checks whether given year is a leap year or not How to determine whether a year is a leap year To determine whether a year is a leap year, follow these steps:

  1. If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.

  2. If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4.

  3. If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5.

  5. The year is not a leap year (it has 365 days).

bool checkLeapYear(int year) =>
    year % 400 == 0 || (year % 4 == 0 && year % 100 != 0);
