Negative Times

Dec 22, 2009

For simplicity sake I will put what I have in close proximity cells and what my issue is. I am taking a number A1 (7.7) and turning it into time A2 =A1/24 (7:42)

A3 (18:00) Which is our work start time. I am taking 7:42 min estimated work day hours and adding that to our start time of 18:00 for A4.

A4 =A2+A3 (1:42) This tells me that we should get done around 1:42 am

A5 I enter the actual time we finished. Let's say (2:23)

A6 =TEXT(MAX($A$4:$A$5)-MIN($A$4:$A$5),"-H::MM")

This gives me an answer of (23:19), but if I type over the formula in A4 (1:42) which is the answer to the formula and already has that number there, I get the answer (0:41) in A6 and that is the answer I want. I can't figure out why I can't get A6 to give me an answer of (0:41) with a formula in A4. I even tried having another cell formulate A4 and then A4 =that cell and it is still the same.

Display Negative Times

Jan 5, 2009

I am doing math on times and want to be able to SEE values of Negative times instead of the ########. This is happening in a time card because I am summing the weeks total and subtracting 20 from it (expected 20 hours per week) so it will ALWAYS be negative until the last day of the work week.

Negative Times To Read Zero?

Sep 20, 2012

I have a spreadsheet that I have combined the HH/MM/SS into one column and formatted it as time. If the numbers are negative then the - comes with it into the new column. I want to create a new column to calculate the negative numbers as zero and leave the positve numbers as they are.

Here is the formula that I used to combine the columns:

=TEXT(O322,"0:")&TEXT(P322,"00:")&TEXT(Q322,"00")

Formula To Make Product Of Two Negative Numbers Negative

May 12, 2009

I have a large dataset (24000 rows) that requires me to multiply two different columns of integers. In some cases, the two integers are both negative and multiplying them results in a product that is positive. I actually need that product to be negative rather than positive. I can't quite seem to figure out the best way to accomplish this.

Convert Negative Numbers With Negative Sign On Right

Aug 1, 2007

I have data that comes from a subsytem that places the negative sign at the right of the number, so it is recognized as text. I can get around this using find and replace and then a second step to multiply that by -1, but is there a formula that can do this for me?

I was trying if(right(A1,1)="-",TBD,A1)

Positive To Negative If Cell On Left Negative

Sep 1, 2007

I have data starting in E7. I want it to go down the column and find the negative numbers. If it finds one then I want it to change the number in the row to the left of it to a negative. So if E67 is a negative number, make D67 a negative and so forth down the line Sounds "simple" but how do I do it?

Macro Loop – Find Specific Times, Extract Date, Average Values Of Times

Feb 23, 2010

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.....

Excel Formula To Calculate Difference In Times But Only Between Specific Times

Apr 8, 2014

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.

Count Times Between 2 Specified Times

Sep 15, 2006

I thought I found a formula that would work, but it's not working. Each month I have to count the number of service tickets that have arrived between certain time ranges. They want to gauge during what times we seem to get the biggest batch of service requests.

6 am to 10 am
10 am to 5 pm
5 pm to 6 pm
6 pm to 6 am

The format of the cells are:

1:21:19 AM
1:28:08 AM
1:35:48 AM
1:49:19 AM
2:17:02 AM
7:14:38 AM
7:29:12 AM
8:08:28 AM
8:51:48 AM
8:54:19 AM

The formula I tried for 10 am to 5 pm: =COUNTIF(B2:B677,">="&TIME(10,0,0))-COUNTIF(B2:B677,">"&TIME(17,0,0))

It gives a result of 676, and I know from manually counting that there is only 327 cells that have a time between 10 am and 5 pm.

Negative Time

Jan 30, 2007

i 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,

IF AND With Zero Or Negative Number

Mar 9, 2013

I would like to add to this formula.... if the result of "$L$6-Q15", from below, is 0 or a negative number, then the desired result would be 0 for this formula.

Possibly wrapping IF AND somewhere in this...

=IF((O15+(K16*$L$5))>=$L$6,$L$6-Q15,K16*$L$5)

Look Up First Negative Number

This may sound simple, but is not (it might be easy for you hopefully)...... I have a string of numbers and the first few numbers can be either postive, negative or zero....Later on, the numbers all become negative......

I need to find the the cell which contains the first negative number in the consequtive negative numbers.....The difficult part is the numbers before the consequtive negative numbers can be anything......

Negative Number

Jan 2, 2008

is there a way to format a cell that will make the number a negative number regardless of what number I type; whether I type a positive or negative.

What i'm trying to accomplish is enter a number and the number will be negative. I don't want to have to type a negative in front of the number.

Negative The Time

Mar 8, 2008

I 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.

Negative Minutes

Mar 10, 2008

I have, on some occassions, negative minutes e.g. -125. I have a formula in a separate column which divides the minutes by 1440.

Hence I could have

AE AF
Session Minutes Session Time
210 03:30
-125 ############

Column AE is General format, whilst column AF is Custom i.e. hh:mm.

How do I rectify the formula AE2/1440 so that I get the Session Time to work but with a negative sign?

Sum Negative Values IF

Dec 11, 2003

Using Excel 97, Is there a way to Sum the values in columns if the value in cell B is a negative number. I want the total placed in their respected columns after excel finds 8 Consecutive Blank rows.

Ex

B1:B70 (remember the number can change it can also be B1:B80)

B1:B70 is a positive value, but then B85 is negative so begin the calculation from that point.

Sum B85,F85,G85,H85,I85,J85,K85,L85,M85,Q85,R85. And place the value in their corresponding cell after 8 consecutive blank rows appear in row B.
