Assuming that a workday is from 8:30am to 5:00pm. (also need to not calcualte Saturday and Sunday but this example doesn't show it).

Wednesday, 7/18/07 at 4:00pm (minus) Friday, 7/20/07 at 9:00am (should equal) 10 hours or 1 day, 1 hour and 30 minutes.

Basically what I want to do it determine how much work time has elapsed from the time a message was left on voicemail to the time that someone picks that message up. We only want to assume that a message can be retrieved duruing business hours but a message can be left at anytime!

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 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.

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?

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 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.

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.

I have a user form with textBox1 = start time (entered as "[h]:mm") and text Box2 = finish time (entered as "[h]:mm"). I would like textBox3 to display the difference between the start time and finish time as a general number!

For example Start time: 21:00 Finish time: 06:30 Hours worked: 9.50

Is there a way to have it show the number of days, hours, minutes and seconds? So it will say 45:1:23:42? (45 days, 1 hour, etc...) Or something along these lines?

Just basic enter a start time in column A a finish time in column B and column C gives you total in hours and minutes and then maybe a way to sum those hours and minutes. how to do "Math" on time and how it should be entered (formatted) for it to work properly.

I've got a worksheet that deals with dates and time. Similar to a checkbook, I need to take the balance and subtract what's taken from that. But the writer copied this from another software program and it's in this format. How do I convert it to a time format? Or is that what I really need? Right now the taken and balance are both in a general format.

I just need to know on any of the given days what the balance of this person's time was in hours and minutes.

i need a vba code , i have time in column F like 8:30 , 3:30 , 5:30 , 8:30 , 9:30.......i need a macro which will add 00:30 in all cells in column F if time is less than 7.00 hrs

basically I am trying to make a time calculator for work, I want it to automatically add the hours up but then also minus break times and then give me a whole paid total hours worked that week.

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?

I am a truck driver and keep a record of my loading times when I am loading and unloading. At the end of a trip i transfer all the data to my computer, then "auto sum" the "HOURS" and the "MINUTES" columns. At the bottom of ech trip I end up with figures, lets say 32 (hours) in column "J" and 303 (minutes) in column "K".

Now 303 minutes is {5 hours and 3 minutes}. Now we all know that mathematically we can work out that {3} minutes is 0.05 of 1 hour and that would make the total time worked 32 (hours) + 5 (hours(from the minutes)) + the last 3 minutes and the total is 37 hours and 3 minutes.

What I am in need of is a formula that will take the hours in column "J" add the hours from column "K", leaving the minutes to be converted to 0.05, giving me a total in cell "M29" that can then be multiplied by the wage rate in cell "M30", giving me an amount that I should be paid in cell "M31"

if someone called me at 4:55pm and ended the call at 5:10pm, the whole call lasted 15 minutes. So, I want to show on excel that the call lasted 5 minutes in the 16th hour of the day (4:55pm) and 10 minutes in the 17th hour of the day (5:10pm), for a total of 15 minutes.

I have the following time ranges that need to be converted into total minutes. Examples (from easiest to most difficult)...

The items below are in column A (each range is the content of just one cell):

00:00-13:00 06:30-13:15 13:30-13:15 (this spans two days, so it's actually 23H and 45M) 23:30-03:00 & 16:00-22:10 (only the first time range matters; the second can be omitted)

So for 00:00-13:00, we have 13H and 0M = 13 * 60 = 780. And for 23:30-03:00, we have 3H and 30M = 3.5 * 60 = 210. But how do I automate this process with the text entries above (and hundreds more that are imported in this format).

Need to display time in total minutes but with a space after every 3 digits.

For instance, I can display 0.833333 as total minutes by using the custom number format [m] which displays 1200. But I need it to display as 1 200. I know with a standard number, I could use # ##0 but I don't know how to get both of these custom attributes to work simultaneously.

I trying to figure a formula to convert time on a phone call eg. 01:01:21 into total seconds (3661). Phonecalls will never be more than an hour long but the spreadsheet I will be supplied with (havn't got it yet!) will display them in the 00:00:00 format.
