# Average From Whole Months Data Taking Exact Date To Start With

Jan 7, 2014

In the file attached there is only the data to look at, though file is little bit lager.

Now in cell G10 I've got the stock forecast in 3 months time, this stock forecast is calculated from a date rounded to the closest month (according to my criteria), then the formula looks at the reference number cell D1 to work out the formula. All the steps are in the file.

In order to be more accurate my boss and I want to use the exact date, so that delete all the round month process. My intention is to use the day of the date and then make a fraction of the months to calculate the average. Taking into account that a month have as an average of 30.4166 days.

In the file I did an example, to clarify my messy explanation.

Cells B2, C2, D2 won't be needed in order to do so.

Please have a look at the file. At the end my intention is to to such a formula or a similar one. The formula should be an automatic one when typing dates in cell A10

The result of it is in row 31 and 32.

## Return Months Between Start Date & End Dates

Jul 6, 2007

I have been trying to search for either a function or VBA that will perform the following:

If I enter I want all months >=1/1/07 and <=3/31/07 it would tell me that the months in between are January, February and March and so on with all dates.

## Calculate What Months An Employee Worked By Start And End Date

May 15, 2009

I am working on a sheet that will allow a user to enter a start month (from a pre-defigned drop down list) and an end month (again from ddl). What I need to calculate is in what months the employee worked in so I can calculate their salary cost by quarter.

It can populate other cells in order to do the calculation if needed. So, for example if an employee started in May, and worked until December, I need to calculate that he worked 2 months in Q1, 3 months in Q2, 3 months in Q3, and 0 months in Q4. Our fiscal year is April to March.. ;-) I have thought of several options, but none of them have worked 100%.

## Taking Average Of Grades?

Sep 23, 2013

I need to calculate the average of 5 grades from A,B,C,D, and E. However I want it to the average even if any number of grades (i.e. up to 5) are entered.

e.g

grade1 grade 2 grade 3 grade 4 grade 5
A A C B E

I have assigned a vlookup table to convert to numerical values, and got it to calculate the average, but it falls apart when any grade is missing.

I have used the iferror command on the different calculations, but when i put them to gather into one large string, again it falls apart.

## Taking Mean Average Of Sales From Multiple Workbooks

Mar 8, 2014

I am needing to create a table where one of the values is the mean sales from the last 3 months. Each month is in a different workbook. Each workbook is labeled "1 - Profit & Loss" where 1 is the month up to "12 - Profit & Loss". So each new workbook I create (save as and rename the month) I need it to update the workbooks it looks at.

I also am needed in another cell of the table the same month of the current workbook but exactly one year prior.

I am not at a full year yet, so until there are exactly 13 workbooks (where the 13'th can look back at the 1'st) the second formula should just display "No Comp"

## Filter Data By Date Within 3 Months Of Today Date?

## OFFSET With Today's Date To Show Last 6 Months Data

Dec 16, 2005

I have a data table with monthly data in columns (65 rows deep), with the months (in format dd/mm/yyyy but showing as Dec 05) running across Row 4.

I want to be able to use OFFSET to identify the current and previous 5 months, in order to dynamically chart various items in the last 6 months worth of data.

The charting bit I'm okay with, and I realise I need to assign Names for this to work, but I'm struggling with the OFFSET & date combination.

I have the following but it starts from a defined reference cell;

=OFFSET('BO Data'!\$L\$4,0,('BO Data'!\$4:\$4)-1,1,-6)

## Compare 2 Sets Of Data According To Start And End Date Column?

May 26, 2014

In my attachment I am trying to identify rows within Table 2 that do not fit in with Table 1. For example in Table 2, Row 16 has a Start Date of 17.11.2010 and an End Date of 13.11.2011 for ID number 151. This record has to be shown as "OK" because it fits into the date range of Row 103 of Table 1 i.e. Table 1 Row 103 has a Start Date of 01.01.2010 and an End Date of 28.02.2013 for ID 15. In other words the Start Date of Table 2 Row 16 is GE the Start date of Table 1 Row 103, and the End Date of Table 2 Row 16 is LE the End Date of the same Row 103 of Table 1, therefore this reocrd is OK.

Row 14 of Table 2 needs to be shown as "NOT OK" because it has a Start Date of 12.01.2013 and an End Date of 31.03.2013 for ID 15 and this doesn't fit any date range of any Row in Table 1 for ID 15.

## IF Then - Using 12 Months - Ongoing Average

Mar 7, 2009

The formula works but under very strict conditions. The spreadsheet has columns for all 12 months, a yearly total and an average column. The �If � Then� is for the average column for entire year. No matter what the month it will calculate the average using the appropriate number of months to divide by, now here�s the catch; each previous month has to have a number greater than �0� and luckily I have but if a previous month has a "0" it blows the formula out of the water. I had to split the into IF-Then into two sections because of the embedding limitations so when I have a lot of items that I need to do this for you can see I am having to reproduce this formula multiple times and tracking gets a little confusing. Example......

