🌍 What Is a Leap Year?
A leap year is a year with an extra day—February 29th—added to keep our calendar in alignment with the Earth's revolutions around the sun. A year is a leap year if:
- It is divisible by 4,
- But not divisible by 100,
- Unless it is also divisible by 400.
For example:
- 2000 ✅ Leap year (divisible by 400)
- 1900 ❌ Not a leap year (divisible by 100 but not 400)
- 2020 ✅ Leap year (divisible by 4 but not 100)

🔍 Behind the Scenes: How It Works
The core logic of the calculator uses a simple loop to count leap years:
if ((year % 4 === 0 && year % 100 !== 0) || (year % 400 === 0)) {
leapCount++;
}
This follows the official leap year rule. It checks each year from your birth year to the current year and adds to the count if the conditions are met.
