# Subtracting Hours And Minutes

Jun 10, 2013
I am trying to calculate employees hours of work from information provided to myself.

Each employee is contracted to work 40 hours per week. The information provided to myself is in the format - Employee has worked 39.30 This is in fact 39 hrs 30 minutes. Obviously when I subtract 39.30 from 40.00 I get 0.7 and not 30 minutes. I tried formatting the cell containing these figures to hh:mm but it comes out at 15.30 & 15.00 respectively because it is over 24 hrs. How do I convert the digital number (0.7) to minutes I.e. 30 minutes.

I have tried to convert the 40 hrs into minutes but because the hours are greater than 24 then I struggle.

I have a spread sheet with a colum showing average time to complete a task. This is currently shown as Days:Hours:Minutes:Seconds (4:19:33:19). I meed it to be shown purely as minutes, or at least as hours and minutes.

I have a formula which will calculate the number of hours and minutes between two military times. I would like it to calculate the total number of minutes instead of hours and minutes. I have uploaded a small example of what i have so far.

I'm trying to convert 3786 minutes to day:hours:minutes. So divided it by 1440 which is 2.63... but I want this displayed in the worksheet as 2 days 1 hour and 3 minutes (02:01:03), I just can't seem to get it to work and it seems quite simple... but I'm missing something.... I was trying a custom format like dd:hh:mm or [d]:hh:mm and I was also trying a convert function and =day/1440+hour +minute

I need to subtract one cell from another. I want to subtract an input value (minutes) from a cell that contains a calculated value of hours & minutes. The calculated cell is custom formated h:mm. I prefer the input be a simple numeric value. The answer needs to be in the h:mm.

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?

example attached.

I am working on a monthly employee work schedule that has 2 stores. All employees work at both stores and the boss wants 2 separate schedules.

I have attached what I have started, which at the moment I am stuck.

I would like to have the Row 5 total hours to always reflect (subtract) a 30 minute lunch. I know it would be easier to have another column, but the boss wants it this way,

I also need the total hours in column H to reflect the total of each day (with the subtracted lunch break). In this column I am having the figures turn red if over 40 hours and green if it under 40 hours.

With having 2 stores with the employees working at both, I need to somehow have the hours of the employees add up from one store to the other (a running total, if you will).

Lastly, if I have an employee not scheduled for a day or need to put other data such as, VAC, HOL or blank cell etc in a cell, how can I get this to work and not have the formula go nuts when it is not in a time format.

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 trying to subtract 12 business hours from a date/time stamp. It has to be during working hours however which are 8AM - 5PM, Monday-Friday.

For example if my value is 6/23/2008 9AM

Subtracting 12 business hours would give me 6/19/2008 3PM.

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?

I know similar questions have been asked in the past, but I can't seem to get this to work for my specific case. I need to convert hours into minutes, and these times do not conform to a 24 hour clock. For example, I need to convert 1000:15 into 1000.25

I have a database which shows a time some one came into work and a time they left. Formatted as HH:MM. I can minus the time they left from the time they came in...to work out how many hours they worked. However, whenever i want to work out how many mintes it is (time left - time in * 60). It does not seem to work.

Example

A1 - Time In 09:00

A2 - Time Out 17:00

A3 - Hours = 8 (A2-A1)

A4 - Mintes should be 480. (A3*60)

Unsurprisingly I have a spreadsheet:

Column D contains the total hours that a component has been installed for

Column C contains the additional hours the component acquired

I need the total of these 2 sets of time added together to give me the new hours that the component has acquired. All cells have been formatted [h]:mm:ss

I attach an extract of the spreadsheet. At the moment the values in column D are all calculated manually. When I add the values together Excel returns #Value!

The annoying thing is that in cells B2 and A3 I tested this and can do this with no problem...the value in B3 is the sum of B2 and A3.

I have a spreadsheet that keeps track of my flight time by the day and then totals it for the month however, I keep it in a decimal number (i.e. 89.23). I want the final total number to be in Hours and Minutes hhh:mm and can not for the life of me figure out the formula to make it come out in hours and minutes. I can either convert the one final decimal number over to hours and minutes or add the entire collumn of decimal numbers and have THAT total converted to hours and minutes. It's doesn't matter to me. I just can't figure out the formula.

i don't know why this one stumps me but it does. I have a production schedule which shows how many hours and minutes are remaining for a given production run, i.e. 6.4 or 3.2. i want to do two things with these values. 1) add the 6.4 to the current time, something like a1 + now(0) to get the time the production run should end.

and

2) i want to add the number of minutes from a calculation to the current time, ie. 10:14 AM + 122 minutes = actual time the production ends. Nothing i do seems to give a desired result - including formatting the cell to any variation of the time format - including custom.

I am using Excel 2003 and I have two columns of data, one column shows how much work for a particular worktype should be done in an hour and the second column shows what I’m expected to get in over the next month. I have added a third column to show how long it would take to complete the expected work.

What I would like that third column to show the data in hours and minutes rather than a percentage of 100, so on a linked TAB on the main sheet it will show clearly as a time so staff hours can be allocate to a worktype. Is this simple to do. I have attached an example workbook.
