Different Ways to Calculate Age
Age calculation can vary across different cultures and contexts. This calculator uses the most common age system where age increases on a person's birthday.
For example, someone who has lived for 3 years and 11 months is considered 3 years old until their next birthday, when they turn 4. This system is used in most Western countries.
In some cultures, like the traditional Chinese age system, people are considered to be 1 year old at birth, and their age increases at the Chinese New Year rather than on their birthday.
Our calculator provides precise measurements in multiple time units to give you a complete picture of the time elapsed between any two dates.
