I'm building a schedule in excel and am having trouble with the calculation of total hours when lapsing a day, or more specific, adding it into my current equation. For example; Monday they clock in at 5pm and work till 1am. I have found a couple of ways to get the desired out come from this on it's own. I just add the value of a day if the out time is less than the in time, or if the out time minus the in time is less than 0.

However, I need to add this calculation into an equation that is already calculating time elapsed within a single day, turning that into a decimal number and then checking if the total time elapsed is less than 6 hours, if false it subtracts a thirty minute break. Here is the current equation I'm using, I'm sure that there is an if(or, or if(and I could use to make it work when the time lapses 12am while also performing the 6 hour check to subtract the break.

I am trying to calculate the time elapsed. I have included a caption to show my formula. The problem I have is that some times are showing > 60 minutes instead of increasing the hour. When my day go over the midnight hour I get a negative number.

I have a start date dd/mm/yyyy, and require a formula that everytime a spreadsheet is opened, based on the current date, to calculate how many years, months and days have elasped yy mm dd since the start date...

In our sql server table, we have a field of type DATETIME. This field is populated by a vendor product with the elapsed time of an event.

We created a SQL Server view of this column and other columns of info joined together from several tables.

Then we create in Excel 2010 a new spreadsheet with a data connection to the SQL Server, instance, and view that we created.

Excel 2010 displays each of the columns in our view.

The elapsed time column appears as "dd hh:mm:ss". However, when we click on a cell to look at its formatting, Excel lists it as general.

We want to calculate the average time in this column.

We go down below the data, click on a cell, and insert =Average(C2:C17215) and we get an error saying dividing by zero.

We have 17,000+ rows of data, so there is no divide by zero math going on here. Each row in this column has data, so there are no blank cells.

We have spent some time web searching. We then tried various methods of calculating this. Nothing has worked. In most cases, we get the divide by zero. We tried some solutions that mention using an array forumula, but that just changed the error to an invalid value error.

If a Rescue Officer is called out at 23:00 and is back at 04:00, this should equate to 5 hours worked.

It seems that if my times are all on one side or the other of a 24 hour cycle, my calculation work fine but it it breaks across the 24 hour (as above, it doesn't work.

A2=04:00 A1=23:00

Using (A2-A1)*24 give me -19.00 hours

My SS macro has a line:

s = (wks.Cells(c, 3) - wks.Cells(c, 2)) * 24 'calculates the duration of time worked

Is there any way of getting excel to calculate an elapsed time in hours when the start and end times roll over from one day to the next?

I am using the following formula in Column E to calculate the difference between an employees start time, and their previous shift end time in order to work out how many hours rest they have had:

=IF(A4=0,"",IF(I4=0,"",MOD(I4-B4,1)))

My Current Formula works fine for same day calculations, but if an employee finishes work at 18:00 on Friday and starts work at 22:00 Saturday night, Excel calculates the Total Rest hours as 04:00, when in fact they have had 28:00 hours rest...

Is there a way of calculating the hours difference between two dates?

I have attached a sample of my spreadsheet to illustrate

In one column I'll have a list incrementing in 1w,2w,3w,1month and I want to be able to count the number of days that have elapsed till the latest cell. Right now I'm just winging it by saying there's always 31 days in one month using a COUNTA function, but I need it to be accurate.

I am not sure that I can do this, but here is what I would like to do. I have a worksheet that I initial when I start a job in on cell and then when I finish in another cell. What I's like is to have a macro running in the back ground that will tell me the total elapsed time from when I started to when I finished.

I am trying to create a time stamp that shows elapsed time. So I enter my start time, and if I enter any text in cell B7, return the elapsed time in A7 based off of start time in A6. I have attached an example workbook.

I am trying to get the number of hours elapsed between these 2 dates and time

6/28/2009 9:14 4/26/2009 8:05

this is the format it is imported as is there a way of getting the number of hours and minutes between the 2 i have tried a number of formats but once it gets beyond 24 hours i can't get the correct result.

I have a document in which I am trying to determine the length of time between a start date & time and a finish date & time. The format of the time/date cells is

mm/dd/yy hh:mm:ss

Basically, I am just subtracting the first cell from the second. This works fine as long as both dates are in the same day, such as

the ELAPSED cell fills with ######## with a tooltip stating that "dates and times that are negative or too large display as ######." The actual result in this example should be 1:03:07.

How do I get consistency amongst my resulting formulas?

I am trying to determine the amount of off duty time from the last stop time to the next start time. The object is to reset another column of hours (not shown here) to 60 hours only if there has been 34 hours of off duty time prior to the next start time.. I have posted this problem previously but did not explain very well I need to accomplish. The start and end times ( E & F) are formatted as hh:mm AM/PM and the Work time and the other columns are formatted as [hh]:mm. Where my formula fall short is when there are blank days indicating weekends or days off ...

I am trying to find some simple code that will display elapsed time starting from execution of a macro to a certain point where a message box is displayed at which time the elapsed time should pause awaiting user interaction. Once the user has responded to the message box prompt the timer should continue on from its paused state ceasing at the end of the macro. I would also like the displayed box showing the timer to remain visible displaying minutes and seconds and continuously incrementing even though screen updating is turned off within the macro. (The macro switches sheets a number of times) and the elapsed time box needs to positioned at bottom left of screen.

