What is Age Calculation?
Age calculation is the process of determining the amount of time that has passed since a person’s birth date. It is typically expressed in years, months, and days. Age is a fundamental demographic measurement used worldwide for various purposes including legal documentation, healthcare, education enrollment, retirement planning, and social interactions.
The calculation takes into account the complexities of the calendar system, including months with different numbers of days (28-31 days) and leap years that add an extra day to February every four years. This ensures accurate age determination regardless of when someone was born.
