Here’s how to use it to calculate your age or the duration between any two dates.

🗓️ Step 1: Enter the Start Date (Your Birthday)

The calculator defaults to today's date for both fields. To calculate your age, click on the "Start Date" field and use the calendar to select your date of birth.

This calculator uses the most common age system, where your age increases on your birthday each year.

📅 Step 2: Enter the End Date

The "End Date" field is used to determine the age at a specific point in time. By default, it's set to today, which calculates your current age. You can change this to any future or past date to calculate an age at that specific time.

⏳ Step 3: See the Results

The moment you select the dates, the calculator instantly displays the result. You’ll see a primary breakdown of the duration in years, months, and days.

Below that, you'll find an even more detailed breakdown, showing the total duration in weeks, days, hours, and even minutes. It's a fun way to see just how long you've been around!

💡 Other Uses for the Age Calculator

This tool isn't just for birthdays. You can use it to calculate the time between any two dates:

  • Find out the exact duration of a historical event.
  • Calculate how long it's been since a significant milestone.
  • Determine the exact time remaining until a future event or deadline.

It's a versatile tool that works as a powerful Duration Calculator, giving you precision down to the second.
