// Code-Comprehension Exercise: proof that the function `weekDayOfDate` only return integers in
// interval [0;6].


// Unit-Test Exercises: Make Unit Test for other functions

// Exercise 1: assert that `countDaysOfMonth` works for leap years (for example 2032)

// Exercise 2: assert that `weekDayOfDate` works for leap years
