A little simple program - calculates the days beween two dates.
Code: (Select All)
'Differenz zweier Datumsangaben ermitteln
WScript.Echo DateDiff("d", Now, "1.4.2024") & " Tage bis zum 1. April 2024"
![[Image: Datumsdifferenz2024-03-04.jpg]](https://i.ibb.co/W3zkvSm/Datumsdifferenz2024-03-04.jpg)
Just add to your program and calculate differences, leapyear, weekdays, daylight saving, timezones, etc.

Quote:@mdijkens - You can do these and other date/time related things very easy with the library I posted above.Thank you for your hint. The key point about "DateDiff" is, how should I use that for calculations?

I know "DateDiff" from VB-Script and from Visual Basic, and there I used it for calculations in financial programs. I was able to use the result of “DateDiff” when calculating the repayment amount of loans.
Back then, I recalculated all formulas and results in all programs using a calculator, and when "DateDiff" was used, for example, it always delivered a correct result.
There can't be even the slightest mistake in finance. . . otherwise the Third World War will break out.

I myself use vbscript for a ton of things on Windows, but I do like knowing my programs can work on those other OSes. So if someone wants to write some native QB64PE date functions that are multi-platform compatible, I can see the value.
Along those lines, I would imagine that much of the commonly used date functionality has been written before in GW Basic, QuickBasic, in VB 3-6, etc. Or any procedural language that can be ported over to QB64. It might be helpful if they can be updated to work with QB64 (or to learn from).

I'm not a developer, but this feature would be worth integrating into QB64.
One don't have to redevelop it for QB64, just create a way to integrate it. You enter a start and an end date, pass it to "DateDiff", and get the correct number of days etc. in order to be able to use this result further.
This function would not have to be reprogrammed for this.

I do think it would be useful if QB64PE added a native DateTime type like in VB6 / VBA / VBScript, with datediff and dateadd functions, but I think epoch should be able to handle most cases?

Quote:For something like DateDiff, if you convert the date and time units to UNIX time / epoch in a common time zone, isn't it just plain addition & subtraction? Then you just convert epoch back to standard date?Now I'm stumped. All I remember is that between 1998 and 2001 I created programs that enabled financial calculations on websites. That was intentional.

Since only IE was used internally, I was able to use VB Script without any problems. But I also used Visual Basic 3.0 Prof for corresponding programs.
Long time ago.
