# Last Ocurance Of The Last Date Used For Each Month And Then Use The Cell Number To Calculate The Column Totals For That Month

Jan 28, 2010

I have a spreadsheet that is now a yeare old with 5000 rows and is now going into the 2nd year

Column A is for date input and the same date can be repeated several tumes :-

1 Jan 09
1 Jan 09
1 Jan 09
1 Jan 09
2 Jan 09
2 Jan 09
3 Jan 09
3 Jan 09
3 Jan 09

Sometimes there are all 30 /31 days but normally not .

I need to find the last ocurance of the last date used for each month and then use the cell number to calculate the column totals for that month.

## How To Calculate The Week Number Of The Month Based On A Date

Dec 30, 2013

I would like to calculate the week number of the month based on a date.

Now my days would only include working weeks (Monday - Friday).

Supposed the date is 12/31/2012:

M
31-Dec
T
1-Jan
W
2-Jan
TH
3-Jan
F
4-Jan

Since it only occupies 1 day of the workweek, then it will be considered as Week 1 of January. If the date is 1/28/2012:

M
28-Jan
T
29-Jan
W
30-Jan
TH
31-Jan
F
1-Feb

It will be considered as Week 5 of January since it occupies 4 days of the working week. If the date is 4/29/2013:

M
29-Apr
T
30-Apr
W
1-May
TH
2-May
F
3-May

It will be considered as Week 1 of May since it occupies only 2 days of the working week.

Basically if the date's month occupies 3 or more of the working days of the workweek then it will be considered as part of that month's working week. Is this possible with formulas? I tried to explain it the best I can.

## Calculate Number Of Days Between Two Date Within A Current Month Including End Date

Apr 2, 2009

I have two columns of dates, leave start and end dates (when people start leave i.e. annual leave). Would need to introduce column(s) to calculate how many days fell within the month including the end date and excludes weekends.

For example, if the staff on leave from 31st March to 6 April, i need to show that the number of leave taken as 1 day in March and 4 days in April.

## Calculate Number Of Dates Within A Column Based On Month

May 15, 2009

I have a column say column B for example that has a list of dates in the format dd/mm/yyyy. I would like a summary at the top of the columns to state how many dates there are for the current month. But I wondered if this was possible based on the TODAY() function or similar. Thus the user would not have to change anything.

So for example at the start of the month it may state 14. Half way through the month down to 6 and at the end of the month 0 for example.

## Reflect Month Name When Column A Date Is Same Day And Month

Jan 8, 2014

How to correct this formula to get correct output.

=IF(P9=TODAY(),IF(P9<>"",CHOOSE(MONTH(P9),
"January","February","March","April","May","June","July","August","September","October","November","December"),""))

It's working fine if the year is 2014 but not if the year is different.

Conditions:

If the date is today then only the month should display else blank. The year should be ignore.

For example:

08/01/2000: January
01/01/2000: blank cell
08/01/2014: January
01/01/2014: blank cell

The date is in column 'p' in dd mm yyyy format. In short if the date is current date that is for today '8' then only the month should be display in the output.

## Using Offset From Latest Month To Calculate 3-month Average Within A Range

Jul 1, 2009

I have a spreadsheet that has columns of monthly values for three years of financial data and where the values for the latest month are added to the last column. Months that have not been completed will have a zero value (e.g. Jul-09).

Jan-09

Feb-09

Mar-09

Apr-09........

## Return Month Number Of Date Unless Cell Empty

Apr 9, 2008

I am using the MONTH function in a formula. The Month value of an empty cell is returned as "1". Why is this? Is there any way to return a null value or zero?

## 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 The 6th Month From Start Date?

Dec 25, 2013

I need a formula to calculate a date 6 months forward from the start date. However, in the calculated 6th month, I need it to the day before the start date.

ie: start date: 26/12/13 -- End date: 25/06/14

## Calculate Date Of First Business Day Of A Month

Sep 19, 2012

I am attempting to create a formula that will select a value from a lookup table where that value is related to a specific date BUT that date, derived from an input date (any day within a selected month) must always be the first BUSINESS day of that month.

