Adding/Subtracting Times
Sep 8, 2009
I'm making a table for myself to keep an eye on my hours worked every week. What i want is to be able to enter the start time and the end time and for Excel to find the time difference inbetween (not numerical mathematical difference) also i need to subtract a half hour from the time entered for monday thru thurs.

Start time is 2300 in A1
End time is 0100 (the next day) in B1
Difference should read 120 minutes in C1
I know this is possible, I think I've thought myself into circles on something that shouldn't be hard. Everything I've tried is giving me negative numbers and at some point I've tried using the +1 behind B1 to represent the next day.
Here are some of the formulas I've found throughout various posts and used.
=B1-A1+IF(A1>B1,1)
=B1+(A1>B1+1)-A2
=IF(A1

I am making a timesheet
I have
Start Time, End Time, Break, Hours Worked. Then on the right hand side of my spreadsheet I started playing around with the current time etc.
I want to work out the time left in a working day(like a countdown), based on a variable number of hours of work in a day (here it is 7 hours) excl. breaksie. 7+breaktimeso I need 7+break - 'hours worked' to get hours and mins left
I worked out how to get hours worked easily enough,
=J58-LOOKUP(TODAY(),A:A,D:D)-LOOKUP(TODAY(),A:A,B:B)
where J58 is a cell that has the current time in it and D and B are the columns with the break time and start time in them.
Hours Worked01:59:48Current Time11:49:4807:00:00Break time: 00:30:0007:30:00
I am trying to subtract the hours worked (1:59:48 in this case) from 7:30:00. The hours worked can be updated every second using F9.
I know it's something to do with negativer times because of dates etc but I don't know what to do to make it work.

I need to subtract one cell from another. I want to subtract an input value (minutes) from a cell that contains a calculated value of hours & minutes. The calculated cell is custom formated h:mm. I prefer the input be a simple numeric value. The answer needs to be in the h:mm.

I am having trouble finding the difference between times. I have two cells, A1, A2. Times will be placed in there each day. A1 will have the first time and A2 will have a later time that day. i.e. A1 12:25AM, A2 2:45AM. A3 would have the formula. In this case I am looking for an answer of 2:00 (2hrs).
My second issue will be times when I have A1 11:20pm and A2 1:20am. I can't seem to get it to work.

Does anyone know why I get a type mismatch on the following? I am trying to subtract one time from the other to get the total hours worked.
Sub WorkedHours()
Dim vStart, vEnd As Date
Dim vHours As Integer
vStart = "11/09/06 22:00"
vEnd = "11/09/06 23:30"
vHours = (vEnd - vStart) * 24
End Sub

formula to work out a variance between two times
Using the 24hr time format in cell a1 i have a start time of 10:43 and in cell b1
i have an estimated time i think a job should take in this case 30 minutes and in cell c1 i have the actual time that job was finished in this case 11:07 and in cell d1 i have a variance between the two times which in this case would be saving me 6 minutes

I have the formula in my spreadsheet to compute time. It works only if the time in B1 is greater then the time in A1. I would to know if there is a formula to compute time with either negative or postive answer. For example if a carrier was set to load their papers at 12:02pm and ended up loading early at 11:50am I would like the result in C1 to be -12 or (12).
Currently I am using the formula: =HOUR(B1-A1)*6+MINUTE(B1-A1). Like I said, it is all good until someone loads early and then I get a "#NUM!"
Are there any other formula's that I can use or is there a simple modification to the formula I am using?

I'm having an issue with Excel. I believe I need to use a nested IF statement but I can't get it to work properly.
Starting Total = 50
Col A Col B Col C
20 IN 70
40 OUT 45
35 IN 80
What I am trying to achieve is if col B says in then add col a to the col c total from the line above, if col c says out then subtract col a from the row above in col c.
I have worked out how to subtract or add in seperate formulas but i cant seem to get it to work in the same formula.

I'm decently competent at VBA but no real experience with userforms. I have a very simple 3x2 table:
Type $Amount
Cash $xxxxxx
Product A $yyyyyy
Product B $zzzzzz
I want a simple userform that moves money between the products, ie the user selects a money amount in the form (ex: $1000) and that amount is added from one product and simultaneously subtracted from the other. Note that the amount selected would be subtracted from one product's current balance and added to the existing balance of another product. No new money is coming into the system.

I was wondering if it is possible to get the SUM function to:
1) Add numbers in cells that contain letters or no letters.
2) If there are brackets that cell would be subtracted from the total, again ignoring any letters.
For example:
A1 = 3 ABC
A2 = (3 ABC)
A3 = 4
3 ABC + (3 ABC) + 4 = 7

I have a percent 3.14%, that I want to show 15, 20 and 25% above and below that percent. I am showing below the results and then formula. The top calculation results in the same on both the left and right. However the -15,-20, -25% results are different. Which is correct.
3.14%
20% +/-
3.14%
0.63%
or
6.28%
1.57%
2.51%
[code].....
basic math, but I don't understand why the results are different.

I have forumlas that will look at this cell and take action of the month in a different cell is either 1 month greater (Frontmonth+1) or less (Frontmonth-1) than "Frontmonth". As we approach December I'm realizing that logic will breadown since the FrontMonth+1 would be 13, not 1 (January)
Is there a way to get excel to add 1 month to just the month number so that if Frontmonth = 12, Frontmonth+1 would return 1, not 13?

