Exact Age Calculator

The standard Age Calculator is the foundation of our platform. While most people think of age in years, time is far more precise. This tool gives a clear, detailed breakdown of the time that’s passed from your birth (or any chosen start date) to the present moment—down to smaller units. That extra accuracy is especially useful for insurance forms, medical records, and legal eligibility where exact timing matters.

One of the unique features is the "Age at a Specific Date" function. This allows you to travel back in time to see exactly how old you were during Historical Events or project into the future to see your age on a Retirement Milestone. If you are comparing two people, our Age Difference Calculator is a better fit.

The algorithm handles the "February problem" with ease. Calculating age when the start or end date falls on February 29th is a common point of failure for simpler calculators. We ensure your results are always legally and mathematically sound, even if you were born on a leap day.
