Excel 2007 :: Calculate Time By Time Periods Splitting Productivity?

Mar 8, 2014


I am trying to figure a way to search for a cell that has a specific date and time range. There are several cell titles pending on the activity. I want to find a cell that has a time ** 7:30-15:30 , 15:31-17:30, 17:31-20:30. The end result is to calculate the activity between those time periods based on the data cells.


If the date searched time field ** the activity ranges is 1635 I need to split the time and credit the activity time in the 730-1530 time and the rest on the 15:31-17:30 time

I have been able to do it on a single labor group based on time alone, but when I try to add the DATE to it my numbers go null. Eventually i will need to add 11 labor groups daily for weeks at a time .

Count Number Of Full Time Periods Within A Time Period

Nov 18, 2008

I have thousands of timestamps that have a start & end date and time in 2 separate columns. (one named start and one named end...)

I also have numerous set time periods that i'm interested in.. (about a dozen or so)

for example 01/01/2008 - 05/01/2008, 07:30:00 - 10:00:00

What i need is to be able to count the number of times the full time period i am interested (07:30:00 - 10:00:00) in falls in between the thousands of start and end timestamps i have. The time periods must also fall within the date range specifed.

So if my timestamps were
Start: 01/01/2008 06:30:00 & End: 02/01/2008 11:00:00, based on the set time period above, there would be a count of 2

and if my timestamps were
Start: 01/01/2008 07:05:00 & End: 02/01/2008 09:00:00 there would be a count of zero as there is not a full uninterupted timeperiod 07:00:00 - 10:00:00 between these timestamps.

and if my timestamps were:
Start 01/01/2007 07:00:00 & End 02/01/2007 10:00:00 the count would be zer as this is a year early!

Convert 52 Week Rolling Forecast To Monthly Forecast

Apr 4, 2014

I have a 52 week rolling forecast that I would like to have displayed in each calendar month that it corresponds to. I have come up with a solution where it does lump the data together into months but it is not a smooth lumping of the weeks as some weeks cross over from one month to the next. Is there a way to lump each week into its respective month. My current solution places in some months 4 weeks worth of data and in other months 5 weeks worth of data. Attached is the spreadsheet that I am using. The tab "Weekly Sales" is the 52 week data which has specified the exact dates on the calendar that that week represents. The "Monthly Sales" tab has the 12 week data which has specified the exact dates on the calendar that that month represents. I've tried SUMPRODUCT but that is giving me 4 weeks in some months and 5 weeks in others.

I'm using this formula (below) to add the hrs between 2 time periods (4:30 pm in cell I37 and 8:00 pm in I38, then the formula is in I39) and works almost every time even when the second time goes into the am hours, except in certain instances such as: 4:30 pm to 11pm show as 30.5? But sometimes it shows the correct number, 6.5

Breakdown Time-periods To Hours

Aug 20, 2012

I have a source table that contains time information about shifts people work:


Source Table




Now I'm looking for way to 'enhance the resolution' of this information to an hourly basis.

This means I would like to know how many hours John worked on 1-1-2012 between 15:00 and 16:00 (0.75).

I probably need to add 24 calculated colums to the table corresponding with the hours of the day.

Extrapolating Revenue Over Various Time Periods

Sep 27, 2007

I have a spreadsheet that holds a list of customers and the contracts they have with my company - this sheet includes the Total Contract Value in s - so how much each customer will pay us for the service - the period of the service - so the start date of 01/01/08 to end date of 31/12/08 for example. What I then have is all the months across the top of my spreadsheet and I need to extrapolate the contract value, based on the period between the months.

Initially I had complicated formulas that simply divide the value by the number of months of the contract - however, my company has since changed the policy and requires it to be done to the day.

For example, if the value was 12,000 and the period was 12 months from 01/01/08 - to calculate January 08 it would be - 12,000 / 365 * 31, Feb would be 12,000 / 365 * 29 and so on...

