1) The output of an excel duration is : 22.00:8.00:25.00 ( day:hour:minutes ) - excel cannot average and work with this number format

2) resolution - =(LEFT(L2,4))+MID(L2, FIND(":",L2)+1,4)/24+MID(L2, FIND(":",L2,7)+1,4)/1440 as an array and Custom Format the cell as [h]:mm - works perfectly.

Q: to be conistent, the initial reporting is dd:hh:mm and then I convert to hh:mm so that excel can process the data. How can I convert from hh:mm to dd:hh:mm so that the excel report can be consistent in presenting the data to senior management?

Having trouble adding a column of minutes and converting the total into hours and minutes. Say Cell A1 through Cell A18 each have 12 minutes in each cell. I want cell A19 to tell me how many hours and minutes of total time that have elapsed. I have tried hh:mm, [hh]:mm, but nothing works.

We have a system called Datamart that outputs in excel formatted file.

The output of a duration is : 22.00:8.00:25.00 ( day hour minutes )

I want to be able to add, subtract, average, calculate the 10 fastest/slowests durations from a list of durations in this same format. I have googled and tried custom formatting but excel does not like this format. when I try to sum a range and divide by the number excel gives me 0.

I am trying to determine the total hours of downtime accumulated when there are 2 or more machines down during the same time period. To do this, I need to be able to determine if at any point there are 2 or more pieces of equipment down at the same time, and if this is true, how many hours were overlapped. The attached spreadsheet shows how the data is presented.

Any way to calculate the total hours staff work based on the mininum time of the first transaction to the maximum time of the transactions. I used a DMIN and DMAX function to get those times per employee. The issue is then the time goes over from one day to the next, such as from 11 PM to 4 AM the next day. As you can see in the data below,the fourth record shows the minimum time as 12 AM and the max as 11 PM with total time worked as 23 hours. In this example, the total hours worked should be five hours.

I have a column of tasks that take a certain amount of time to complete formated as h:mm:ss. I want to total the column and convert the total to days, hours and minutes. Is that posible and if so how do I configure a formula and format the cell? example:

I am currently trying to create a rota / rosta for work which will show people what hours they are required to work, in a format similar to below:

NAME | SAT | SUN | MON | TUE |etc > Person A| 8:00 - 17:00 | 13:00 - 22:00 | OFF | 8:00 - 13:00| Person B| OFF | 17:00 - 22:00 | 8:00 - 17:00| OFF |

This is simple enough to create but I also need Excel to calculate how many hours each person is working in a week and the total number of hours used per day and per week. I found out that I can do this using a formula to work out hours and minutes between two times. However what I would also like Excel to do is deduct the unpaid breaks which the person is entitled to, however this depends on the times that they work, i.e. in the example above Person A would be entitled to a 1 hour unpaid lunch on Saturday, a half hour unpaid tea on Sunday and no unpaid break on Tuesday. Therefore 1 hour would be deducted off the Saturday total hours, 30 minutes would be deducted from the Sunday total hours and nothing taken off the Tuesday.

I am working on this for two days , but I got stuck on the last step. I have a roster for about 35 employees. Calculating the daily hrs was not a problem. But I am doing the roster for one week. And I want employee wise total of hrs worked. I am quite confused as the "sum" formula works for some totals and for others it does not, although all the cells are in the right format. I tried to change the "result" cell to "number" and multiply by 24 to get the hr total as a number, but it does not work.

for example "SUMIF(E1:E57,"rafik",H1:H57)" ( this is the formula for calculating hrs for "rafik" on monday. the result cell is in "hh:mm" format and gives me the right total.

Likewise upto sunday the totals are right. What I want to do is calculate the total number of hrs from mon to sun. This seems to be impossible. the formula =SUM(H60:AL60) in a dd:mm format does not work, even =SUM(H60:AL60)*24 in a "number format" does not work.

I have tried "excel help" , tried to change the format but nothing works. The result should be 52 hrs and I cant get it no matter what I do.

I need to calculate the difference between two cells that are formated like this: 11/10/2006 13:00. Simple subtract only works when the date hasn't changed (the subtract formula seems to focus on the time and ignore the date).

