How do you determine if a year is a leap year?

Determining if a year is a leap year involves applying a simple set of rules. Here’s how you can check:

  1. Check if the year is divisible by 4: If a year is evenly divisible by 4, it may be a leap year. For example, 2020 and 2024 are divisible by 4.
  2. Check if it is not divisible by 100: If the year is divisible by 4 but also divisible by 100, it is not a leap year. For instance, the year 1900 is divisible by 100 but not by 400, hence it is not a leap year.
  3. Check if it is divisible by 400: If a year is divisible by both 100 and 400, then it is a leap year. For example, 2000 is a leap year because it is divisible by 400.

In summary, if a year is divisible by 4 and not divisible by 100, it is a leap year, unless it is also divisible by 400, in which case it remains a leap year.

Here’s a quick reference:

  • Leap years: 2020, 2024, 2000, 1600
  • Non-leap years: 1900, 2100, 2023

Understanding leap years is useful, especially for various calculations in date and time management.