Does anyone know how I can do this - bearing in mind that each contract won't be as easy as 12 months - it may be start date of 15/06/08 to 08/10/10 for example... If anyone can help me do a formula or formulae to calculate the value for each month - I would be very very grateful - as always... [/img]

Dates Distribution Between Time Periods

Aug 30, 2007

What formula should I use if I have a list of maturity dates and current investments amounts as of 06/30/07:

06/30/08 10,000
08/31/14 18,000

07/31/09 25,000
06/30/10 14,000
12/31/25 80,000

and the amounts need to be distributed in columns titled:

Within 1 Yr (From 7/1/07 to 6/30/08)
After 1 to 5 Yrs (From 7/1/08 to 6/30/13)
After 5 yrs (After 7/1/13)

2 Series Chart For Different Time Periods

Oct 24, 2007

I am trying to plot two data series in one chart. The first series has monthly corn prices for last 10 years (~130 data points). The second series has bimonthly chicken prices over the last 10 years ( ~72 points). How can I plot them together?
The bi-monthly periods for the second series do not exactly coincide with calender months ( e.g. Aug 19 to Oct 13, 2007). As a result, I can not adjust the points to match with calender months.

Match IDs Across Spreadsheets By Corresponding Time Periods

Feb 5, 2008

There are 2 seperate spreadsheets

S1 - "End"
No. | ID | Name | Login | Total | Jan-07 | Feb-07 | March-07 | => | Dec-07
S2 - "Datasource"
ID | Irrelevant Name | Period | State | Irrelevant Data

I need something to go through the unique IDs in the "Datasource" & find a match in the "End" spreadsheet & then insert the number "1" in the corresponding time period (matching Period with Jan-07 or which ever it's suppose to represent). The Period is written in the following format:

122007 for December 2007
12008 for January 2008

One thing, the datasource has dates for both 2007 & 2008. The end spreadsheet has 2007 in one worksheet & 2008 in another.

Formula To Count Number Of Times A Occurs Between Time Periods

Nov 30, 2013

I am attempting to create a formula that will count the number of times, lets say letter A, occurs in column E. However, the tricky part that I have been confused on is that I only want to count how many times A occurs between each hour of the day. I need to count number of times "A" occurs between each hour of the day for the entire month.

My Worksheet looks as such: Column A contains the dates for the month of November, Column B contains times that random instances occur, Column C is not important, Column E contains a Letter A-N that pertains to what occurred at a time in column B. SO, Column B and column E coordinate with each other.

Here is an example. Column A - Cell A1 - 11/01/2013 , A2 - 11/02/2013, A3 - 11/03/2013.
Column B - Cell B1 - 12:01 AM , Cell B2 - 14:03 , Cell B3 - 15:23
Column C - Cell E1 - A , Cell E2 - A, Cell E3 - B

So I would like Column F to display that between 12:00 - 12:59 Am there was X number of times the letter A occurred throughout the entire month.

Simple Supply And Demand Graph

Jan 30, 2009

Maybe the title shouldn't be simple or I am missing something starring me in the face.

I am trying to make a supply and demand graph, with the following table,

wage supply demand
45,000 200,000 325,000
40,000 220,000 310,000
35,000 250,000 300,000
30,000 290,000 290,000
25,000 310,000 275,000
20,000 320,000 250,000

I can make either a supply or a demand graph without problems, however no matter where I place the vaules, ie wage first, demand, then supply or demand, wage, supply, the graph will not work or look right. The wage must be on the left had side so that the graph complies with standard Supply and Demand. I also need to be abble to make another graph showing what happens with a wage cap.

I can do it on graph paper, put I can not find a way to do it using Office 2007 Word and inserting a graph option and using Excel.

Fomula To Calculate Supply Vs Demand - Stock

Sep 3, 2008

I have a spreadsheet which uses MS Query to import data from our MRP System. This Spreadsheet has all new orders and qtys required per sales order etc. Each Part number may have several sales orders and different qtys for each. I am looking for help to write a fomula which looks the required qty`s for each sales order & part and check another sheet which has all the avaliable stock to sell on it and populate a column next to the qty req`d with what if anything is available.
Both the orders sheet and the stock sheet are MS Queries which refresh at a given interval so cells may change position.

Cutdown Example of Orders Sheet.

Sales Order No. Part Qty Req`d
1234 Apple 12
6777 Apple 16
7989 Pear 4

cutdown Example of Stock Sheet.

Part Qty in Stock
Apple 12
Pear 3

Now the fomula should bring back the following

Sales Order No. Part Qty Req`d Qty Avaliable
1234 Apple 12 12
6777 Apple 16 0
7989 Pear 4 3

Calculating Averages :: Weekly Demand Of A Product

Apr 28, 2008

I am currently using the following formula to calculate the average weekly demand of a product:


It works fine, but sometimes the data I'm analysing doesn't span the full horizon (78 weeks). What I therefore want, is for the COUNTIF part to recognise the last populated Cell in the array, and to use the length of the array up to that point to calculate the average. Put another way, if I only have 52 weeks of data (the last populated Cell is $BF8), I want the COUNTIF to calculate based on 52 weeks and not 78 weeks.