For example:

I have a workbook with two worksheets in it.

The first worksheet is the input page.

On that page I want to have a list of dates which display the FIRST BUSINESS DAY of a month - e.g.

Cell A1 - Date entered as 19/9/12 and displayed as 19-Sep-12
Cell B1 - NEEDS THE REQUIRED FORMUAL TO CALCULATE THE FIRST BUSINESS DAY OF THIS MONTH (SEP)
(in this example, this should be 3) and displayed as 03-Sep-12
Cell C1 - Will display the value from the lookup table on worksheet 2 (see below) related to the date in B1

The second worksheet is a lookup table containing a sequential list of dates from 28-Jan-69 through to present (19-Sep-12) in Column A.

The adjacent column B contains the related value to that date (the value being a foreign exchange rate) - e.g.

Daily
Date
USD

29 June 2012
1.0191

1 August 2012
1.0507

[Code] ........

Worksheet 1, Cell C1 should display the value of 1.0266

## Calculate Number Of Calendar Days For Each Month?

## How To Calculate Average Of Values Against Selected Date Of Each Month Within Date Range

Jan 2, 2014

I have a table that looks like this (its basically a historical data of a stock exchange):

Date
Index
January 4, 2010

[Code]....

The List continues till the current Date.

I want to calculate Average Index Values of a Date of each month within a Date Range.
Example: Calculate Average Index Values for 3rd of Each month from 1st Feb 2010 to 3rd Jan 2011. Formula should calculate Average of the Index Values for 3rd Feb 2010, 3rd March 2010, 3rd April 2010, 3rd May 2010, 3rd June 2010, 3rd July 2010, 3rd Aug 2010, 3rd Sept 2010, 3rd Oct 2010, 3rd Nov 2010, 3rd Dec 2010, 3rd Jan 2011.

Both the Date and the Date Range is variable. Also, the Index Value for selected Date of one or more month may not be available as that being a holiday. In that case, the formula needs to use the last available Index Value before that Date. e.g. If Index Value for 3rd Oct 2010 is not available, system will use the Index Value of 2nd Oct 2010.

## Create Year To Date Sales Comparing 4 Years Month By Month?

Dec 25, 2013

Need to create year to date sales comparing 4 years month by month. Stacked chart (Excel 2010) works OK for the first three months but adding the fourth month changes the chart to 4 series with a monthly axis. To put it another way I need a vertical axis of years and a horizontal axis of \$\$\$ with each months sales of each year stacked on its year.

## Date Function Query (calculate The Last Day Of The Month)

Nov 12, 2008

I am using a formula to calculate the last day of the month, using any date of the month in a worksheet in cell A13, this cell is also linked to another worksheet to pick up a date, using the ISBLANK function to prevent a dummy date entry appearing if the field in the linked ASHBY RISE worksheet is blank
=IF(ISBLANK('ASHBY RISE'!\$C\$5),"",'ASHBY RISE'!\$C\$5)

The last day of the month function is shown below
=DATE(YEAR(A13),MONTH(A13)+1,0)

This works fine if there is a date in A13, but returns a #VALUE! error if cell A13 is blank. I have tried using the ISBLANK function, but I am still getting the #VALUE! error. Of course I may have the sysntax incorrect.

## Calculate Year To Date Based On Known Month

Dec 6, 2009

I want to calculate Year To Data in B1 based on some data in C1 to N1. The monthnumber is located in cell A1.

There is of course several ways to do this, but is there a simple and easy formula one can use.

## Auto Calculate End Date Of Previous Month

Jan 28, 2009

I have a cell in which I will input the last day of a month (e.g., 1/31/09, 2/28/09, etc.) In another cell, I want Excel to show the last day of the previous month. Is there a formula to calculate this automatically?

