I need to calculate billable hours.I have a start date/time and end date/time.Then I need to subtract out all time between 05:00:00.000 and 20:00:00.000. These are not billable hours.But I can include all weekend time.And I can include all holiday time.I need to accomplish this with formulas, no macros.

I need to calculate the hrs between two date and time and deduct any time outwith the hrs of operation (09:00-19:00), if the date and time falls outwith these times. I have used the formula 24*IF(A2>G2,G2+1-A2,G2-A2), where G2 IS 21/04/2008 11:45 and A2 is 20/04/2008 00:22, but can't get it right.

i need to get a formula that will calucate hours and min. its for how many hours the employee has not worked. some of them would be strait hours some would be just min there is no way to tell.

example lates 2 hours anp(absent no pay) 12 hours sicks 55.5 hours no calls early outs 21 min (this is just an example if it were real this person would be fired)

i know this adds up to 69.85 hours but i can't fuiger out a way to get it to calucate in excel. i know i could have it all changed to min and then devied by 60 to get the hours but how do i get it to read what is mins and whats hours?

I need to calculate the difference between a start time and end time in hours and minutes.

Start 01/07/2008 11:40

End 01/08/2008 19:28

Start and End columns are formatted as 'Custom' m/d/yyyy h:mm.

I'm not sure what formula to write to calculate the hours and minutes between the two times. Everything I've tried doesn't count over 24 hours. Also what do I format the result cell as?

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 want to Sum up the minutes in the particular Column, so that at the end with i put formala, the output would be X Hrs X Mins, one more thing i would like to do in it is , I want to copy paste the value of formula in next column, for eg the formula is in A6, i want value of that formula in B6.

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.

This is for employee time sheet and schedule. I have multiple employees work a specific shift on various days. I need the calculate the hours worked each day and then have them totaled at the end of the period. Here is and example:

Employee Monday Tuesday Wednesday Thursday Friday Saturday Sunday Total Hours Total Cost John Smith 10-5 12-6 9-2 5-10:30 3-8:30

How do I get it to calculate the difference in the same cell, convert it to hours, add up all the results and place it in the totals columns then calculate those totals by their pay rate to get my Labor cost?

I have problem to calculate the time which is more than 23:00:00hrs in a file. I need to compare the benchmark time and the difference of time(start time and end time) and show pass/fail depending on benchmark set time. For few of the times which is more than 23:00:00 hrs the format is taking different(example: for 49:15:48, it is showing 02/01/1900 01:15:48 in formaula bar) for which i am not able to use formula and know pass/fail.

I receive data from a company I deal with that has the date and time of all of my transactions with them listed in an excel worksheet. Only problem is that the date/time that I receive is not in my timezone, which is a bit of a problem for me!

What I want to do is to be able to adjust the date and time shown in the cell forward by 14 hours, so that the data is shown in the timezone that I am currently in. So the end result for the first line of data in the attached file would end up being 2006-08-11,10:28:51 instead of 2006-08-10,20:28:51.

I got a problem with a time calculation, if it's even possible.

I want to calculate the amount of hours that have been woork in a slot.

Example: First slot is from 08:00am till 17:00pm, time cost 100% Second slot is from 1700am till 24:00, time cost 110% Third slot is from 24:00 till 08:00 am, time cost 120%

I'm working from 08:00am till next day 01:00am So my hours are: 9 in slot 1, 7 in slot 2, 1 in slot 3.

I can’t figure out why this formula is not working. I am trying to alter it a little, but I still think it should work. Here is what I am trying to do. I am looking to calculate the time difference between two work projects, but exclude time when the office is closed. So someone starts a project at 2pm and finish 10am the next day it will show a result of 4 hours because the office closes at 5.

Here is the formula. It is the time formula from cpearson.com ...

I have call data in date/time 06/07/08 2:00 PM custom format for a 2 month period. I have my regular opening times eg Monday 9-3, Tuesday 10-4. For each call I want to know if it was made during opening times or not.

It's been several years sine I had to look at calculating amount of time worked. Can you please look at this old spreadsheet of mine and verify that the formula is correct?

It appears to be ok to me, but I don't want any errors when it comes to paying my employees

I am creating a 'HelpDesk Issue Logger' and I am trying to calculate the Network Days and Network Hours between two dates with times. I want to know how many business days and hours are between the two days to give me a TURE 'Response Time.'

I have been to several sites and forums looking for the answer, but I have not been able to find a solutions that works for me. Please find attached a 'stripped' down version of my project.

I need a formula to calculate hours worked between specific times. In the worksheet I have, I need to calculate the hours worked between 5am and 10pm, the start time is in C7, and the finish time in D7 the formula need to be in H7, and another formula in I7 to calculate hours worked before 5am and after 10pm .

I have made a userform where I calculate how long time an operation takes. If the time fe.g. is 25 hours and 24 minutes then I get the result 1:24. I have attached my userform as it looks now. If you write 540 in the bar and 550 in volume and press "Beregn" then "Norm tid + 10%" will write 1:24 and not 25:24. Is it possible to have the Userform to write 25:24 or 1day and 1 hour and 24minutes?

I have a spreadsheet used for calculating information based on the dates specific shifts are requested/cancelled by our clients. I have a formula for working out if a date & time of cancellation is less than 48hrs notice of the shift starting. This is because we have cancellation fees based on this.

What I have is this formula: =IF(A16="","",IF(INT(A16)-INT(G16)<2,1,"")) that returns a 1 if that shift is cancelled within 48hrs notice. This works fine but I have to now change the notice periods to the following:

edit this formula to take this into account? I figure it's using multiple IF's and changing the <2 into something else like the number of hours but I'm not sure of the exact syntax.

Can I calculate the number of working hours between these two using a formula? So if I have a 10 hour working day (08:00-18:00), Mon-Fri and the two Dates/Times can I calculate the number of working hours?

I would like to calculate the total hours between two dates using a unique formula and without inserting new columns. I have attached an example of the data I'm working with.

How to calculate the hours between two dynamic dates.

Rules 1: It has to calculate only office hours (Let's say 9 AM to 5 PM)

Rules 2: The starting time may fall before 9 AM, then we have to do calculation from 9 AM on the same day. (Let's say start date with time 17/04/07 7:00:00 AM, then we have to consider the date with time from 17/04/07 9:00:00 AM for the calculation)

Rules 3:The starting time may fall After 5 PM, then we have to do calculation from 9 AM on the next day. (Let's say start date with time 17/04/07 8:00:00 PM, then we have to consider the date with time from 18/04/07 9:00:00 AM for the calculation)

Rules 4: It has to exclude the Saturday and Sunday

I seem to have the worst luck when it comes to getting dates and times to calculate together. My logic just seems to go straight out the window.

What I am trying to do, the end result, is get a Time Worked (duration) that I have spent on a ticket, and a Total Time, the time a ticket was opened, to the time it was closed.

I guess we can try to do this one step at a time.

The first thing that I would like to know is if there is a way to calculate Date/Time in a MM/DD/YYYY, H:MM format?

IE: Ticket Opened ...................Ticket Closed 5/16/2008 2:54 PM..............5/19/2008 10:47 AM Total Time in Days / Hours / Minutes

Right now I have the Date and Time split into separate cells, simply because I couldnt figure out a way to subtract the combined date and time.

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.
