Try our versatile Age Calculator to accurately determine your age based on birthdays and various cultural differences. Get started now!

Age calculation varies across cultures. This calculator follows the widely used system where age increases on birthdays. For example, a person who is 3 years and 11 months old turns 4 on their next birthday.

Some cultures count age differently. In a traditional Chinese system, a newborn is considered 1 year old at birth, with age increasing on the Chinese New Year instead of their birthday. This means a baby born just before the New Year could be considered 2 years old within days.

Age calculations can also be tricky near month-end dates. For instance, from February 28 to March 31, the result can vary based on how months are counted. This calculator follows the method where February 28 to March 28 is one month, with extra days counted separately.
