Use the above Online age Calculator to calculate the age on a specific day.

This calculator is based on the most common age system. In this system, age grows at the birthday. Most western countries use this age system.

In some cultures age is expressed by counting years with or without including the current year. For example, one person is twenty years old is the same as one person is in the twenty-first year of his/her life. In one of the traditional Chinese age systems, people are born at age 1 and the age grows up at the Traditional Chinese New Year instead of birthday. For example, if one baby was born just one day before the Traditional Chinese New Year, 2 days later the baby will be at age 2 even though he/she is only 2 days old.
