About This Tool

The Age Calculator allows you to calculate the exact age or time interval between two dates. It provides results in years, months, weeks, days, hours, minutes, and seconds, making it a versatile tool for personal or professional use.

The tool adheres to the most commonly used age calculation system, where age increases on the person's birthday. For example, someone who has lived for 3 years and 11 months is considered 3 years old, with their age increasing to 4 on their next birthday. This approach is widely adopted in Western countries.

Different cultures may calculate age differently. For example, in some traditions, a newborn is considered 1 year old at birth, and their age increases at the start of the new year instead of on their birthday. These variations reflect cultural differences in how age is perceived.

Note that certain edge cases, such as calculating age between months with different numbers of days, may lead to slight variations. For instance, calculating from February 28 to March 31 could result in one month and 3 days, depending on whether end-of-month dates are treated as equivalent. This calculator follows the more intuitive method for such scenarios.