How to find the elapsed time between two times, but I need the start time in this instance.

Attached is my spreadsheet for a callcenter in which has exported data showing what time the data is exported and how long someone has been their state if they are out of adherence. I have selected fields explaining what I am wanting where on the spreadsheet.

I am wanting to subtract the elapsed time in MM:SS from the End Time which is in HH:MM AM/PM (Imported as text). I do not mind moving these to separate cells to the left to format them correctly, I want to be able to right click in A1, paste, and the rest trickle.

I am having difficulties subtracting the time to get the start time.

I would like to develop code that does the following:

- I first manually move to a cell - Press a key combination (CTRL+T for example) - Press the same key combination, the elapsed time from the first press to the last press is entered into that cell in seconds.

It would be nice if the cell showed the time incrementing live, but that is not required.

I have a worksheet with checkboxes in each cell in A11:A110 as well as O11:O110. When a checked, the current time appears in the corresponding cell, using this code for example, A11 :

This system is used to track time elapsed. Example, the first event of the day begins, so I click the checkbox in A11 and the time appears in A11. When the event ends, I click the checkbox in O11 and the time appears in O11.

Now what I would like to modify is the following:

After clicking A11, if 30 minutes have elapsed and I still have not checked the end time in O11, I would like the whole row to highlight in red, a pop up message box should advise me that 30 minutes have elapsed. I could click OK and remove the message box. The whole row remains in red highlight until I finally check the checkbox in O11.

Obviously I'd copy the code for each row.

I assume the code goes with the checkbox's code for A11? Also, is it possible for a cell to flash? (highlighted white, then red, then white, red, etc...)

Setting up a worksheet to monitor bookings within a time range of 06:30 to 09:30 then from 14:00 to 18:00. The data is collected in the following ranges. E3:E25 M3:M25 E29:E60.

I need the data collected from 06:30 to 09:30 - deleted JUST before 14:00 Then need the data deleted again JUST before 06:30 the next day.

how I can save the elapsed time between when a cell is clicked on? Example: Click on cell A1 to enter a number – three days later click on cell A1 to enter another number. The results would be 72 hours lets say in cell F3.

I have an assignment to audit the time it takes convert a printing press from one job to the next. I've been using a watch to take the readings in hours, minutes, and seconds.

I recorded them in my spreadsheet, as h:mm:ss, but it showed a date also. I think I finally got that resolved, but now, when I try to subtract one time from another time, I get an incorrect answer. I think I need to convert all of these times into decimals, as in 13.23.44, as oppossed to 13:23:44.

One post on page 1 of my search said to multiple A1*24, but I don't fully understand. I tried that, but 11:30 became 11.50?

I need to extract the set up time, or job to job changover time in a decimal format if possible. There are other tasks being done with those numbers later in the spreadsheet that are more conducive to decimals, than the time format.......

I'm trying to write an if statement to find the elapsed time. I want it to work so that if a time wasn't recorded, it looks to the previously recorded time to find the time in-between.

The problem I have when testing this formula is that D18 is not blank, so it should calculate (F18-D18)*1440. But it's not.. it's calculating (F18-N17)*1440. Here's a preview of my spreadsheet.

I have been trying to get excel to calculate elapsed time between two dates using mostly what I've read from other elapsed time posts. But I am clearly missing a step. I'm trying to streamline my process for taxes.

I want to take a time in the format of " yy/mm/dd hhmm " example: 1

3/04/24 2245 ( note its a 24hr clock) 13/04/24 2245 would represent 2013 April the 24th at 10:45PM.

------- A --------------- B -------------------- C 13/04/24 2245 ------13/05/24 0900 ---------[display hrs elapsed] <-- currently get #name?

I have custom formatted A and B to yy/mm/dd hhmm and formatted c to [h]:mm

When you enter b-a in column c you get #name?

If its easier to have the date and time into separate columns I can give that a shot, I was just trying to make it as streamlined as possible for copy past.

I have been asked to make some ammendements to a workbook currently in use.

I have to calculate elapsed time, and my formula is giving me odd results. I have a start time (cell B5), and an end time (cell F5). The formula being used was =IF(F5>0,((F5-B5)*24)) which gave the correct result. The cell is formatted as general. It didn't alot for the situation where the end time has not happened yet.

I changed the formula to =IF(F5>0,((F5-B5)*24),(K5-B5)*24) where cell K5 is the current time. The results are coming out with 6 - 9 decimal places. It makes no sense as I've tried setting the times to be exactly 24 or 48 hours to the minute. I've also tried replacing K5 in the formula to now(),

I am trying to build a spreadsheet to calculate how many hours have elapsed between to entries; start time (H10) e.g. 9:15 AM and end time (I10) e.g. 12:15 PM. The formula that I am using in the calculation cell field (J10) is (I10-H10+(I10<H10))*24. This formula works great till I wish to include in an IF statement. What I would like is if the total hours calculated with the formula (I10-H10+(I10<H10))*24 is less than 4, return 4 (hours) otherwise the value. As well if there is no start time nor end time entered then return zero.

I need to calculate the time elapsed between start and finish dates. I've figured the TODAY function, as explained here but I'm referring solely to dates in cells. How to?
