There are few definitions for days, some definitions will say it starts at zero, some others will tell it is interval of 24 hours, not necessarily starting at zero, and some definition will speak of daylight period. So if business starts on Monday 08:00 o'clock -- or maybe in Sweden at 09:30 o'clock (they have have time...) and it maybe closes at 16 o'clock or in Sweden maybe 18:00 o'clock, then we have interval from Monday 08:00 o'clock to Friday 18:00 o'clock Swedish opening hours, that yields result of: SELECT '2021-03-26 18:00'::timestamp - '2021-03-22 08:00'::timestamp; ?column? ----------------- 4 days 10:00:00 (time-from-to "2021-03-22 08:00" "2021-03-26 18:00") => 4 days 10:00:00 (defun time-from-to (from-date to-date) "Returns days passed from FROM-DATE to TO-DATE in format YYYY-MM-DD." (string-trim (shell-command-to-string (format "psql -Aqtc \"SELECT '%s'::timestamp - '%s'::timestamp;\"" to-date from-date)))) But then again it may be deceptive, we did not calculate working hours, rather full difference, as worker did not work really 4 days and 10 hours, but rather maybe 8 hours x 5 = 40 hours, which equals to some 1.6 full days in a week. There are 365 days in a year, 52 weeks, one month or 4 weeks is usually some kind of holiday, there are maybe few more holidays. 48 weeks x 1.6 full days yields with actual work of 77 days in a year of 365 years, just 21% of the year time, and then so many will keep complaining for overwork and whatever other reasons. We are lazy.
