Work Days And Hours Between Two Dates & Times
Apr 7, 2008
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.
Variables:
- 'Date Received' (H11)
- 'Date Actioned.' (I11)
-'Response Time' (K11)
Constants:
Work Days = Monday to Friday
Work Hrs = 8:30 AM to 5:30 PM (no lunch break)
Public Holidays = (AC13:AC30)
Formats:
Date Received: dd/mm/yyyy hh:mm AM/PM
Date Actioned: dd/mm/yyyy hh:mm AM/PM
Response Time: d - hh:mm
If there is someone out there wiling to put me out of my missery with this one, you will have a friend for life.

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
=TEXT(B15,"[h]")&" Hour"&IF(OR(TEXT(B15,"[h]")+0=0,TEXT(B15,"[h]")+0>1),"s "," ")&MINUTE(B15)&" Minute"&IF(MINUTE(B15)1,"s ",""))

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 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 need the difference between two dates/times field in hours or minutes.
Eg:
A1 B1
1/4/05 10:00 2/4/05 14:30
The result should be 13.5 hours, considering only 8 hrs per day, only business days and 8 to 5 workday.

Im trying to calculate hours and minutes between two dates/times over more than 24hrs. I have:-
A1 is 18/10/08 13:14, B1 is 20/10/2008 12:20, C1 is 1:23:05
Using the formula C1 =INT(B1-A1)&TEXT(B1-A1,":hh:mm")
But what I really need is just Hours and Minutes so the above should read 47:05.

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.

My workday function doesnt seem to be working correctly, it is including weekends.
My Spreadsheet is like this
A1= 01/01/2008 ( Date)
A2= 30
A3= =WORKDAY(A1+A2,0)
I am expecting the result to be 11/02/2008, but i am getting 31/01/2008.

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:
72hrs+ - return 1
48hrs-72hrs - return 2
13.5hrs-48hrs - return 3
0-13.5hrs - return 4
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.

I need also to calculate difference between dates(dd-mm-aaaa hh:mm) in workhours ( hh:mm):
The work period is 9-18 with lunch interval 13-14 The startdate and end date could be out of the work hours and i can't include the extra hours. I can have several days (workdays) at the difference, but i should maintain the format hh:mm.
Ex1:
Startdate 05-03-2013 18:34 ( date to calculation should be 05-03-2013 18:00)
end date 06-03-2013 10:30
Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )
will be equal to:
Startdate 06-03-2013 8:34 ( date to calculation sould be 06-03-2013 9:00 )
end date 06-03-2013 10:30
Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )
Ex2:
Startdate 06-03-2013 12:01
End date 06-03-2013 14:28
Time Difference 01:29

I have 2 dates+ times.
1 the contract start date and time.
2 the contract end date and time.
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?
Example
Start 06-Mar-07 10:00
End 14-Mar-07 14:00
This is 2 part days and over a weekend.

I am trying to find a formula that will return the number of week days between two dates. My specific situation is that my job sets up work orders (WO) to be completed by our staff. We have 3 dates - the date the WO was created, the date the WO is due to be completed, and the date the WO was actually completed.
I would like to subtract the Complete date from the Due date. Generally, this should always equal zero because our staff should be completing WOs on the due date! But obviously that doesn't always happen. There are times that they complete them late, and times they complete them early (yay!).
The problem with NETWORKDAYS is that even when they are completed on time, the result is 1. This formula counts instead of subtracts. I adjusted the formula to =NETWORKDAYS(A3,A4)-1 which works fine for those WOs completed on time or completed late. But for those completed early, it adds (or subtracts, really) 2 days. So for a WO completed a day early, instead of it showing -1, it shows -3. I've attached an example of WOs and the NETWORKDAYS formula I've used so you can see.
Subtract Days.xls
I'm really looking for something that will subtract week days, not count them.

I am creating a problem report spreadsheet for work. In col C I have a date/time that the problem started, eg, 23-Jun-2006 15:20 and in col D I have a date/time for when the problem was resolved, eg, 26-Jun-2006 15:40. I need to calculate the amount of hours that we were not available for use (due to the problem). This is based on a list of available hours. Eg, on Mondays we are available 19.5 hrs, T-F 22.5 hrs, Sa 14.5 hrs, and Sun 0 hrs.
If I do a straight subtraction, it uses 24 hrs for each day - not taking into account our available hrs. If I do NETWORKDAYS it automatically doesn't consider Sat or Sun - and i need it to - and it does have a DayEnd and DayStart but it assumes they are constants. I found the day corresponding to the date and thought I could determine the series of days between it, e.g., if the start day was Friday & the end day Monday, the series in between is Sat & Sun. Then I could do a lookup on all 4 days in a table & add them all together. But I can't figure out how to do this!