Make Entries Into Time Log

Feb 2, 2010

I am creating a log to keep track of my start and stop times when I work on a project. I have two columns labelled START and END and I can use a macro button to make the current date and time appear in the cell under these headings. What I haven't been able to find is a way of getting the macro to move to a new blank cell ready to accept the next entry. For instance, move one cell to the right or move one cell down and one to the left.

Can anyone tell me how to do this? (recording it just names the cell so it always goes back to that named cell.)

Trying To Make A Time Schedual Between Two Sheets.

May 21, 2009

I am trying to make book to represent time frames from sheet 1 to sheet two. The times are at the bottom of the sheet represented by letters from the alphabet eg, A is 6:30 in the morning to 2:45 in the afternoon. B is 8:45 in the morning to 5:00 in the afternoon ect, ect . I need to have the time represented in color or maybe a diagonal line through the cell in sheet 2 where each letter and corrosponding time frames are. Eg, I have given an example of the time frame "A" in column C in sheet two. I will make a sheet for each day of the month, so all I need is an equation for row "C"(Monday the 16th) in sheet 1.

Anyway To Make Auto Fill Time Value Static

Jan 24, 2009

I have 2 cell, A1 and B1. When any data is entered into A1, B1 will display the time corresponding to when the data was entered.

I was thinking about function for B1 would be "=IF(A1="","",now()) ". It worked such that it will display the time, however the value in B1 will automatically update itself if I were to randomly input any data in any other cell too.

For example, I input "testing" in A1. B1 display "11:20PM". Ten minutes later, I input "hello" in A2. B1 now display "11:30PM".

Anyone know a way to stop B1 from updating? or only update when new data is entered into A1 only?

Multiple Pivots With The Same Row - How Do I Make Them Change At The Same Time

Oct 22, 2009

I'm using Excel 2003 for this project.

For example: -
I have 3 pivot tables with the same row 'Media' (TV, Neswpaper, Magazine) and each has count as the data field (number of people who read/watch) then each pivot has a different column, Region, age, ***.

If I change the row of the first pivot to only show TV, how do i code it so pivot 2 and 3 only show TV also? I may have upto 20 pivots inthe end.

I found the below code to do this for page fields but can't adapt to rows -

HTML Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)
Dim ptTable As PivotTable, ptItem As PivotItem, vFields As Variant, lngField As Long
On Error GoTo ExitPoint
vFields = Array("filed1", "field2", "field3")

Application.EnableEvents = False
For lngField = LBound(vFields) To UBound(vFields) Step 1
For Each ptTable In ActiveSheet.PivotTables
If ptTable <> Target Then
With ptTable.PivotFields(vFields(lngField))
.CurrentPage = Target.PivotFields(vFields(lngField)).CurrentPage.Value
End With
End If
Next ptTable
Next lngField
Application.EnableEvents = True
End Sub

How To Make Clock To Show Time In Words

Aug 29, 2013

I want to make a Word Clock. Instead of showing the time as "12:30" I want it to show the words "It is half past twelve"

To Do this I've created a Square of Letters on an excel sheet (one letter per cell!) with black letters and black back grounds, when it is 12.30 I want the relevant letters to (cells) to change the text coulor to white so it shows up.

The cell I'm using are from D8 to P19 and the time is shown in A1

So lets say at 12.30 Cells D9, F12, H14 and M16 need to change from Black Text Colour to White Coulour,

I need a code or some VB that says "If A1 = 12.30 the Cells D9,F12,H14,M16 = White Text Colour, if not Black Text Colour".

Join Numeric Cells To Make Date & Time

Jan 2, 2007

I am using this formula to combine Excel Dates & Times which is in seperate cells.
day Month Year Time

and trying to convert to Numerical Time for further calculations.
I have tried many Format variations but nothing seems to work.

It will show the correct Numeric Time if the Formula: =NOW() is used in Cell K12
But it won't show the same from the imported data that is Text format
in Cell I 12

The sample W. Book shows a better explanation of the problem.
The end result is to show how much time has lapsed in Cell M 14 by converting Time to Numerical and simply do the sums. Works otherwise but not in this instance.
The reason to trigger various macros according to pre-set Time Limits Etc.