I've been trying to figure out a way to sum up a column of times like this (please see attached portion).
Right now, all the cells on the worksheet are formatted as text, and the "total" is actually a text value, not a formula.
I've tried converting all the cells from text to numeric, even tried custom formats like [h]:mm.ss to no avail.
What is happening for me is that when I try to sum up a column to get a total, the value gets converted or rounded off to zero (usually like 0:00.00).

I am trying to add a ROW of times. Each cell of times is using the 00":"00 format so I don't have to type a colon between the hours:minutes.
I'm not sure of what the formula should be for the Total Hours box.
For example, if I were to type 13:45 in the start time & 14:00 in the end time, I am getting a result of 0:55 which is incorrect
Another example if I leave the first 2 start/end boxes empty(blank) and then type 15:30 Start & 17:00 in the second set of Start/end boxes, I get a Total Hours of 1:70 which is also incorrect.
The formula I have in the Total Hours box is =SUM(B12-A12)+(D12-C12) which is know is incorrect.
What is the correct formula which will give me a Total Hours which adds a row of times correctly?

I have several columns of times in the HH:MM.SS format. I need a sum at the bottom of each column.
If I put a Sum or a Cell+Cell formula in, it gives me the #value error. I've tried a few different things but can't get it to work.
Could someone be so kind as to tell me the formula or point me to the instructions for this?
(The data reflects times spent on certain tasks for each day, and I need a sum at the end of each column giving me a total amount of time spent on that task for the month.)

I have a list a time (HH:MM:SS) that i want to sum together to get the total number of minutes.
It works if I use simply add A2+A3+A4 etc, but not when I use sum(a2:a4).
There are over 2500 lines of data.

I'll try to explain this the best I can. What I have here is a time study. Teachers (which are the control numbers) fill out bubble sheets, then I run them through a scanner. After dissecting the data from the scanner and formatting it to my liking i get this below.
Each teacher/staff member fills out three sheets per quarter. Each letter (bubble) counts as a 0:15 min period of time. Only K thru Q counts as billable time, which I've created a formula to count those letters (column 3). But to be countable each control number has to have three cycles 201,202,203.
So I need something that can take each control number that has three cycles and add their # of 0:15 together.
The italic row below only has one cycle for that control number, so that needs to be deleted or ignored.
Ultimately I would like the results on a separate sheet.
This is only a part of the file, there are over 1000 different control numbers.

In my workbook I have about 20 sheets (less in the attached sample), and on most sheets I’d like to query data for each day and find an average value based on the time and then copy that result into another sheet. I’m not sure if I’ll need 2 macro’s for this or if one can be used.
Here’s a quick description:
Assuming that I am currently in the sheet I want to run the macro, then I will either input “1:45” or “0:45” into a popup box, or I could always simply input the 1:45 or 0:45 in the code itself. I’m flexible
1:45:
If I input 1:45, then I’d like the macro to find the first 1:45 in Column B and the value in the same row in Column F will be used in the calculation. Once 1:45 is located, then the macro moves up to find 22:45 in Column B and the value in the same row in Column F will be used in the calculation.....

I'm looking for a formula that will calculate the difference in times between specific times while working with a 24 hr clock. Please see details below:
E3 provides the start time of 4:00
H3 provides an end time of 15:30
If an employee works betwen the hours of 0:00 (midnight) to 5:59, this is considered DIFF hours and is therefore the number I am seaking. So for the data noted above, the total DIFF hours worked is 2 hours.

Simplifying the following formula:
'=((F17-F17)*D17)+((F17-F16)*D16)+((F17-F15)*D15)+((F17-F14)*D14)+((F17-F13)*D13)+((F17-F12)*D12)
Its basically the sum product of column F time column D...however, all the F values are first subtracted from the last F value; Obviously I could just have an extra column to calculate all the new "F" values the issue with that is that I want to be able to drag down the formula and so the value F17 changes for each last value in column F...

I have two Ranges, which I view as Arrays or Matrices, I want to subtract the two (which do not overlap or union in any way) to get a new third range of the differene. This new range should be the same size, and can be considered a difference of each cell in the range. Note both ranges are already identical in size.
Any help solving this, searched up and down for hours.
Note; Im trying to avoid looping, as this might become incredibly inefficient if the ranges grow to big, looking for alternative that is faster, someone said maybe excel.evaluate

I have added a worksheet to a workbook, a co-worker will populate another worksheet within is workbook. The worksheet the co-work populates is a schedule. On my worksheet
I've set a possible units per day value, then pull from the schedule, starting from the top, the order that can be done in this time frame.
My problem is every so often in the schedule she will total the units in a cell (the units for each order are in one column and the total is also in this column, and this has to be this way for others in the plant). My formula checkes the sum of the units in this column, but it includes the cell that has the total units. This is the only cell that has a value in it on this row. I was trying think of some way to check the order number column for a blank, and if it was then subtract the value in the cell that has the units total in it.

I saw this answered somewhere on here but really didn't understand.
I'm trying to set up a sheet for my hours worked for the week.
I have the total per day in H2 through H6 In I2 through I6 I have an accumulative total for the days, so assuming I work 8 hours a day, I2 would be 8:00 I3 would be 16:00 I4 would be 24:00.
In J2 through J5, I'd like to have the weekly accululative worked hours subtracted from 40 so that the total is what I have left work until I hit 40.
