About Age Calculation
Age calculation is the process of determining the elapsed time between a person's birth date and the current date (or another specified date). While it seems simple, accurate age calculation involves several complexities:
Different Ways to Calculate Age
- Calendar Age: The most common method, counting years, months, and days since birth.
- Lunar Age: Used in some cultures, based on lunar calendar cycles.
- Developmental Age: Used in pediatrics to assess a child's development relative to peers.
