Leap Year Determination in Programming

A leap year is a year that is evenly divisible by 4, except for years that are divisible by 100 but not divisible by 400. This rule ensures that leap years are accurately calculated and occur approximately every four years.

Here's a stepbystep algorithm to determine whether a given year is a leap year:

def is_leap_year(year):
    if year % 4 == 0:
        if year % 100 == 0:
            if year % 400 == 0:
                return True
            else:
                return False
        else:
            return True
    else:
        return False
year = 2024
if is_leap_year(year):
    print(f"{year} is a leap year.")
else:
    print(f"{year} is not a leap year.")

When implementing leap year determination in programming, ensure to follow the algorithm carefully, considering the conditions for divisibility by 4, 100, and 400. Additionally, while the provided sample code is in Python, the same logic can be applied to other programming languages.

Remember to test your code with various input values to ensure its correctness. Leap year calculations are essential in various applications, such as calendar systems, date calculations, and scheduling tasks, so having a reliable leap year determination function is crucial.
