Difference Between Dates & Times In Business Days With Time Constraints

Aug 16, 2009

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.

Difference Between Dates And Times In Days , Hours Mins ( Working Hours )

Mar 2, 2010

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 ",""))

Finding The Difference Between Two Dates And Times?

Feb 14, 2014

I am having difficulty finding the difference between two times and dates in Excel. I have researched this on Google and tried several formulas but none have worked for me. The format the data is currently in can be seen below:

A1: 1/3/2014 11:00:02.230 B1: 2/7/2014 08:42:37.637
A2: 2/12/2014 07:51:58.663 B2: 2/13/2014 05:36:31.893

(Note all times are military time format)

I want to display the difference in C1 in a format along the lines of "dd hh:mm". The data for seconds and fractions of a second is included in the source data but is not needed in the final results.

If the date and time falls on the same day, I have no trouble doing a simple "B3-A3" to determine the answer. For example:

A3: 2/5/2014 09:56:06.273 B3: 2/5/2014 10:39:51.34

Gives me an answer of: 0:43

Trying to do the same for A1 and B1 gives me this: "03 21:42" when I format it to "dd hh:mm".

Is there a formula that would give me the correct answer in both of these cases?

Difference Between Two Dates/times In Hours

I need the difference between two dates/times field in hours or minutes.

Eg:

Calculate Workday Difference Between Dates/Times

Jun 19, 2008

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.

Calculate Day Difference Between Dates Excluding Certain Days

Feb 2, 2008

I am attempting to get the formula in Column "E" (see attached excel file) to work based off the individual reps 'days off / holidays' (Columns K:P (or more as needed) that they might have. the formula I am using (which works fine) is:

=IF(C2=D2,0, SUMPRODUCT((WEEKDAY(ROW(INDIRECT(C2&":"&D2)),2)={2,3,4,5,6,7})*(COUNTIF($K$2:$S$2,ROW(INDIRECT(C2&":"&D2)))=0)))

My issue comes up when I am coping this formula for say 100+ rows. When I copy the formula to all of the rows, the (COUNTIF($K$2:$S$2) becomes static and does not realize that the row (ie. Row 26 Rep C) has different days off than Rep A. I can manually change the reference for the countif to specify the correct row to their own days but that becomes tedious very quickly. I was wondering if anyone has come across a way to make the countif work based off of that the name in Column B matches the name in Column G then looks 'to the right' and uses the 'days off' that are listed for the corresponding Rep. I have tried a few different ideas but nothing has worked so far.

Calculating Difference In Months Between Dates / Ignoring Days And Years?

Mar 13, 2012

Cell A1 contains 02/29/2012

Cell B1 contains 12/01/2006

I am looking for a formula that will return the number of months (periods) between two dates, ignoring days and years. Using the above dates, which cannot be changed, the result needs to be 63. The formulas I have tried keep returning 64 because my later date is at the end of a period, and my earlier date is at the beginning.

Difference Between 2 Dates, Incl Weekends, With Variable Work Days

Jul 11, 2006

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!

Subtracting Time (finding The Difference Between Times)

Dec 8, 2009

I am having trouble finding the difference between times. I have two cells, A1, A2. Times will be placed in there each day. A1 will have the first time and A2 will have a later time that day. i.e. A1 12:25AM, A2 2:45AM. A3 would have the formula. In this case I am looking for an answer of 2:00 (2hrs).

My second issue will be times when I have A1 11:20pm and A2 1:20am. I can't seem to get it to work.

Converting Time: Subtract Two Times To Get The Difference

Dec 14, 2008

I'm trying to subtract two times to get the difference. Entries are in military format (1615) and VBA converts the time to 16:15. My problem is that when a time is entered between 0001 and 0059 (i.e. 0015), the VBA converts the time to :15. My formula does not recognize this, but does recognize 0:15 (entered without VBA). The cell is custom formatted as h:mm. I've tried several other formats including [h]:mm but can't get any to work. How can I get a formula to recognize it?

=IF(U12<T12,(U12+1)-T12,U12-T12)

where U12 is :15 and T12 is 23:00

Time Difference Formula Where Both Times In 1 Cell

Aug 14, 2007

I need some IF formula I believe that will yield an answer between 1 - 5. I'm not swavey enough with these things to figure this one out... trust me I tried and it keeps getting more confusing for me.

If the time worked is between certain time criteria then it would equal 1 - 5 depending on the time.

Example: If I work between the hours of 5am and 1pm then I would be in the Open/Mid range and would need to equal 2. If I only worked a few hours and my hours fell only between the Mid range then it would equal 3.

Then based on that... It would automatically fill in on the deployment charts... My name would show up on the Open and Mid Deployments under the task chosen for me to do that day.

I've attached a small sample of what I am looking for to kind of help show what I need. The highlighted areas are the areas I'm not sure how to do.

I cant 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.

Calculating Time Difference Between Two Days Combined With IF Formula?

Jan 30, 2014

I am using the following formula in Column E to calculate the difference between an employees start time, and their previous shift end time in order to work out how many hours rest they have had:

=IF(A4=0,"",IF(I4=0,"",MOD(I4-B4,1)))

My Current Formula works fine for same day calculations, but if an employee finishes work at 18:00 on Friday and starts work at 22:00 Saturday night, Excel calculates the Total Rest hours as 04:00, when in fact they have had 28:00 hours rest...

Is there a way of calculating the hours difference between two dates?

I have attached a sample of my spreadsheet to illustrate

Time Difference Between 2 Dates

Jan 13, 2013

I work at a call center and I get the data as Date, Time of calling and Duration of the call. Now since this is an overseas call center, even though the calls spills over 12midnight, the corresponding date shows as the date when the agent logged in.

So I get the data in this format, Date: 06/11/2012, Time: 19:00:00 - 04:00:00.

How do I calculate the time difference at one go without first getting the time difference from the time of login till midnight and then add that to the time difference of midnight till time of logout. I have attached a file for your review.
