Age Calculator

What is an Age Calculator?

An age calculator is a specialized tool that determines your exact age by calculating the time difference between your date of birth and a target date (usually today). Unlike simple year calculations that can be inaccurate, our age calculator accounts for leap years, varying month lengths, and provides your precise age in multiple formats - years, months, days, weeks, hours, and even minutes. It also shows when your next birthday is and how many days until you celebrate it, making it perfect for personal use, legal documentation, or just satisfying your curiosity about how long you've been alive.