I need to create a spreadsheet that will calculate the difference between two dates and show the result in days. The complicated part is that weekends (Sat and Sun) need to be ignored and any time after 4:30 pm needs to be treated as the next business day. I have been trying to look at similar questions in forum and use the WORKDAYS function with little success.
Example:
A1- 14/08/09 4:40 p.m.
B1- 17/08/09 9:10 a.m.
I need the answer (B1-A1) to show up as 0. But if the time in A1 was changed to 4:20 p.m. than the answer should be 1 day.

I wanted to determine the number of days between two dates. Specifically, if the initial date is in one month, and the second is in a different month and an output would result a number of days in each month until the final date. BUT I have a large amount of data to do this for in a list view, way to put a formula in excel and just drag down the entire list to get the required information. see below for an example.
The result I'm looking for is the separate the months and only show the relevant months between the two dates in one cell or the adjacent. Something similar to the table outlined below.

In a project i am compiling i need to work accurately with times to calculate the work progress of the people in the workshop thus....here goes....
I have in work book #1 (7) sheets mon to fri + complete week + a sheet where all job numbers are collected.
From monday to friday the workmen log their times as a start time and a end time.

A1 is 10 (10 hrs worked) , A2 is 10:30am (in time), A3 is 9:00pm (out time), A4 needs to be the total hours and minutes between A2 and A3 based on the hours listed in A-1. What i need is a formula that will calculate the hours and minutes between the 2 times based on hours entered in A1 but that will also compensate for a manadatory 30 minute lunch that needs to be deducted from the total hours if hrs listed in A1 are more than 6.
example: worked 10HRS, 10:30am to 9:00pm, Total hrs is 10hrs 30min, which should be just 10 since the lunch is a none work time and must be subtracted.
If a person worked more than 6hrs, they must take a lunch. if they worked less, than 6 then they don't have to. I need a calcuation to recognize the greater than, less than factor into the equasion also.

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 trying to auto generate a calendar based on two drop down menus - Month and Year.
Once the month and year is selected I want to import all work orders onto the calendar based first on the "Labor Name" found in the list of work tab, then assign each work order for that labor name to the respective date on the calendar for the month.

Here is my set up:
A2 to BF2 is a range of dates
A3 to BF3 are sales. Days without sales are 0.00
I want to pick a range of dates and find the number of days without sales between those dates. So, a formula that will look to a start date in A1 and an end date in B2, and then count the number of days that did not have sales between. Index/Match/Countif/Dateif I can't seem to make anything work.

I am looking for a funtion that will help me add the hours someone is scheduled to work. The problem I am having is the format. Here's the format: The days of the week are Mon - Sun (D3-J3). L3 is a total of the hours they are scheduled to work for the week. Cell D3 is 8-2. Cell E3 is 9-3, etc. for the rest of the week. What I am looking to see if possible is in L3 take the row, Take D3 at 6 hours, E3 at 6 hours, etc for the rest of the row, and add them together for the total hours in L3. I have attached a small example file of what I'm trying to do. The format I am looking to use for the hours is as described above.

I am working on a spreadsheet where I want to count the number of calls to our service desk between specific hours (ie. 6:00 a.m. - 7:00 a.m.) up through 8:00 p.m. I have looked at all the forums and tried all the formulas that seemed to be what I was looking for and it isn't working! I am adding the information to a summary spreadsheet from which I am gathering the information from other sheets in the workbook. This will be an ongoing spreadsheet done weekly for every month.
Examples: I need to know how many calls from these times on a summary sheet.

I have a questions about counting days and hours.
Imagine that i have an item entering my warehouse on 22/05/2008 at 21h35 and leaving on the 25/05/2008 at 5h42.
A1= 22/05/2008 and B1= 21h35
A2= 25/05/2008 and B2= 5h42
The goal is to count the full 24 hours day and the remaining hours.
For the example given i can say that on day 22 the item only says 2 hours and 25 minutes, on day 23 it stays 24 hours and on day 24 another 24 hours, on day 25 the item leaves at 5h42, so it only stays those 5h42.
So we have 2 full 24 hour days and 2h25 plus the 5h42, the the item were stored 2 days and 8 hours and 7 minutes.
The problem is when the item arrives at (example) 22/05/2008 2h00 and leaves at 25/05/2008 23h00 on another day. Lets say that on the first day the item is 22 hours stored, plus the 2 full 24 hour day and another 23 hours.
So it is 2 days plus the 45 hours, that is 2 days plus 1 day and the remaining 21 hours.
how to add to this 2 full days the 1 day and 21 hours

I am trying to figure out the calculation of cycle time from my worksheet. I have 1419 hrs equals 59 days 03 hrs.
If A2=1419
I tried this formula
=INT(A2/24)&" days " &MOD(A2,24)&" hrs"
Which gave me an answer of 59 days 3 hrs.
I was wondering how they got "03 hrs"?
