🎂 About Us

AgeCalc started from a simple frustration: most "age calculator" websites either round their answers, hide the tool behind ads and pop-ups, or make you create an account just to find out how old you are. We wanted a set of calculators that just work - instantly, accurately, and without asking for anything in return.

What We Build

AgeCalc is a free collection of age and date tools: an exact age calculator, a date difference calculator, an age-on-a-specific-date tool, a birthday countdown, an age comparison tool, dog and cat age converters, and a baby age tracker. Every tool uses real calendar-date math - full years, then full months, then remaining days - so the numbers match what you'd get counting by hand on a calendar, not a rough estimate.

Our Principles

Accurate. Every calculation accounts for leap years and the real length of each month. Private. Calculations run entirely in your browser; nothing is sent to a server unless you choose to sign in and save a birthday for quick reuse, and even then that data stays in your browser's local storage. Free. No sign-up is required to use any calculator, there's no paywall, and there never will be for the core tools.
