Subtracting Time
Feb 15, 2008
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.

Any way to enter in a total amount of time and then subtract it from a time shown. So for example:
I want to enter in a time of 26 hours, 10 minutes and 2 seconds: 72:10:02
I cannot find a format that allows me to enter the hours in excess of 24
Then I want to subtract it from a time of the day which will be entered as AM/PM: 02:40:02 AM
Then I want to show the result as a time of day: 00:30:00 AM
Lastly, I want to also show the amount of days adjustment: -1d, 00:03:00 AM
How this can be done through cell formulas?

I need 15 minutes removed from a difference in time, if the time span falls over 9:00 am through 9:15 am.
I'm inputting time like 8:30:00 in A1 and 10:30:00 in A2, then calculating the difference in A3 (2:00:00). Is there a way to remove 15 minutes from that 2:00:00, since it falls over 9 to 9:15?

I am trying to work out the response times to an event that my staff attend ( such as a fire alarm)
In C1 will be the time the event was called in, 23:55
In E1 will be the arrival time, 23:59
In F1 I want to show the time taken to arrive on site (response time)
This seems straightforward until the arrival time goes into the next day, such as 00:05 and this is when I have the problem
To make it more complicated, sometimes there is no need for an arrival time to be entered for some events ,with the end user leaving it blank or putting "NA" or "na" etc into the cell
I have tried the below formula which works to a point but leave me with an ######### error if the time is after midnight
=IF(E1="NA",0,IF(E1="n/a",0,E1-C1))

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 have some intraday date that looks like this, hope the formatting comes thru when i post this....anyhow, the second column is TIME (ie 15:25 15:30, etc...5 minute time intervals for SP500 stock data. I want to have a column that simply subtracts row 2 column b (time column) from row 1 column b.....when i do this i get a #value....I know this must be possible to get a result i need....ie 15:30 - 15:25 = 5
Do i need to reformat the TIME column into something different? ....

In cell L7 I have (80/60)/24 and formatted h:mm to get 1:20. In cell M11 I have 1:00 (h:mm). In cell M12 I have L7-M11 and get the result 0:19. Why I'm losing a minute and not getting the result 0:20?

I have a working week that starts at 07:00 on a Monday morning and finishes at 14:30 on a Friday afternoon.
For planning purposes I need to know at any given point how many working hours are left. The reason for this is so that I can multiply that figure by the amount of Engineers available which will give me the amount of Man Hrs left in the week.
For example - if it is 11:00am on the Tuesday, how many working hours are left ....

How can I add/subtract time entered as 1830 to give a decimal value?
Start=1830
Finish=2000
Time between = 1.5
Also, how can I convert time as 1830 (24hr) to 12hr time? ie. 0630.

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.

My challenge is discovering the difference in time between two rows of data that is imported with milliseconds in the time slot. In my example below I would like to see how I can subtract the time listed in line 4 from line 3 (11:18:59.566 - 11:18:59.550). When I try now I get either 1.85185E-07 or 00:00.0 or 0.000000 depending how the cell is formatted.
2012 02 17 11:18:59.050|081,999999999999~999999999999
2012 02 17 11:18:59.550|082,MCTO05222CZ0~999999999999
2012 02 17 11:18:59.566|082,1
2012 02 17 11:19:00.144|083,MCTO05246CK0~999999999999

I am trying to subtract 12 business hours from a date/time stamp. It has to be during working hours however which are 8AM - 5PM, Monday-Friday.
For example if my value is 6/23/2008 9AM
Subtracting 12 business hours would give me 6/19/2008 3PM.

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

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.

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

What would the formula be for subtracting two dates to get the numbers of years, months? I cannot get my formula to work.
Also, can Excel take a telephone number such as (555)-555-5555 can place the phone number in another field such as 555-555-5555?

I am tryinig to use an if statement but I don't have it correct. If columns E, F, and G are not null I want it to subtract 3 from the Total column. Right now it is subtracting from G.
Sub SubtractPoints()
Dim I As Long, subpoint As Long
With ActiveSheet
subpoint = . Range("h65536").End(xlUp).Row
For I = subpoint To 2 Step -1
If Not .Range("E" & I) = "" And Not .Range("F" & I) = "" And Not .Range("G" & I) = "" Then
.Range("H" & I) = "=RC[1]-3"
End If
Next
End With
End Sub

I have a total number of hours I want to subtract from. Example in cell e3 I will have 800 hours. In cell f3 I have the number 2 (to represent 2 workers at 40 hours, so that should total 80). I then want f3 to multiply by 40, then that total subtract from the 800 hours in cell e3. Basically I want to be able to put 2 workers in a cell, have that multiply by 40 and minus from the 800 hours in cell e3. I want that to carry on for cell g3, etc.

I'm trying to program a spreadsheet for staff attendance at a school. In the spreadsheet the staff member has personal days, sick time, and sick time in the bank (sick time rolled over from last year). When they use sick time, it needs to come out of the bank first, until it reaches zero, then it should move on to the sick time accumulated for this year.
Staff attendance WIP.xlsx
On the left side is the staff name, sick time, personal days, and bank. Then are the school days for July (if a staff member uses sick time/personal day it is placed under the date it was used). On the far right is the total remaining amount that the staff member has left.
The formula I have for cell AF4 is: =MAX(0,G4-SUM(H4:AC4)) so that the cell will not go below zero.
The formula I have for cell AG4 is: =E4-(COUNTIF(H4:AC4,"P")+(COUNTIF(H4:AC4,"HP")/2)) So that when P for personal day is entered, it will take a whole day, and when HP is entered a half a personal day is subtracted.
I need to figure out a formula for cell AD4. I've tried a couple of formulas I've seen on other posts, but they weren't for a series of numbers like this. And when I put them into this particular spreadsheet, it would subtract the bank until zero, move on to the 'sick time' cell and subtract the SUM of all the days sick rather than subtracting what was left when the 'Bank' reached zero.

Is it possible to subtract a number from a column letter? I'm trying to create a sheet that does some helpful calculations. In order for me to finish it without a macro i need to be able to subtract a number in a cell from a column letter. Example F-5=A, The end i'm trying to achieve is to get a sum range to move left and right in this data set based on that number.
