Time Subtraction Formula
Nov 28, 2013I'm trying to do the following:
In the attached file, I'd like to subtract whichever is the earliest time between B4 or C4 from A4, then B5 or C5 from A5, etc.
I assume I need a conditional "if" statement but I'm not sure if that will work.

Time Calculations Subtraction And Average?
Dec 10, 20131st problem concerns entering data as text and it being converted to time. I have found the formula 00:00 which does an excellant job of converting. However, when I want to subtract, (=a2-a1) for example, it treats the time as a number. Sometimes it works, but if the hours are different, say 23:30- 22:10, it will subtract 2330-2210! Is there a way to make this work?
2nd problem, related to the first is when I try to avg a column of times, I get a similar effect.
Negative Time
Jan 30, 2007i am tracking my working hours at night, so i type in the time i start and the time i quit like this:
A 1 start B 1 end
A 2 22:30 B 2 02:30
now i want to calculate the time between.
but since excel don't like the negative time i got a problem. i figure i must make a function something like
=IF(B2<A1,B2+24)
i have tried a few but i don't get the parameters right so i get errors,
Negative The Time
Mar 8, 2008I have a formula calculating time to the second (e.g HH:MM:SS). I am calculating the difference from the time something was scheduled to be done vs. when it was actually completed. What I can't get Excel to do is calculate the same time but listing the time in negative, as if the project went over and by how much.
I know how to do this in numbers view, but unable to do this in time view.
Account For “negative” Time
Dec 9, 2009I’m trying to get the difference between times, BUT I want to account for “negative” time. So if I project that an employee will finish a task at 2 am, and they finished at 2:30 am, I want the result to be -:30, not just :30. If they finished at 1:30 then it would just be :30. Hence, my dilemma. I can get the difference, but didn't think Excel could recognize negative times. Right now I am using =MOD((A1-A2),1) or =(A1-A2+(A1<A2))*24/24 and in cells A1+A2 I am using military time.

View 2 Replies View RelatedTime Of Day As Negative Decimal
Feb 6, 2012Data from a SQL database represents time of day as a string of x's when imported into Excel. With CLEAN, I found that noon is -0.5.
This means that the calculation being used for noon is (24 * -0.5), or -12, meaning "go to the end of the 24 hour day, then go back half a day to noon." Similar calculations work other times of day.
Time entries that start in one day and end in the next are not allowed, so there is no problem with a change in day,
How can I convert this to the AM/PM time that my users need?

Dec 22, 2009(First please don't send me a link on how to subtract time or show Negative time. I know about 1904 ect.. I can't use that. I need a variation on the formula I am using if possible)
A1 I have a time
A2 I have a time
A3 I have a formula subtracting A2 from A1
The times will vary in A1 & A2. Sometimes A1 will be earlier or later thus giving me negative or positive times. I have a formula that will give me a correct answer but will always show either Positive or Neg depending on what I put in the last part of the formula "-H:MM or H::MM" =TEXT(MAX($A$1:$A$2)-MIN($A$1:$A$2),"-H::MM") in A3. I want it to do the subtraction but say if A1 is > than A2 then "-H::mm", If A1 is < A2 then "h::mm". I don't know if that is possibly or how to incorporate that into what I have.
Dealing With Negative Time Formatting
Jul 16, 2007It seems that time (i.e. -1:00) will be default as #########, etc. This makes me very unhappy. How to get around?
I could be fine with converting time to a total in seconds (i.e. 1:00 converted to 60 seconds)... but I'm not sure what kind of formula could do that.

In cell G1 i have formula to get time difference between cell C1 and D1 and its give me difference between these both time as 00:09.
Formula is =IF(OR(ISBLANK(C1),ISBLANK(D1)),"",D1-C1)
In cell H1 i have formula to get difference time between cell C1 and F1.
Formula is =IF(OR(ISBLANK(C1),ISBLANK(F1)),"",F1-C1)
But in Cell H1 i am getting Error as Negative time or date display as ########
Is there anyway where i can get Exact time diffrence between Cell F1 and Cell C1

Formula To Show Time In Hours Going Minus Instead Of Negative
Nov 4, 2012I have devised a simple formula when a member of staff enters a date and time into a cell it starts deducting from todays date and time. ie:
Cell A1 - Date and time is entered by staff
Cell B1 - Is the above cell +24hrs
Cell C1 - NOW()
Cell D1 - B1-C1 Formatted in hours ( [h] :mm:ss (Like a count down clock)
The problem i have is that i cannot get Cell D1 to show minus ours it just goes to negative and shows continous #####. Is there any way i can get Cell D1 to show the hours it has gone minus by.
Excel 2010 :: Adding Negative Time Values
Mar 16, 2013I have a problem with adding time values. The idea of my spreadsheet is to count time worked, and then calculate any variance from the normal shift length (i.e. 7h 30m). My formulas work fine until I work less than 7h 30m in a shift.
Example:
A1=start time
A2=end time
A3=IF(A2="","",MOD(A2-A1,1))
A4=IF(A3="","",(A3-(TIME(7,30,0))))
When the duration is over 7h 30m, A4 correctly returns the value of extra minutes. But when the duration is under 7h 30m the return is #####.
PS A1:A2 are formatted in a custom format hh:mm and A3:A4 are formatted as h:mm, and I'm using Win7 & MS Office 2010.

Subtraction Formula
Oct 21, 2009I have data that when added together will have decimals of .1 or .2. Any decimal great than .2 becomes an integre of 1 and is added to the other integres. for example: 1.1, 2.0, 3.2, 5.1=12.1.
I now want to subtract this total from another amount that will give me values with decimals of .1 or .2, example: 59-12.1=46.2 not 46.8. The same if 62-8.1=53.2.

However, I want to say 10 minus 12 minus 15, and thus return -17.

Oct 13, 2008cell A1 contains the numeric value: 3961.3
cell A2 contains the follwing: ="z equals "&B3-3933.7
which i would expect to give me: "z equals 27.6"
BUT, it gives me: "z equals 27.600000004"
which is awefully strange becos the 4 comes form nowhere...
what makes some sort of sense is that if the value in A1 is changed to 3961.4 or 3961.5, then the final decimal 4 in A2 changes into a 3, and then a 2.
when the value in A1 is changed to xxxx.7 the number in cell A2 becomes what one would expect it to be.
how do i get rid of these strange decimals???
(formatting cells, setting number of significant figures does not work. i naturally already tried that)
