# Days & Hours B/t Two Dates & Times

Oct 23, 2008
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 ...

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 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.

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.

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 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 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.

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.

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.

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 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.

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"?

Today I am having a very annoying problem that really has me stumped – I need to work out the lag between a Due Date and Delivered Date

But as people sometimes manage to deliver on the Due Date it needs to show a zero (as in they got it in on time) but using the formula below the result is a 1 and I want a zero

Can anyone help me please? I have tried putting assorted -1s in to the formula and it looks like it might work until I copy down and find that if a person delivered one day early the result shows -3 for example!

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 think I can write a UDF and that may be the easiest. Is there a straightforward way without a UDF?

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'm trying to do a simple calculation of the # of hours between 2 times, rounded up to the nearest hours. Somehow along the way I've ended up with this massive formula below, which is doing what it's supposed to do except for certain cases (like the one in the attached file...where it says the difference between 2am and 3am is 2 hours) =ROUNDUP(IF(B2="",0,IF(A2="",0,(IF(B2<A2,((((B2+1)-A2)*1440)/60),(((B2-A2)*1440)/60))))),0)

in speeding up the below code as it does not seem to matter whether I use For, If loop etc - it runs too slowly. Basically we have one sheet which is input in a different timezone that needs converting to GMT... since daylight saving I wrote some code to cover the +/- 1 hour difference (this seems to work quite well) yet when it comes to converting the actual cells it runs incredibly slowly. I appreciate any help but its only the code after "Sheets("data").Unprotect" that i think needs changing. The time stamp is in column 7 - I hope this makes enough sense - which then gets converted by either 4.5 or 5.5 hours dependent on british summer time.

Sub TimeConvert()

With Application

.Calculation = xlCalculationAutomatic

. ScreenUpdating = False

.DisplayAlerts = False

.EnableEvents = False

End With

Dim FirstDate As Date

Dim Position, DayIndex, lgrow, lstrow As Long, TargetMonth As Long, Stweekday, Enweekday, Tdate As Date, TargetYear As Long, cell As Range

Dim bst As Boolean

TargetYear = Year(Now)

TargetMonth = 3

Position = "L"

DayIndex = 1
