Subtract 4 Hour From All Cells In A Column

Mar 15, 2014

I have a column of times that are formatted 12:30:00, 14:02:00.....so on and so on. I want to convert these times to be 4 hours less than what they are. Is there a formula I can put in a cell somewhere that will do this for me?

Changing Date/time To Run A 12 Hour Production Schedule, And Not 24 Hour

Sep 4, 2006

I have created a daily schedule which has a number of factory variables taken into consideration which determine the date and time a particular product should, barring any mechanical problems, come off the machine. (see attached spreadsheet).

The date at the top will be editable by me only so that when I update the production quantities, the “date/time off” column automatically re-adjusts to the remaining quantities.

The formulas are a little long winded, but I have left them that way whilst I try and develop it. I should be able to figure out how to condense them later.

My problem is that the “date/time off” on the right works excellent, but over a 24 hr period.

Ordinarily, we work a 12 hour day (6am to 6pm) with overlapping shifts to cover breaks, and 20 mins warm up at the start of the day for the machine, thus maximising a 12 hour day.

Of course if demand exceeds the allotted time we put on overtime.

Is it possible to specify that normal days are only 12 hours so that if a product exceeds 6pm, it flows into the next day with the balance starting at 6:20am?

And, if the production for the week exceeds the time could I stipulate particular days which we deem are suitable for overtime? Ie, we decide Wednesday is a 14 hour day and not 12.

I had toyed with the idea of creating a 365 day table/calendar, on another worksheet which would have its individual allocated hours in an adjacent column and somehow link them to the date/time off, perhaps by way of a VLOOKUP, but I have been chasing my tail trying to figure out how to implement it.

Excel 2010 :: Counting Users Per Hour For Each Hour

Oct 21, 2013

I work in a computer lab and we have to keep track of how many people sign in (using excel 2010), and how long they were here.

I'm looking for a way to count how many entries were made per hour for every hour someone was signed in.

For example someone signs in at 9:22 am and leaves at 3:34 pm.They were here from 9-10, 10-11, 11-12 etc.. and its getting very tiresome to go through and manually enter a "1" for each individual hour in each cell under the hour.

Is there a way I can feed the in and out times into a spreadsheet and have it automatically count how many people were in the lab each hour?

Excel 2013 :: Formula To Subtract 7th Column Values From Column Before 1st Loop?

Feb 21, 2014

I have a code that inserts a new column after every 7th column. I want to include a formula where every 7th column value is subtracted from the values present in the column before the 1st, or you can think of it as subtracting 7th column of the present group from the 7th column of the previous group. Example: The range of my data starts from col F, then

F (7th) New Column (G) H (1st) I (2nd) J (3rd) K (4th) L (5th) M (6th) N (7th) New Column (O) P (1st) Q (2nd) R (3rd)

So, New Column (O) = N - F
and the next New Column (W) = V-N ...

NOTE: Column G can be ignored.

I want to add a looping function to this so that it will continue to subtract for the other respective columns as well. How do I incorporate this into the following code?

[Code].....

I'm using Excel 2013.

Filter Column Of Dates By Hour Of The Day

Jul 24, 2013

I have a database that includes a column containing dates which include a decimal time value e.g 2013/07/31 16:14

VBA that will allow me to filter to the records where the time element of the date is between two values e.g. between 12:00 midday and 17:59.

There will be many thousands of records covering a wide time period, so the code needs to ignore the date part and just concentrate on the time.

Probably dead easy but it's 17:04 and I have brainfreeze.

Subtract Value In Column A If Between Two Numbers

Jul 30, 2014

I'm working on a budget and financial calculator

I've already got it set up to calculate my pay and deduct taxes and all my bill and tell me how much I have left at the end of the month, now I am trying to get it set up to tell me how much will be left out of each check I get based on what day my bills are due.

Essentially what i want is I7 is the cell for my first check of the month and K7 is my second check, Column H shows my due dates for each bill, column A is the price on each bill so what i want is something that is similar to.

If the value if column H is between 5 and 19 then deduct the price in column a from I7 (with H and A being the same row) and if the value of column H is 1-4 or 20-31 then deduce the value in column A (with H and A being the same row) from K7.

Another way to put it would be I7 gets deducted the value in column A if column H is between 4-19 otherwise do nothing (with H and A having same row) deduct the value in Column A from K7 if column H is between 1-4 or 20-31 otherwise do nothing.

Match Two Cells And Subtract

Aug 6, 2008

My workbook has 3 worksheets in it, Data Entry - Components – Jobs. The first worksheet contains 2 buttons to enter new data via user forms. The second worksheet has 3 columns in it, component code, date, quantity and they are populated via a user form. The third worksheet has 4 columns, component code, date, quantity and Job number and it is also populated via a user form. When a person enters the data into the job user form and then clicks the command button to add it to the spreadsheet I need it to also find the matching code in the component worksheet and subtract the job quantity from the component quantity. So if the component worksheet has Envelope1 with a quantity of 25,000 pieces and I enter a job that used 10,000 of Envelopel1 the component worksheet would be updated and only list 15,000 pieces.

Using one spreadsheet with three date columns and two columns counting days.

If there is a value in Resolution date, then Column N is blank
If there is no value in Submit date and Resolution date, then Column N is blank
If there is no value in Resolution date, and there is a value in Submit date, subtract Submit date from todays date to show how many days it has been pending approval

Created on = J4
Submitted on = K4
Resolution Date = L4
Days to Approve = M4 I've got that formula =IF(L4="","",L4-K4)
Days Pending Approval= N4 (cell with formula)

If Resoultion Date L4 has a value, return blank
If Submit on K4 and Resoultion date L4 are blank, return blank
If Resolution date L4 is blank, and Submit on K4 has a value, subtract Todays date from Submit on K4 to show Days Pending Approval
