Time Arithmetic
Apr 13, 2007
I have a cell (G11) whose format is [h]:mm to store hours worked in a week.
I need to use that in a VBA function. If I query G11.value I get a non-integer number (I DO know that Excel stores time internall like that). How can I get in a VBA procedure exactly what is see in the cell..e.g if someone worked 35:15 hours, I want to be able to get 35:15 in the procedure. I need to strip it from there to work out payment, eg (hourly rate * 35) + (hourly rate * (15/60)/100).
I have tried using format but it does not like the "[h].mm" argument.

The timesheet is for a night club, so people start late, and finish early. Therfore, in the total column I have the following formula...
=IF(D5="",0,IF(D5

Time arithmetic, I have two cells representing a time range.
The first one (say: X1) is formatted using the custom format [h]:mm and contains a certain number of hours and minutes. It gets its value by summing up other cells in the same format. A typical entry could be 98:35 to represent a duration 98 hours and 35 minutes.
The second cell (say: X2) is formatted as a number with 4 decimal places after the comma, and similarily gets its value by summing up other cells in the same format. It also represents a time duration as a number of hours. A typical entry could be 202.7500 to represent a duration of 202 hours and 45 minutes (because 0.75 of an hour is 45 minutes).
I would like to calculate the hour difference between these cells, and display it as hours and minutes. In the example given, the result should be negative, i.e. -104:10.
My first approach was to use the formula X1-X2 and format the result as [h]:mm, but this gives me a #VALUE! error.

I'm trying to put a simple spreadsheet together that will help my son practice
his arithmetic for primary school.
What I have put together is something which will allow him to change say his multiplication tables fairly easily by changing one number.
Conditional formatting shows green if correct and red if wrong - all very easy.
However I think it would be good to show the selected problem in a top down layout
so he can visually see what he is trying to do rather than read across the page.
4
x 2
==
8
rather than 4 x 2 = 8
What I would like to do is change this displayed problem when selects the answer cell
he is working on.
I will attach what I have done so far with a display example on the multiplication tab.

Is it possible to create a formula that would give the sum of cells that are in arithmetic progression in excel?
Example:
Let's first choose 4 cells that are in arithmetic progression, B14 , B20 , B26 and B32 for instance(the common difference here is 6). So what I want to do is: I want to type a formula in another cell, lets suppose C5, that will automatically give me the sum of the values of B14,B20,B26 and B32. I am aware that I can just type on C5 =B14+B20+B26+B32 but and if I wanted the sum of 90 cells? Wouldn't it be too much work to type all the cells? Does Anyone know a formula for it?

is it possible, in a function, to do something like this?
Lets say I'm in cell N7, and here's its formula:
IF (N6=$A$13,(A+1)$13,0)
-if the cell before it (N6) is equal to the value of $A$13, then I want N7 to equal the value of B13. If N6 is not equal to $A$13, then place a 0 in cell N7.
basically, I would like to tell my function to move to the next column if it meets a condition in an "IF" statement. Such as, go from column A to Column B given a certain condition. Otherwise, stay in column A until that condition is met.

Here is a very simple workbook/sheet with some simple date arithmetic.
I keep getting the warning that there's a circular reference in C2.
Either I need to suppress the warning so vba loops can run or PREFERABLY I'd get rid of the "circular reference".
Run with Excel 2013.

I'm trying to come up with a MapsCo grid to "overlay" geoLoc data. Given the coordinates of a single box within a MapsCo page, I'll can figure out the others once I know how to "from this point, add .5 miles due North and mark another point; from that point, add .5 miles due East and record the next point; etc".

I have a worksheet which contains START TIME in column A, then TIME USAGE in column B and END TIME in column C. User enters start time, followed by the number of time usage in minutes, how could i possibly display the end time automatically in this scenario? how do you add the entered time usage to the start time to display the end time? Say if I enter 1:00 AM at start time and 00:15 minutes on time usage, how can 1:15 AM be displayed on the end time automatically?

