问题 I was trying to search for the answer, but I couldn't find any. I'm trying to create a JavaScript function, that takes two dates and returns a string in the format of "x years, y months, z days, a hours, b minutes, c seconds".

问题 I'm trying to calculate business hours between two dates. Business hours vary depending on the day. Weekdays have 15 business hours ( 8:00-23:00 ), saturdays and sundays have 12 business hours ( 9:00-21:00 ). For example: start date 07/24/2020 22:20 (friday) and end date 07/25/2020 21:20 (saturday), since I'm only interested in the business hours the result should be 12.67 hours.
