Accurate Age Calculator

The Age Calculator is a tool designed to accurately calculate the age or time interval between two given dates. It provides the calculated result in various units, including years, months, weeks, days, hours, minutes, and seconds.



The Age Calculator provided here follows the common age system widely used in most Western countries. According to this system, a person's age increases on their birthday. For instance, if someone has lived for 3 years and 11 months, their age is considered to be 3. When their next birthday arrives, one month later, their age will increment to 4. It's important to note that different cultures may have alternative ways of counting age. In certain cultures, age may be expressed by including or excluding the current year when counting. For example, someone who is twenty years old can be considered to be in their twenty-first year of life. Traditional Chinese age systems, for instance, assign age 1 at birth, and age increases during the Traditional Chinese New Year instead of the individual's birthday. For example, a baby born one day before the Traditional Chinese New Year would be considered 2 years old just two days later, despite being only 2 days old. The calculation of months and days in this age calculator may sometimes lead to confusion, particularly when the starting date falls at the end of a month. For instance, while we count the period from February 20 to March 20 as one month, calculating the age from February 28, 2022, to March 31, 2022, can yield different results. If we consider February 28 to March 28 as one month, the result would be one month and 3 days. However, if we treat both February 28 and March 31 as the end of the month, the result would be one month. Both interpretations are reasonable, and the choice depends on the specific context. Similar situations arise with dates like April 30 to May 31, May 30 to June 30, and so on. In our calculations, we adopt the former method mentioned above.
