What is Chronological Age?
Chronological age simply means the amount of time you’ve lived since your birth. It is calculated starting from your date of birth (DOB) to the current date.
📌 Example:
If someone was born on 10th March 2000 and today’s date is 31st August 2025, their chronological age is 25 years, 5 months, and 21 days.
This is the most common way age is measured in everyday life, whether it’s filling out forms, checking eligibility, or tracking milestones.
👉 Note: Chronological age is different from biological age (how old your body seems based on health and lifestyle) and mental age (cognitive abilities compared to age norms).
