Normal Year vs Leap Year:
A normal year has 365 days.
A leap year has 366 days, with one extra day added to February.
So, in a leap year, February has 29 days instead of 28.
Why Do We Have Leap Years?
The Earth takes about 365.242 days to complete one full orbit around the Sun.
To keep our calendar year synchronized with the solar year, an extra day is added every 4 years.
This extra day compensates for the 0.242 extra days each year (≈ 6 hours).
Leap Year Rule (Gregorian Calendar):
A year is a leap year if:
It is divisible by 4,
But not divisible by 100,
Unless it is also divisible by 400.
Examples:
2020 → Leap Year (divisible by 4)
1900 → Not a Leap Year (divisible by 100 but not by 400)
2000 → Leap Year (divisible by 400)
2024 → Leap Year