## Calculate The Average Of The Previous 12 Months

Oct 14, 2009

I'm trying to make a formula that will calculate the average of the previous 12months. The goal is to tie the formula to a reference cell that contains a date. Each time the date is changed by a user the calculation will be updated accordingly. Here is the CSE formula that I thought would work:

{=AVERAGE(IF(\$B\$5:\$B\$53=B\$2,OFFSET(\$C\$5,(COUNT(C5:\$C\$53)-1),0,12,1)))}

I've also attached a sample file to illustrate the problem. The 'range' portion (\$C\$5,(COUNT(C5:\$C\$53)-1)[/b]of the Offset function was setup simply to get the 12 months which preceeded the reference date.

## Excel 2010 :: Data Validation Won't Accept Start And End Date From Cell Values?

Mar 16, 2014

Data validation in an Excel 2010 workbook.

I want the date input to be restricted a start date and an End date specified in two cells on the sheet. However, when I set up the Data Validation, ANY date will be accepted.

As an example cell Z1 contains the date 1/3/2014 and Cell Z2 contains the date 31/3/2014, so in the Data Validation box, the Start Date is referenced to Z1 and the End Date is referenced to cell Z2.

But I can enter 1/9/2020 and the Data Validation happily accepts that date.

## Calculate Weighted Average Of Prices For 12 Months

Jul 9, 2012

I wrote code that works just fine, however, I realized there were parts of the data I was using that had 0's in it for holiday.

Bottom line, this is code that calculated the weighted average of prices for 12 months (12 rows across) and Drows across. I'm trying to use the "do while is empty" approach but can't get the syntax to work. Here's the code

Code:
For r = 1 To drows
Totwavg = 0
Tothours = 0
priceavg = 0

For n = 1 To ncontracts

## Count No Of Unique Months For Finding Average

Mar 11, 2014

I am trying to calculate the average headcount for different categories (over a certain period of time, by product, by job type etc) and I want to do it using a formula instead of a pivot table.

I have this set of data with a detailed headcount for every month. And I can find out the total HC for different categories using sumif/sumifs but if want to find out the average for a certain period, I need to split that total to the number of months where I have a HC.

For example, if the HC per month would be:

May 2013 - 12
June 2013 - 10
July 2013 - none
August - 5

in a 4 months period I would have a total HC of 27 and the average would be 9 (27/3 - July shouldn't be counted). How can I get the average in a single formula?

Month
Type
L/H
Prod type
HC

## Compute The FuTure Date When Start Date,Lead Date,Weekly Offs,Leaves And Holidays

Nov 15, 2008

First and foremost I would like to congragulate you on this wondeful piece of code in the below link...

The query was to get a future date excluding Fridays and Holidays...

http://www.excelforum.com/excel-work...rkingdays.html

I have a similar query and therefore I pasted this link...

I actually wanted to get a future date using a Dynamic two day off as my the offs keep on changing as well as incorporate Holidays and Leaves if any..

Now Holidays would be official Public Holidays and
Leaves would be taken by the employee..

The code needs to pick the Leaves + Holidays and different offs maybe even more than 2 offs...

## How To Auto-Populate Date Range (working Days Only) From Start Date And End Date

May 25, 2014

I am now trying to create a excel macro to auto populate all the dates with reference to a start date and end date. The catch is that only working days are required in the range. My reference cells (start and end date) are in Sheet 1 while the destination cell range are in Sheet 2. The reason for creating a macro instead of a function is that the intervals between the start date and end date changes frequently (annual, semi-annual and quarterly) Best case scenario would be a button which I can just press after i input the dates to generate the range of dates in another sheet.

## Formula To Calculate Based On Start Month Number And Duration Number Of Months

Mar 14, 2014

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

## Calculate Next Due Date Based On Start Date Frequency And Current Date?

Mar 9, 2014

I'm trying to workout how to take a known initial date a repeating frequency and work out the next due date from today.

Example

Initial Date :- 1st of January 2014

Frequency :- every 5 weeks

Current Date :- 9th of March 2014

Next Due date should be :-12th of March 2014 (if I worked it out correctly from my paper calendar)

I want to use a cell formula to do this for different initial dates and varying frequency periods (the frequency will always be whole weeks i.e. 1,2,3,4,5,6,7,8,8,10)

## Creating View By Filtering 2 Columns By Date (both Within 3 Months Of Today Date)

Mar 20, 2014

Trying to do a linkback from another post located here but not having much luck doing it: [URL]

I'm working with 2 date columns and trying to filter a view to only include projects with dates within 3 months of today's date.

I've attached a current working file of the data and the end result i'm hoping to achieve via a macro of some sort.

I've manually got it to work via formula by inserting 2 additional columns (highlighted yellow) which determine if the dates "YES" fall in this 3 month time frame of "" blank if not.

create a macro which does all of this automatically without modifying any columns if this is possible
