Working Hours Calculator

Write a function that takes two dates and two times as input and returns the total number of working hours between the two dates (incl. both). Times representing the start and end of a workday. Working hours are defined as the time between the end and start times, Monday through Friday, excluding holidays. So the function also takes an argument that specifies an array of holidays to exclude (could be empty).
Time may have minutes. Convert them into float as minutes/60 with two-digits precision.
Input: Five arguments: two dates as strings (string), two times as strings, holidays as array of strings.
Output: Number of total working hours as integer or float (number).
Examples:
assert.strictEqual( workingHours("2023-03-01", "2023-03-01", "09:00", "17:00", []), 8 ); assert.strictEqual( workingHours("2023-03-01", "2023-03-02", "09:00", "17:00", []), 16 ); assert.strictEqual( workingHours("2023-03-01", "2023-03-03", "09:00", "17:00", ["2023-03-01"]), 16 ); assert.strictEqual( workingHours("2023-03-01", "2023-03-05", "08:45", "17:10", ["2023-03-03"]), 16.83 );
How it’s used: counting a total number of working hours, made by a worker or a machine is a usual thing at enterprises.