I enter in Cell 1: 1/31/09
Excel calculates in Cell 2: 12/28/08

I enter in Cell 1: 2/28/09
Excel calculates in Cell 2: 1/31/09

## Calculate Date Of Next Occurring 3rd Friday Of Month?

Oct 18, 2013

I am trying to calculate the Date of the next occurring 3rd Friday of the month in relation to a Static Date in a cell. So if Static Date in cell is Tuesday of the second week of a month, then I am trying to return the date of the 3rd Friday of that month. If the static date in the cell is the third friday of the month, I just want to return that particular date. And if the static date is after the 3rd Friday of the month, I am trying to return the 3rd friday of the following month. So far here is the formula I am using:

Code:
=DATE(YEAR(A2),MONTH(A2),14+CHOOSE(WEEKDAY(DATE(YEAR(A2),MONTH(A2),4)),2,1,7,6,5,4,3))

The problem I have is that if the static date is after the third friday of the month, this continues to return the 3rd friday of the month of the static date and does not advance to the third friday of the following month. Looks like I cannot attached a sample spreadsheet but here is a screenshot of the sample sheet:

## Formula To Calculate Date End Of Prev Month

Feb 22, 2008

I have a worksheet where the current months date is entered in cell E1 (format dd/mm/yyyy) , using an input box.

I need a formula the will calculate the previous months month end date in cell A6 and the month end prior to the date calculated in A6 in cell A13.

where the dates start with 31 for eg 31/01/2008 , then my formula works, but if it starts with 30, 29 or 28, then obviously it does not work.

I would like a formula that will calculate these previous month end dates correctly.

See example below ....

## Date Range Formula: Beginning Of Month To End Of Month (which Is In The Current Row)

Mar 20, 2009

I have log data in two columns:
Column A: Date/time (at 30 minute intervals)
Column B: Numeric data

On the last row of each month, I’m trying to perform a SumProduct on the two columns and display that result in column C.

The end of the range is determined by the month in the current row.

I’m having difficulty finding the beginning of the range, though. I need to account for both the normal dynamic calendar days & the fact that I may get data starting mid-day and mid-month.

I have this formula, but I’m not sure how to make the first array dynamic or if this is even correct approach.

## Financial Model (formula To Equally Distribute Revenue Either Over The Next 1 Month, 2 Month Or 3 Month Period Depending On Size Of The Deal)

Dec 23, 2008

I m trying to write a formula for my financial model. If anyone can take a stab at a solution. I'm trying to write a formula that will equally distribute revenue either over the next 1 month, 2 month or 3 month period depending on size of the deal.

Details:
Sales will fit in 1 of 3 categories. Less than 25k; between 25k & 100k; greater than 100k.

- if under \$25K, recognize in next month (month N+ 1)
- \$25K-100K, recognize in two equal parts in months N + 1 and N + 2
- over \$100K, recognize in three equal parts over 3 months
N + 1, N + 2, N + 3 ...

## Excel 2007 :: How To Convert Month Number To Month Name

Feb 16, 2012

I am trying to add a dynamic date rang to the heading of a table. I can find the earliest and latest dates, and want to concatenate them in the heading...

January 1 2012 to January 31 2012

The day and year (and the other bits) are easy, but is there an easy way to convert 1 to January, without going through a vlookup.

## Dates - Show Month Only, And Actually Be The Month Only (not Just Format The Date)

Jul 28, 2008

I have a range of dates from 2003 to 2012. I formatted them to the 'Mar-01' option, but when I want to pivot on the month, Excel still reads them as the date - example 3/25/2008, 3/28/2008...and so my pivot table has multiple columns for all of the dates present in that month.

How do I truly format my dates so that excel reads them as the month only so that I can then pivot and show 12 columns (months) per year?

## Calculate Which Relative Month Row Compared With Today Date

Jul 9, 2013

I have a spreadsheet and every row has an incident date. What I would like to do is calculate which relative month it is compared with today's date. I know how to show if it is in the current month, but what I want is something like the following:

Today's date is 9 July 13

Row 1 date = 9 June 13, hence calculation = -1
Row 2 date = 17 May 13, hence calculation = -2
Row 3 date = 29 Jan 13, hence calculation = -6
etc

Some sort of month to month comparison resulting in an integer.

