📊 How Age Calculation Works

1. Basic Age Formula

$\text{Age} = \text{Current Date} - \text{Date of Birth}$Age=Current Date−Date of Birth

---

2. Total Days Lived

$\text{Total Days} = \frac{\text{Milliseconds Difference}}{86{,}400 \times 1000}$Total Days=86,400×1000Milliseconds Difference​

---

3. Hours and Minutes Conversion

$\text{Hours Lived} = \text{Total Days} \times 24$Hours Lived=Total Days×24

$\text{Minutes Lived} = \text{Hours Lived} \times 60$Minutes Lived=Hours Lived×60

---

4. Next Birthday Countdown

$\text{Days Until Birthday} = \text{Next Birthday Date} - \text{Today}$Days Until Birthday=Next Birthday Date−Today

---

🎯 Example Scenario

Date of Birth:

10 June 2000

Today:

Current Date

Output:

• Age: 25 years (approx.)
• Total days lived: 9,000+ days
• Hours lived: 200,000+ hours
• Next birthday: countdown active
