Add And Subtract Dates And Times
Oct 25, 2011
I have a table that I am storing into an array. I have an array FDate where I store a date and another array FTime where I store times.
FDate is formatted as m/dd/yyyy Hh:Mm: Ss
Ftime is formatted as Hh:Mm:Ss
I know in excel that you can add and subtract dates and times. How do you accomplish the same task in VBA?

How do you subtract start/end - dates/times in vba?
I know how to do it with formulas, but can't grasp it with vba. My range will always change, so I'm trying to avoid formulas (Cutting rows etc...)
I need Col D-Col B (end date-start date) and Col E - Col C (end time - start time)
Would doing the calculation on the userform be the best way, or trying to do the calculation with the ws code?

In the same period of time I have two countings of different stopped time.
sheetA
range (A3:A23), = product code.
range (H3:H23), = time used.
with this formula I take the time used for each product. "= SUMIF($A$3:$A$23,M2,$H$3:$H$23)"
sheetB
On this one I record all different lost times in the same period of time.
What I want is:
Take out from the result obtained with the above formula, the time down from SheetB.
Ex:if I used on sheetA between 7:00 and 18:00, 4:10 of the product A, I want to take to this value the downtime in the same period from sheetB.

I am trying to subtract from a collumn 14 seconds from the time that is in the cell. I do not want to manually enter in a formula, or copy and forula into the cell as there is a large amount of data for this. The report will be updated daily and will need to always subtract 14 seconds from the time, and the result should be populated in the cells that the time is subtracting from.

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

I get a spreadsheet downloaded to excel with a variable of 15 names.
I want to create a formula that if the name Cleardale appears to take the time responding in cell BD and subtract it from the time available in cell AV so that I have the time on task and then to add up all those times in a total time on task for all cleardale listings for that day. The times are listed in the 24 hour format. I keep getting errors. Can anyone help me out on this one? The range of the cells is from AV7 to AV500 for available time and BD7 to BD500 for alert time and the range of the names is cell f7 to f500.

I have created a userdefined function. the Idea is for the user to calculate the difference in hours and minutes. The input would be like budtime = 30 , realtime = 1.25 the answer I would like to have is 28:45 (28hours and 45 mins). Im aware that I can format the cell manually with [h]:mm but I'd like the function to do it.
I have written this:
Function RT(BudTime, RealTime)
RT = Format(((CDec(BudTime) - CDec(RealTime) / 24)), "[h]:mm")
End Function

Seems that when I subtract a future date from NOW() and format the cell d:hh:mm that the result is 1 day off. So if I subtract NOW() (today is 10/24) from 10/25/08 it returns a 1 for the d when I would expect it to be zero.

I have 2 cells in a row that are times, it has been a while since I did any work in excel. I want to take the first cell as start Time, the second cell is end time and I need to subtract them and put the total in a cell called Hours. What is the correct format to use and how would I do the subtraction.
Generally start time will be AM and End Time will be PM.

I have a column with start date and another next to it with end date. I now want a third column that gives the number of days alloted. I tried
=G6-F6 and that didn't work. What should I do?

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.

If you have some low time resolution data you need to compare with high time resolution data how do you average the high resolution data. For example data that starts and ends a fortnight apart and you want to compare it with data that starts and ends 1 hour apart you need to average the hourly data to do so. I can't figure out how:
So if I had Sheet 1 with hourly data
A B C D E
1 Date, Time, Measurement
2 01/01/2014, 01:00, 62
3 01/01/2014, 02:00, 38
etc....
Then in Sheet 2, fortnightly data
A B C D E
1 Date on, Time On, Date Off, Time Off, Measurement
2 02/01/14, 15:23, 18/01/2014, 12:25, 52
3 18/01/2014, 12:25, 01/02/2014, 14:19, 34
etc....
I'd want to add a new column of data to average the hourly data so I can use the correl function.

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.

I am trying to create a "daily donut" to track how long it has been since I left for my current deployment, and how much time I have left until I return home. I would like to show exactly how many year(s), month(s), day(s), hour(s), minute(s), and second(s) (like 1 year, 4 months, 4 hours, 5 minutes, & 34 seconds not 1.0 year, 0.33 months, etc.) it has been (again, not 3600 seconds, 60 minutes, 1 hour, etc.), and how many I have left. I have spent many hours trying to figure this out, and I have even tried looking through this forum, but I still can't completely figure this out. I was close in figuring out the date differences in the x amount of years, months, and days format, but it wouldn't account for the time. I.E., 06/03/09 05:00:00 AM - 06/01/08 06:00:00 AM, would show 2 days, instead of 1 day (I'm not sure how to incorporate the time yet).
The variables are:
A1 Date I Left For My Deployment in M/DD/YY HH:MM:SS AM/PM
A2 =Now() Function in Same Date & Time Format as A1
A3 = Date I Get Home from My Deployment in Same Date & Time Format as A1
Any ideas or help? And if possible, I would like to be able to do this using excel's built in functions (not excel add-ons, vb, etc.), so that it would work on government computers.

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 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?

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.

I'm not too hot with Excel formulas but I'll explain as best I can. I have 3 columns with dates and times
A - 01/08/2008 08:17:08
B - 01/08/2008 12:17:08
C - 01/08/2008 17:00:11
This is what I want to do...
If A > B then Calculate the time difference between A and C
If A <= B then Calculate time difference from B to C
I'd like to get this formula in 1 cell if possible?

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 have dates (column E) and times (column F) currently in the format mm/dd/yyyy and hh:mm .
However, my formula in excel deals with dates and times in the format mmddyyyy and hhmm. How do I change the values of the dates to exclude the "/" and the times to exclude the ":" operators?
I want to change the actual value of the cell too. Basically, using custom format mmddyyyy in the date column will not work (because the true value of the date will still yield mm/dd/yyyy.
