Duration Formula
Feb 16, 2010
I have the below Date & time in cell a1 and another date and time in cell a3
8/2/2010 08:45:00
8/2/2010 10:15:00
I need to be able to show duration (in hours) between the 2 times, in this instance its the same date, but this wont always be the case. To add a level of complexity in addition to the gross duration in hours, I will also need to know how long (in hours or mins) of the duration fits into "in hours" ( 9 -5 mon- fri) then the duration thats fits "out of hours" (after 5pm weekdays or all day Sat & Sun)

What is the formula for calculating duration in min/hrs between start time and end time without mentioning any date, and if the end time stretches to next day i.e beyond 12.00 midnight. And what is the logic used in the formula.

I need a formula that will calculate the percentage of the total duration between two dates (in dd.mm.yyyy hh:mm format) that a third, intervening date represents.
As an example:
a) 10th Jan 2014 09:00
b) 20th Jan 2014 09:00
c) 30th Jan 2014 09:00
In this case the answer sould be 50% because 'b' represents exactly half of the time elapsed between 'a' and 'c'.
Note: the formula needs to work effectively across the boundary between two consecutive years.

I need a formula that will calucalte the monthly total based on the following conditions:
Col A = Yearly Cost
Col B = The number of the month when the costs are starting (1=Jan etc)
Col C = The duration or the number of months for which the costs are to spread
Col D is Year 2013 with the months across columns D-O. Row 1 above those columns shows the month's corresponding number.
Right now I have =IF($B3<=D$1,$A3/$C3,0) however if my start month is 1 and my duration is 5, I need the costs to stop after May. I've attached a sample file. Calculate based on start month and duration.xlsx

I am trying trying to calculate the amount of time students view videos. I understand I should use [h]:mm:ss but excel continues to convert entries such as 0:14:59 (0 hours, 14 minutes, 59 seconds) to 12:14:49 PM both in the cell and the function bar.
The problem gets complicated because I have entered the data with two different formats; some in h:mm and some in h:mm:ss'
1) Is there an easy way to sum the duration time so it accurately reflects total hours:minutes:seconds?
2) Do I need to reformat or re-enter data to make it work?
3) If so, is there a macro to do it?
This has been a bear, (40 students by 30 videos) all hand coded.

I have a worksheet where I calculate the duration it takes for an operation. the format of the worksheet is as folows:
The worksheet is composed of Start and Finish times in this format: 2009/06/02 5:32:19 , so for example,
- Row1 of the worksheet will have "Start" in column H1 and the start time in column B1
- Row 2 of the worksheet directly below has the "Finish" time, with the Finish time information in column B2
So with the help of excelforums I was able to implement a macro to extract the finish time cell found in row B2 and offset it to C1 and do a simple calculation to get the duration in minutes and display it in column D of the same row as "Start".

I'd like to write a VBA script which writes all data of my mp3s in a spreadsheet. I can read all data like the artist, songname, album, year, this works fine. However I'm not able to get the duration of the mp3 files. Any sample script which reads the duration of the mp3 files?

I've recently been experiencing some strange phenomena in relation to public variables. It seems that if I run separate routines in quick enough succession (e.g. press a button twice within a couple of seconds), the memory of the public variable "hangs over" into the second routine.
The routines, however, are completely separate events. And I'm not using userforms or anything like that in order to keep VBA running in the background. In which case it seems that Public variables don't always get set to nothing with the end of the final sub in a routine. Has anyone else experienced anything like this? I was under the impression only Static variables could do this.

Is there a format for duration of time. The attached spread sheet has column B "Duration". This is the actual time on which I need to do calculation. On "C2" I have the formula "=IF(B2>10,400,B2*40)". The formula is " if value in B2 is more than 10 hours then the value in C2 should be $400 , else C2= B2(duration time) multiplied by 40.

I have a Log In/Log Out report that I need pulling data from.
Ultimately what I want to do is get the amount of time my employees were logged out.
I am using Excel 2003. Attached is an example of the data I'm working with.
Sheet 1 contains the data, and Sheet 2 will be the summary.
So, looking at Bob's times: If column A contains Bob (A2 in this case), and the same row in column G (G2) contains 79, subtract the contents of the same row in column F (F2) from the next row down in column D (D3) (which would be D3 - F2). That result should populate on Sheet 2 next to Bob's name in h:mm:ss format.
If there is nothing in the next row down in column D, then do nothing.
I would like to leave the data as is, if possible. There are extension numbers next to the names in the data. If possible to ignore those when rolling up to the summary that would be useful. Also, on the summary sheet, if the employee is not on the data sheet (if they had the day off) they can have 0 or NA or something to indicate there is no data for them.

I have a table of projects with 1) duration in year, 2) time window (number of years of our planning cycle), and 3) start year of the project. I want to generate a list of project parts of all projects where they may take place. This will serve as an input to an optimization program.
So a project of 2-year duration should have 2 parts over any year within the time window. I am including the "impossible" ones for my developer to tag them as "0" when we run it through his code.

I was wondering if there is a formla that will delete a formula when it has done its calculation, or stop the formula from constantly updating.
I've got a formula
=IF(COUNTA(A1)=1,TODAY(),"")
When something is typed in Cell A1 the cell with the formula will input todays date.
Is there a formula that will stop this formula from updating, as when you go into the file on a different day the date would have been updated.

I have a situation where I have to curve fit data, this can lead to different formulas being used with varying constants.
Is it possible to pickup a TEXT based formula and related constants from other cells, and then place this into another cell as a functioning formula. For Example
Cell A1 contains the formula as a text string whether it be y=a+bx+cx^2, or y=a+b/x, etc
Cells A2:A6 contain the individual constants, a, b, c, etc
I would then want the VBA to read the text based formula and put it into an output cell as a functioning excel formulae.g
In cell B10: =a+b*A10+c*A10^2
I understand picking the constants up and putting the formula should not be too much of an issue, however trying to insert the variable form of the curve fit is the part that I am struggling with, and am unsure if possible.

Here is the scenario:
A B C D
BananasApplesOrangesTotal113=A1+B1+C1
I need to reference the formula in D1 with the cells headers names.
In a perfect world, it would take
=A1+B1+C1:
and produce:
=Bananas+Apples+Oranges

I am trying to use a combination of Concatenate and IF formula to produce an email.
My input.
D4: First Name:
D5: Middle Name:
D6: Last Name:
D8: Organization:
Once all these are filled, I want the formula to produce a result like
FirstName.M.LastName@Organization.com
I have used the following formula.
[Code] .....
Problem is if there is a middle name the formula works fine, but in case where there is no middle name, it produces the following result.
FirstName..LastName@Organization.com
How do I remove the additional (.) in cases where there is no middle name.

I'm having some trouble trying to get excel to input a formula into a cell. I'm still a novice at VBA right now, so I don't think my problem will be too much of a brain buster.

Is it possible to write a formula that skips x number of cells and have the formula autoincrement as usual. For an examples lets say I want to skip 3 cells and I have entered in the cells listed:
A1= "1"
A2= "2"
A3= "3"
Then I type in the simple formula in the cell
B1= "=A1"
and then drag down but it skips 3 cells so then
B5= "=A2"
B9= "=A3"
If it didn't skip then
B1= "=A1"
B2= "=A2"
B3= "=A3"
this is just an example as I will be writing more complex formulas and need some thing that I can write into the formula so that it skips.
Something similar to this B1 "=A1(skip3cells)"
