The Age Calculator is a tool that helps you figure out someone's age or the time difference between two dates. It shows the result in years, months, weeks, days, hours, minutes, and seconds. However, how age is calculated can vary depending on cultural traditions. This calculator uses the most common system, where a person's age increases on their birthday. For example, if someone is 3 years and 11 months old, their age is considered 3, and it will jump to 4 on their next birthday.

In some cultures, age is counted differently. For instance, in certain systems, people are born at age 1, and their age increases on a specific calendar event, like the Traditional Chinese New Year, rather than their birthday. So, a baby born just one day before the New Year could be considered 2 years old just two days later, even though they’ve only been alive for two days.

There can also be some confusion when calculating age between dates that fall at the end of months. For example, if you calculate the time from February 28 to March 31, there are two ways to interpret it:

1. Counting February 28 to March 28 as one month, making the result one month and 3 days.
2. Treating both February 28 and March 31 as the end of their respective months, making the result exactly one month.

Both methods make sense, but the calculator uses the first approach. Similar situations can arise with dates like April 30 to May 31 or May 30 to June 30, due to the varying number of days in each month. The calculator aims to provide clear and consistent results, but keep in mind that age calculations can sometimes be a bit tricky depending on the dates involved.
