satisfying curiosity about how many days, hours, or seconds you've been alive
  • Calculating time between any two important dates

How Age is Calculated

Our age calculator uses precise algorithms to determine the exact duration between two dates. Here's how the different units are calculated:

Years, Months, and Days

The calculator first determines complete years between the two dates, then calculates remaining months, and finally the remaining days. This approach accounts for varying month lengths and leap years.

Weeks and Days

The total number of days is divided by 7 to determine complete weeks, with the remainder representing additional days.

Hours, Minutes, and Seconds

These units are calculated based on the total number of milliseconds between the two dates, converted to their respective units.

  • Hours = Total days × 24
  • Minutes = Total hours × 60
  • Seconds = Total minutes × 60
