Hi i’m new here. Trying for days to make my app work. It look so simpel in Excel but really need some help.

I want to use a time picker for begin and end time.
Also a time picker for a lunch
Of course I want a column with ‘total worked hours’ and a column ‘without lunch’.
Than the total worked hours must be rounded on 7:26 to 7:30

But I’m stuck. I’m struggling with time and decimal time.
I don’t know why but when I use (eind - start)*24
he also calculate lunch with it.

I think before we address the math formula problem, let’s talk about how we get the inputs. This is assuming you will get the inputs from Glide, not an external service.

It must be noted that you won’t be able to catch only the hours & minutes of your start, end & lunch parts using a date/time picker.

I think your start & end columns should be written to by two date/time pickers or an event picker, but it will go with the date alongside the time.

Your lunch column can be written to by a stopwatch, or you can try an alternative by letting the users input the number of minutes they used to have lunch.

Yes: the input is from Glide with an event picker.

“I think your start & end columns should be written to by two date/time pickers or an event picker, but it will go with the date alongside the time.” OK

Then my preference would be to let the users enter the number of minutes they used to have lunch.

To answer your original question, I formatted all my examples as I said above, timestamps for start & end, numbers representing minutes for lunch time.

The “without lunch” column calculates the total time without lunch, no rounding here.

E-S-L/24/60

The “total time” column rounds up to the nearest 30 minute.

I’m going to process it in my Glide. At least now I know where to look and that some things I had come up with are not possible. Thank you for your time and super quick response.

Maybe I’ll eventually have a question with the totals per week. But will try that myself first.

I’m not in front of my computer but I think you should convert your date column to a number then set the corresponding number then put it back to date… or something like that… I seem to have done that before.

OK. I’m guessing @ThinhDinh is probably sleeping now. I’m not by a computer right now to try it out either, but I’m sure one of us will get back to you when we have a chance.

You are all great! As long as I know it’s possible I’ll keep trying. @jabid Thank you for your tip! Let me try that. But if you’re faster, I’d love to hear it.

Yes, this does indeed look better. Thought I had already tried every possible way. But now there is indeed the possibility to round down. 09:46 > 09:45
