Understanding a person's age can vary across cultures due to different counting systems. This age calculator aligns with the prevalent age-counting system, where a person's age increases on their birthday. For example, if someone has lived for 3 years and 11 months, their age is considered 3, advancing to 4 on their upcoming birthday. This approach is commonly followed in Western countries.
On the contrary, certain cultures count years with or without including the ongoing year. In the traditional Chinese age system, individuals are considered to be born at age 1, and their age advances during the Traditional Chinese New Year instead of their birthday. For instance, a baby born a day before the Traditional Chinese New Year is considered 2 years old just two days later.
While using this age calculator, note that complexities may arise, especially when the starting date falls at the end of a month. For example, the period from Feb. 20 to Mar. 20 is counted as one month. When calculating age from Feb. 28, 2022, to Mar. 31, 2022, different approaches may yield varying results. The confusion stems from the different days in months, and in this calculator, we employ a method where Feb. 28 to Mar. 28 is considered one month and 3 days. This is just one example of how cultural and calendar differences can affect age calculations.