## Using Month Function To Obtain Month And Copy It To Next Empty Column

Apr 4, 2013

I am working in a spreadsheet that contains a bunch of data, it is not limited, and varies. It has some fiels such as: name, date of birth, address, and others. I am interested in creating a column with only the month digit of the date of birth for each row.

I have been working with some code, I am not quite sure how to continue. The following table would be a example that I have of the data, it has only to entry in the column of Date of Birth, but my data range will always vary. I want to get the month and past it in the next cell that is available in this case would be column c or 3... The worksheet name is REP.

VB:

Dim Cell As Range
' 1st cell with the posting date
Set Cell = Range("A2")

Do While Not IsEmpty(Cell)
If Cell = "Date" Then

## Calculate Sum Of A Column If Month And Year Is Correct

Jun 19, 2014

So yesterday I created a thread [URL] ..... that would clear a specific content if a date (or rather a day) matched the criteria.

Today I'm continuing with that document and need to sum the columns if the date in a row is the correct month and year.

Ex. Row 1 contains the date "yyyy-mm-dd" and row 2-5 contains empty cells or the value x. The x values are all random placed.

So, I want to sum all the "x" for February 2014.

I'd rather use a formula here than a macro/VBA-code but anything will do. I have tried myself with =sumifs and =sumproduct but with no success.

See attached file for example and for my =sumproduct formula.

## Adding Or Subtracting One Month To A Month Number

Nov 12, 2009

I have forumlas that will look at this cell and take action of the month in a different cell is either 1 month greater (Frontmonth+1) or less (Frontmonth-1) than "Frontmonth". As we approach December I'm realizing that logic will breadown since the FrontMonth+1 would be 13, not 1 (January)

Is there a way to get excel to add 1 month to just the month number so that if Frontmonth = 12, Frontmonth+1 would return 1, not 13?

## Month(Date): If The Month Is Not January It Works

I have a problem calculating something that happened last month if the month is january. At the moment, if the month is not January it works:

## Formula To Calculate How Many Days In A Month And Create Column For Each Day

May 18, 2012

Formula which can calculate how many days in a month and create a column for each day. Columns for day 28, 29, 30 or 31 also need the formulas in columns 1 to 27 copied over automatically. [sheet name "LARSheet1 to 1" ]

I'm trying to build "Leave, Attendance Management" system using Excel. I am about 40% there so far.

The basic structure of the workbook is as follows:

12x main monthly "Leave Attendance Record" worksheets (i.emonths April 2012 through to March 2013). [I will refer to these sheets asLARSheet1 to LARSheet12 ].
1 x worksheet which holds "data validation" list andvlook up info. ["FormulaListSheet"]
1 x worksheet acting as a database of staff details andpay numbers. ["StaffdBaseSheet"]
1 x summary page which shows staff reaming leaveallocation. ["SummaryLeaveSheet"]

What I'm having problems with at the moment is as follows:

A formula or a macro which works out how many days are present in a given month [starting date of month located in CELL B10].

Days 1-27 will be already set up on the sheet. Based upon the monthly value I would like a solution which can calculate how many days are in a month and create a column for days 28, 29, 30 or 31 (depending on the month).

I would like it to work like this:

When the user opens a new worksheet, they first entre the month start date in CELL B10. Hopefully this will trigger columns E13:AH22 to update with the relevant week day & date.

I also need the formulas and formatting in cells AH13:AH100 (column for day 27) to copied over automatically.

## Updating Totals By Month.

Oct 22, 2008

I have a file that tracks the number of days my employees take off each month. I want to be able to go back 6 months on a rolling basis to get the total number of days taken off.

I am trying to set my file up so that I can type in the month in cell R1 and have column S update for each employee with the total number of days he/she has taken off for the past six months. For example, if I type in OCT in R1, I would like to see S2 change to 6 and S3 change to 2.
