About This Calculator
This calculator is based on the most common age system where age increases on a person's birthday. For example, the age of a person who has lived for 3 years and 11 months is 3, and their age will increase to 4 on their next birthday one month later.
In our calculations, we consider the uneven number of days in different months. For example, we count Feb. 20 to Mar. 20 as one month, even if the months have different lengths.
