Age Caculator

Age Calculator

The Age Calculator determines your age or the interval between two dates. It displays the result in years, months, weeks, days, hours, minutes, and seconds. Simply enter your date of birth and the target date, then click "Calculate Age" to see the results.

Note: Age calculation varies across cultures. This calculator uses the most common system, where age increases on a person's birthday. For example, someone who has lived for 3 years and 11 months is considered 3 years old, and their age will increase to 4 on their next birthday.

In some cultures, age is counted differently. For instance, in traditional Chinese systems, a person is born at age 1, and their age increases during the New Year rather than their birthday.
