What Are These Terms?
Chronological Age
Your chronological age is the actual time that has passed since your birth. It's different from biological age (health-based) or mental age (maturity-based). This calculator focuses on chronological age.
Age Breakdown
Instead of just saying "25 years old," a breakdown shows "25 years, 3 months, 14 days." This is useful for baby ages, insurance, legal documents, or precise record-keeping.
Total Days
The complete number of days you've been alive. For example, a 30-year-old has lived approximately 10,950 days. This perspective can be interesting and motivational.
