Counting Days in Specific Month between Two Dates

bilionut — Wed, 25 Nov 2020 16:16:04 GMT

Hi to All,

Starting from this post:

Counting Days in Specific Month between Two Dates

I need to use the date format including hour and minute

For example between 01.01.2017 00:00:00 and 01.02.2017 12:00: 00 it should be 1.5 days

In the following example, room "w" should have been occupied 100%, meaning 31 days, but after running the script below the result is a total of 34,4999 days and 111%

Where is the mistake?

SET ThousandSep=',';

SET DecimalSep='.';

SET MoneyThousandSep=',';

SET MoneyDecimalSep='.';

SET MoneyFormat='#,##0.00 €;-#,##0.00 €';

SET TimeFormat='hh:mm:ss';

SET DateFormat='MM/DD/YYYY';

SET TimestampFormat='MM/DD/YYYY hh:mm:ss[.fff]';

SET MonthNames='Jan;Feb;Mar;Apr;May;Jun;Jul;Aug;Sep;Oct;Nov;Dec';

SET DayNames='Mon;Tue;Wed;Thu;Fri;Sat;Sun';

tabBookings:

LOAD RecNo() as BookID, *

Hi Manish,

Thank you for your fast reply. It should work great, but a weird thing is happening.

In the example posted by me, your script works fine, but using real-world data it shows one negative value for DaysBooked

I can not figure out where that can be

BookID	Occupancy	DaysBooked	Start	End

Provide sample data for two different BookID. One showing correct result and one showing negative. I will check and come back to you on this.
