# 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.

I collect unique prices each day. I am trying to find a way to determine the average of the numbers collected from the 21st of the previous month to the 20th of the current month. This formula will need to calculate for multiple months and years. So for example, I need Feb2008 average-which would be the average of numbers found between Jan21-Feb20, I then need Mar 08 average which would be data from Feb21-Mar20 etc. My spreadsheet is setup with the first column having the dates (ex. 01/01/08, 01/02/08 etc) and the second column containing the value for that particular date ($2.85, $3.00 etc).

As the number of days between the 21st and 20th change each month, I just can't seem to find a way to do it without a whole lot of manual effort.

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........

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.

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.

I'm having difficulty understanding this concept, more so the formula.

So to figure out the MTD for Day 1,2,3,4, how would it be?

I want each day to have a MTD

etc.

Day 1: 33,966,611.42

Day 2: 33,966,611.42

Day 3: 33,966,611.42

Day 4: 34,074,098.36

I've created a User Form to input data on a dashboard where you can select a date from a dynamic list of dates. The list of dates is calculated using:

Code:

=(TODAY())-WEEKDAY((TODAY()),1)+2

The other dates are based on this date -7.

The User Form code:

Code:

Private Sub CommandButton1_Click()

Dim emptyRow As Long

'Make Sheet30 Active

[Code]....

This works perfectly for any date except dates from December. 3/12/12 (3rd Dec) turns to 12/3/12 (12th Mar) when it's copied to the cell. The same happens for 10/12/12 - becomes 12th October instead of 10th December.

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

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

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.

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

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:

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 ....

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.

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.

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.

=IF(OR(MONTH(A1009)=A4)*(A$4:A$65536

I have a worksheet that has all weekday dates in column 1 and values in column 2. I want to create a 30-day moving average based on the last (non-zero) value in the column 2.

Since every month has a different amount of days, I want it to search the date that has the last value (since I don't get a chance to update it daily) and go back thirsty days from that date and give an average of all the column 2 values skipping and values that are null or zero.

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)

Having trouble working out a macro for this...

Column B with dates and column C with values. I'd like to make another column with the cell value averages based on the date. In essence, calculating daily averages. In turn I will later be adapting it to go through the all sheets in all workbooks.

Ive looked at Arrays =SUM(IF(MONTH($A$2:$A$6)=1,$B$2:$B$6,0))

to determine the number of 1st Mondays or any weeday e.g. 5th Fridays between a date range e.g. 1/1/2006 - 4/1/2006.

I've noticed a lot of threads for calculating just one month but none for a period of time.

We have arrival dates and departure dates for guests and would like to figure out the number of meals needed on a particular date.

Named ranges: NumGuests _ArrivalDate _DepartureDate _CheckInTime _CheckOutTime

Need number of breakfasts

Number of Lunches

Number of Dinners for a given day of the week.

So if a guest is here say Jan 25 arriving after 9am, staying 2 nights they will have Lunch and Dinner on the 25th, BLD on the 26th and BL on the 27th. Since by default most arrive after 9 (miss breakfast), we can eliminate the checkin time for the breakfast calc and make the first one for the next day.

There might be other guests staying through that time period. The ******* would like to know how many meals they will need to prepare for the week.

I've tried everything from sumproduct to vlookups and can't seem to get it right...

I need to compute the number of days that a given range of dates has in common with any given month. So an example might be:

Cell A1: Range Start Date (say it's 1/1/07)

Cell A2: Range End Date (say it's 2/15/07)

Cell A3: Month Indicator (say it's 2, meaning February)

Cell A4: Days of Intersection (should be 15 in this case, meaning that 2/1-2/15 were the days of February that were also in the range 1/1-2/15)

Cell A4 is what I'm trying to create the formula for.

I'm in Excel 2000 and am having trouble installing the add-on.

I need to do the following and can't figure it out. How do I create a running average that will only calculate the averages in % each month. Example: Opt 1 for Jan, Feb, Mar =1 each= 3 total = 100%; OPt 2 for Jan, Feb, Mar =1,0,1= 2 = 66%; Opt 3 for Jan, Feb, Mar = 0, 0, 1 = 1 total = 33%. My problems is I want monthly running average that shows the yearly percentage up to date but only for the months there is a value 1 or 0. How can this be done because the way I have it now, those % are being divided by 12 and that isn't the correct %
