A **Chronological Age Calculator** is a tool that helps you determine a person’s exact age based on their **date of birth (DOB)** and the **current date** (or another specific date you choose).

👉 **Chronological age** simply means the actual time a person has lived since birth, measured in years, months, and days. For example, if someone was born on **February 2, 1985**, and today’s date is **September 15, 2025**, the calculator would compute their precise age as **40 years, 7 months, and 13 days**.

### How it Works:

1. **Input Required**:

   * Date of Birth (DOB)

   * Current Date (or target date)

2. **Calculation Process**:

   * The calculator subtracts the DOB from the current date.

   * It then breaks the result down into years, months, and days.

3. **Output**:

   * Exact chronological age (Years, Months, Days).

### Uses of a Chronological Age Calculator:

* **Everyday Use**: Quickly know your exact age without manually calculating.

* **Medical & Health**: Doctors and researchers often use it to determine age-specific treatments, growth patterns, or eligibility for medical procedures.

* **Education**: Schools use it to check age eligibility for admission, especially in early childhood programs.

* **Sports & Competitions**: Used to verify the age of participants for age-based categories.

✅ In short, a **Chronological Age Calculator** is a simple but very useful digital tool that saves time, avoids mistakes, and gives a precise answer to “How old am I?”
