What is Age Calculation?

Age calculation is the process of determining the exact amount of time that has elapsed since a person was born. While most people simply track their age in years, our calculator breaks it down into months, weeks, days, and even live-updating hours and minutes.

How is age calculated?

Our tool uses the standard western method for calculating age, where a person's age increases by one year on their birthday. The exact days and months are calculated by taking the exact number of days in each specific month between the dates, correctly accounting for leap years.
