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 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.

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?

The below formulae allows me to see the difference between two dates and only returns the difference in working hours ie : Difference between 02/02/2010 08:00 & 03/02/2010 08:00 is 16 Hours 0 Minutes

=(INT(A3)-INT(C6))+MAX(MOD(A3,1)-MAX(MOD(C6,1)))

The following displays it in the Hrs and Mins format

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.

Is there a method to calculate the total number of hours in excel. In my attached file, the excel treat the 24 hours as time and recalculate from 0 hour.

Refer to the attached sheet which is Daily Schedule for employee. I need a formula to add hours worked on single day in cell C2 for Monday, E2 for Tuesday, G2 for Wednesday, and so on.

Every day we have Clockin_Clockout info for each employee as shown for employee a & b.

FYI : I am using below formula to add employee hours for the week as (formula in cell R4).

This is probably a very simple problem that has me going around in circles. I am attempting to set up a time roster, where I simply want to check:

If "end-time" minus "start-time" is greater than 4:00 (hrs), then deduct 00:30 (minutes) and place that result in another cell.

If it is not greater than 4:00 (hrs) then leave unchanged. I have read thru countless examples on the Forum - but I think that such great learning is driving me mad. Although I do believe that I have the correct format [h].mm - but attempts with IF's have got me confused. This is one of those "Looking down the tunnel towards the flickering light" moments.

I am using a formula such as =Text(A5-E5,"H:MM) to get the difference in clock-in time and clock-out time on a daily basis (Monday-Saturday). I want to add the results as a total for the week. I am not sure what formula to use to get that result. I prefer not to use decimals unless I have to. Also, the above formula does not work when the time goes past 12 midnight.

I'm trying to figure out what is wrong with this formula. =(SUMIF(Q14:Q4995, "<="&EOMONTH(TODAY(),0),W14:W4995))-(SUMIF(Q14:Q4995, "<="&EOMONTH(TODAY(),-1)+1,W14:W4995)). I've got a cell that adds Total hours worked which pulls from the same column of entered data as the formula above and that cell works. My hours for the month however just shows up as zero. If I try and edit the formula or even just highlight it to copy it and then tab out of the cell this shows up...

1/0/00

If I undo the highlight and tab it will go back to showing zero. I've checked my dates that I entered and they are correct. I'm at a loss as to how to fix this formula.

I want to find out how many hours, in total, relate to "consolidation 1, 2, 3; Lease Renewal 1,2 3 etc. What formula can I use. I am working on a "sumif" but it's not working out for me. Hours 1 Consolidation 4.75 3 External Sublea 3 Consolidation 2 3 Special Project 2 External Sublea 1 Lease Renewal w 1 New Lease w/o T 4 1 New Lease w/o T 1 1 External Sublea 3 Lease Renewal w 1 2 Lease Renewal w .5

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.

how to roundup and total time using formula? specifically with the format mm:ss:0? i have 3 columns with these formats and would like to add them up but can't seem to get the right formula.

I have a base of workers which log each day their activities in hours (D01-D11). I would like a macro to sum total hours of each project (project numbers are from 320-516) and put it into the table on the left.

For example: For PERSON 1, I want that the cell I60 writes 10, and cell I74 = 6. For worker 2 (PERSON 2) would be AK60 = 3,5; AK67 = 8 and AK74 = 8.

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.

I have a base of workers which log each day their activities in hours (D01-D11). I would like a macro to sum total hours of each project (project numbers are from 320-1500) and put it into the table on the left.

For example: For PERSON 1, I want that the cell I60 writes 10, and cell I74 = 6. For worker 2 (PERSON 2) would be AK60 = 3,5; AK67 = 8 and AK74 = 8.

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.
