Chronological age refers to the number of years an individual has lived since birth, serving as a fundamental measure of their age in terms of time passed.

Chronological age is commonly used in various contexts, including social, legal, and medical fields. It helps determine milestones, rights, and eligibility criteria based on age-related requirements.

Chronological age is calculated by subtracting an individual’s birthdate from the current date, accounting for the number of years, months, and days that have passed.

While chronological age provides a basic understanding of a person’s age, it may not account for individual variations in physical, mental, or emotional development, which can differ among individuals of the same age.

It is important to consider contextual factors, such as cultural, socio-economic, and environmental influences, as these factors can impact an individual’s experiences and development at a given chronological age.
