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 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 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 .

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'm looking for a formula that will calculate the difference in times between specific times while working with a 24 hr clock. Please see details below:

E3 provides the start time of 4:00 H3 provides an end time of 15:30

If an employee works betwen the hours of 0:00 (midnight) to 5:59, this is considered DIFF hours and is therefore the number I am seaking. So for the data noted above, the total DIFF hours worked is 2 hours.

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 ...

Basicly we pay single rate between 8.00am and 8.00pm at all other times and on bank holidays and weekdays we pay an enhanced rate. If I can calculate the standard hours then the remainder of the hours are enhanced. Aim to count how many work hours fall between a standard start time (SHS) and a standard end time (SHE) (currently 8.00am and 8.00pm), that do not fall on a weekend and are not a bank holiday.

Column B = Start time (eg 06:00) Column C - End time (eg 22:00)

Column D= date (from which day of week is derived) Column E = Y or N for whether it is a bank holiday or not..............

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 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.

From the below example, I would need to know the difference between date & time of Received and Resolved in number of days. Meaning - time difference should also be calculated in days

CELL ACELL BCELL CCELL DCELL E - REQUIRED OUTPUTReceived DateReceived TimeResolved DateResolved TimeTurn Around Time - IN DAYS20-Jan-122:43:00 PM23-Jan-124:50:00 PMDifference between Resolved date & time and Received date & time

i have a timesheet that we are trying to use. the problem is the column that says shift diff. if an employee works after 6:30pm for 1and 1/2hr, he is entitled to shift hours. shift hours is between 6m and 8am.

As long as he works after 6.30pm but works for at least one and a half hour, he will get the shift.

if work, 9am to 7:30pm, and have break between 2-3pm, should have 1.5hrs shift and 9.5hrs total if work, 7:45pm-9:45pm, and have break between 8:30-9pm, total hrs work is 1.5 and shift hrs s/b 1.5hrs if work 3pm to 12am and have break between 7-8pm, total hrs work is 8 and shift hrs s/b 5hrs

How should I calculate working hours between two dates? Say if start at 9/25/2009 7:26:13 PM and finish at 10/20/2009 9:46:13 AM, the function should return 245:20:00 because the working hours are from 8am to 11 PM (8 - 23), and there are weekends between the dates. Preferably the function should work like the NETWORKDAYS() function, but it should also include the time, not just the dates.

I have a spreadsheet with Received Date/Time in C2 and Resolved Date/Tim in D2, Work Start Time in E2, Work End Time in F2. C2 and D2 are in dd/mm/yyyy hh:mm AM/PM format:04/03/2008 10:27 AM06/03/2008 1:06 PM9:00:00 AM5:00:00 PM

I need to be able to calculate the resolution time of each request in hours/mins excluding weekends and public holidays. I've tried using the NETWORKDAYS function but it doesn't seem to pick up multiple days between the Received and Resolved dates/times. I have put the Public Holidays in my spreadsheet ( attached) in AA2-AG2.