I found a formula that will work, but the results are in regular numbers, I need the hh:mm format and if I change the format of the result column, the time displayed is wrong.

The formula is=((B2-A2)*1440)/60)

If my result is 122.6 in regular numbers, when I convert to hh:mm I get 14:00.

Is there a better way to do this? Also, is there a way to eliminate weekend & holiday hours from the calculation? This is not as important as getting the results to calculate correctly in the hh:mm format.

I have used the format [hh]:mm in a cell for 24 hr clock calculations. Why do I have to enter the numbers with a colon when I populate the cells? Is there a way to set it up so I just type in the four numbers and the colon between the hours and minutes populates itself?

For the past month now, I'm trying to calculate some work hours (night hours actually), based on a reference.

Let me show you the table:

- Column A has all of the schedules of the employees - Column B has the numbers of hours for each schedule (all have 8.5 hours/day) - Column C has the reference for the night hours.

Now what I'm trying to do, is to find a formula that will calculate the numbers of the night hours using the reference in Column C

Row 23 in that table has an example of what I'm looking for.

When I am converting a time from Hours/Minutes to Hours/Tenths, Excel is not converting it consitantely. EXAMPLE: 1:15 = 1.25. When I format the cell to present only one place past the decimal point, sometimes the cell will round up to 1.3, and other times it will round down to 1.2. What am I missing?

find a formula that will calculate the hours between the two below values but only take in to consideration the business hours (from 9 to 17) and exclude any weekends?

I want to add the numbers of hours in a 4 week period. I have used the following formula (from this site) to total according to month but I don't seem to be able to adapt it to change it to only add hours between 2 dates or for the 28 day period. I thought maybe I should be using a SUMIF but I can't get that happening either.

I know what to do when I add them- if the number is positive then a payment is due, if its 0 then the employer is "Up to Date" But what if they pay me more than they owe? I owe them hours, how can I have excel know that there is a surplus and to deduct the future hours worked from the surplus until i've paid it off?

I have my problem in an excel spreadsheet but I don't know how to upload so you can download it for reference.

I am trying to add together the total hours for a given week.The spreadsheet is used to show the total hours worked from the signing off and on times given.

CELL C11 CORRECTLY SHOWS THE TOTAL FOR ONE DAY AS 08:30 AND F11 AS 07:30. BUT WHEN THEY ARE TOTALLED IN CELL B13 IS SHOWS 1122:00 INSTEAD OF 16:00.

I have pivot tables where I need to look through a series of names and sum the hours and dollars charged by that person. When I try to do a pivot I can get it to read

column 1 Column 2 John Doe $4000 Mary Smith $ 500

But if I try to add the hour columns it breaks it out by the week the hours was charged

column 1 Column 2 Column 3 John Doe $2000 4 2000 4 Mary Smith $ 250 5 250 5

I want it to just give me one dollar total and one hour total per employee.

I am stumped on a formula answer I am getting on a simple timesheet. The timesheet is set up with an In and Out column for each day and person for the entire month. A formula calculates their total hours worked on a daily basis, minus their lunch (30 minutes per day). So far, so good.

The trouble comes when I try to sum the hours worked for the entire month. I am getting an incorrect total. The example I am working I am summing E3:BN3, which show the employee working 15 days in a month, 12 net hours per day. 15x12=180 hours a month. My sum total is showing up as 300:00:00. It may help to know we use a 24 hour format. I have the results cell formatted as [h]:mm.

I need to sum the total hours by project between two dates. There can be multiple projects and the two dates can vary. So...

In column A are the project # (say A2 001, A3 001, A4 002, A5 003) In column B is Yes or No for each project (contract Signed?) In Column C through Z, row 1, are dates (shows the Monday of each week) In Column C through Z, row 2-5 (which corresponds to the projects 001, 001, 002, and 003 above) are the number of hours worked that week.

On a separate tab (lets call it MonthTab) is the start and end date for each month (Jan through Dec) On a separate tab I want to SUM the hours by Month for each project (so for project 001 would need to go across multiple rows), that has a Yes in column two. Therefore the hours summed For January will be taken from MonthTab and be between StartJan and EndJan.