I am trying to provide a tool for department leaders to monitor productivity for order processing in their departments. The variables I have are: Number of orders(variable), number of pickers (variable), start time(variable). Then, I know each order takes 1 picker 4 minutes to pick on average, and there are 45 minutes worth of breaks during the picking process. So after entering the variables I used =(((C3*4)/60)/D3) to come up with the time needed to process the orders. What I can't get to is how to add this number to the start time, factor in break minutes and get to the projected completion time. I have Excel 2003 at work. Clearly I need to take a class!

I am looking for a function to convert time given by my computer (Local time) in EST (Eastern Standard Time). We are several users of a same file (with timestamp macros) and all time need to be aligned to one time zone (EST), even if all users are working in different time zone (EST, CST and IST).

Consider this code:
'light eligibility
Dim facb As String
Dim sunset As Variant
[color=green]' check if facility has lights[color]
facb = WorksheetFunction.VLookup(RID, ds, 10, False) 'find facility code
If WorksheetFunction.VLookup(facb, fac, 6, False) = "Y" Then 'facility has lights
sunset = WorksheetFunction.VLookup(tempws.Range("A9"), sun, 2, False) 'lookup the sunset time based on the record's date
[Code] ......
This code checks the need for lights at a facility.
It first checks to see if the facility even has lights by cross-referencing a value in the record with a facilities database.
If it has lights, it then checks to see if they are needed. If the rental goes past the sunset time, then it needs lights. Sunset is determined by cross-referencing the date value in sheet1! A9, with the sunset database.
If it needs lights, variable lghtson is calculated equal to "sunset"-30 minutes.
As I step through this code:
WorksheetFunction.VLookup(facb, fac, 6, False) = "Y" Facility has lights.
Check to see if lights are needed.
sunset = WorksheetFunction.VLookup(tempws.Range("A9"), sun, 2, False)
sunset=0.879166666666667 which is 9:06PM. This is a proper value from the lookup.
If rental_end.value > sunset Then
rental_end (value from textbox) = "9:30 pm" , sunset=0.879166666666667. This is true, and Excel accepts it as true ...
lghtson = sunset - 0.5
0.379166666666667 = 0.879166666666667 - 0.5 (9:06 AM)
This is not the value I was looking for. I was looking for 8:34PM (0.856944444444444)

I am trying to figure a way to search for a cell that has a specific date and time range. There are several cell titles pending on the activity. I want to find a cell that has a time ** 7:30-15:30 , 15:31-17:30, 17:31-20:30. The end result is to calculate the activity between those time periods based on the data cells.
Example
If the date searched time field ** the activity ranges is 1635 I need to split the time and credit the activity time in the 730-1530 time and the rest on the 15:31-17:30 time
I have been able to do it on a single labor group based on time alone, but when I try to add the DATE to it my numbers go null. Eventually i will need to add 11 labor groups daily for weeks at a time .

I have a workbook with macro button to run some vba, if i want the button to disable when the user make copies of the workbook (date created is later than original wb saved time) what codes to add in the VBA?
what i assume is to add the time to a cell when the wb is saved, when the wb opens, it check for that cell if the same with the date created, if different, then disable the macro button.

I have a protected worksheet. Users wish to be able to track changes in the input cells. The suggested approach for this is to temporarily disable sheet protection and allow them to change the font color, then protect afterwards. What I would like to do is:
i) check whether they are in an input cell
ii) if so, then prompt the user with the 'Font Color' dialog box
iii) apply the font color selected to the input cell
I'm struggling to find the dialog box I need. I can launch the one to change the interior color, no problem (Application.Dialogs(xlDialogPatterns).Show). But that's no use to me, I just want a color palette that specifically relates to the Font Color

I have a time column (A) that when looked in the cell only shows AM & PM times, but the cell itself (not showing) contains dates too, keeping me from be able to do a sheet wide sort of time or time frame occurrences.
Can I do some thing to sort these cells with their corresponding rows based on time only disregarding dates?
I am trying sort out all rows that in column (A) is time equal to or greater than 4:00 PM OR even maybe sort all rows that column (A) shows a time between 4:00 PM & 7:00 PM. The date in the cell is the problem, I think. Excel 2013

Refer to the attachment. I am trying to average the data in the Y column, if the times fall into the range between column R and S. I am having trouble with the averageif function. Is there a better way to parse through column W, check if the values fall between the ranges of S and R, and if they do, average the associated values in column Y?
