# Average Days Between A Range Of Dates?

Is there a way to calculate the average days between a column of dates?

Basically, I've got a sheet that contains a table of entries, and each entry gets a date stamp in the first column. I would like to have the sheet display the average time, in days, between entries. Is this possible?

Hello,

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:

01/01/2007
02/01/2007
03/01/2007

I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.

Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!

Many thanks,
Caitlin

I'm trying to format a worksheet to show how many days overdue certain tasks are, and running into a couple of issues. The sheet is set up with Due Dates in Column A, Days Overdue in Column B, and Date Completed in Column C. My first thought was just to use as simple a formula as possible in Column B =Today()-A2. This worked alright for tasks that already had Due Dates assigned, but if Column A was blank I'd get a high number in Column B. I also realized that tasks will continue to show as overdue even after I enter the completed-on date in Column C. Is there a relatively simple way to tackle this formula? Thanks in advance for suggestions. (I've attached an example with the column headings I want to use.)

I'm trying to come up with a solution to calculate the man hours and days worked over multiple sheets.

I have a file that has 8 sheets. the first seven sheets are the days of the week and the 8th sheet is where I want to calculate the hours.

The days of the week consists of "Name" "Date" Hours"

The 8th sheet consists of "Name", "Days of the week in their own column (7 columns in total)", "Total Hours" and "Total Days Worked"

Now... each day is always a different group and what I'm hoping for is to create a formula that can grab each name with their hours and throw them into the 8th sheet. So when the end of the week is done I have all the Employees weekly hours and days worked all finished.

I hope this makes sense. This file is to track about 100 employees that are on a rotational work schedule.

I have attached a sample file.

I am trying to calculate the average Talk Time into Minutes and Seconds. Every time I have tried, I get the wrong average.

For example, if I have a total of 53 calls and the total talk time is 4:19:05, what would the average talk per call be? I tried doing everything in seconds (this would give me a total of 15545 seconds) but the total I was getting is 4:89.

What would the formula be to get the correct average time?

Very new in this board. If I post this question in the wrong forum please bear with me.
There is about 20 staffs in our department and I have made a spreadsheet with 12 tabs for each month of the year Jan-Dec. If each staff have 15 days annual leave each year and how can I make a formular that can automatically calculate the balance of annual leave and entered in the tabs of the following months. For example if staff A used 5 days in Jan how can the balance of 10days be entered in the tabs from Feb-Dec. If he use another 5 days in July the remain balance of 5 days be automatically entered in the tab from Aug to Dec. Likewise if staff A took 2 days sick leave in Jan, and 2 days in Mar how can this sick days be automatically sum up in the months after. I am doing this manually at the moment and it is very time consuming and also very easy to make mistake.
Thanks and sorry for this long questions

Good afternoon!

I'm working with Excel 2003 sp 3 on Windows xp.

I have been banging my head trying to jar loose the formula to calculate man days where 1 equals 8 hours. I have one that was given to me by a coworker:

=INT(Q3/8)+(((Q3/8)-(INT(Q3/8)))*0.8)

That calculates man days from total hours. I need a formula that will total man days and return the man day answer. Example:

weekending 12/25 = 16.2 which is 16 man days and 2 hours
weekending 1/1 = 24.7 which is 24 man days and 7 hours

Total = 41 man days and 1 hour

I have also been asked if there was a way for a number to be entered into a spreadsheet and automatically put in order without a macro or "pushing a button".

Happy New Year!

I have a workbook that has compliance dates in columns "F","G" and "H" from row 7. What I need is when the date in either column comes within 30 days to auto send an email, address in column "A", recipients name in column "B". and then place todays date in column 'P". ALso need to send a follow up email when either date comes within 7days and then place todays date in column "Q". If there is a date in column "P" then don't send email. If there is a date in column "Q" then don't send follow up. Can this be done without the users intervention and each time the workbook is opened.
Thanks in advance for any assistance.

Hi

I have a table with various percentages, and I would like a formula to have an average of these. Please see attached file to get more of an idea.

Hi there

I am trying to calculate our On Time Delivery. I want this as a simple percentage of jobs. I have got this running in the following way:

Column M - Estimated Delivery dates
Column N - Actual Delivery dates
Column O - =IF(SUM(M2-N2)>0,1,0)

Then I have calculated On Time Delivery as: =SUM((SUM(O2:O252))/(COUNTA(N2:N252)))

This seems to work fine. My problem is, if we enter a date in Estimated without a corresponding Actual date, the formula for Column O fills out anyway and improves our On Time Delivery Percentage. How can I set this up so that the formula doesn't calculate if there is no data in Column N?

Any help much appreciated

Thanks,

A previous poster explained what I also need; there were no responses,
so I thought I would try again.

Does anyone know of an Excel template--or a small stand-alone
program--that will calculate the interest/principal breakdown when
payments are varied in amount and frequency? Free or low-cost, please.
I need one that will work on my Mac/Office 2004. I will need to print
out periodic reports.

Here is the way the previous poster described it:
"Excel template: Loan Amortization for random/irregular payments,
figures days
between payment dates.
I have a loan with a variable beginning balance and irregular payments
with
annual large payment. (based on collections)
Would like to enter payment and date.
then Excel would figure days since last payment, interest amount,
principal
amount, Ending Principal balance.
And total interest paid, total pricipal paid
If I change the starting principal, excel would recalculate all
entries."

Thanks very much.

I have a spreadsheet counting down the days until a date is reached. However, after that date is reached and passed I get a #NUM! error.

What can I do to countdown the days as below AND countdown the days that have passed as a NEGATIVE NUMBER???

=DATEDIF(NOW(),D11,"D")

Hi,
How to calculate average handling time.

From limited experience I know that excel calculates dates via serial numbers.

I have formulas to add a number of days to a cell containing an entered date and display the resulting new date (ie. 03/01/2011 (c34)+11 = 03/12/2011)

I am seeking to leave resulting formula cell blank until a date is entered in the input cell. Currently when the input cell is empty the formula cell obviously displays 1/11/1900 using the above example.

What conditional format would achieve leaving the formula cell blank until date data in entered into the source cell?

Hopefully a simpler question for your experience level than mine.

I have attached a schedule for shift allowance calculation. The conditions for payment are as follows:

3 & 4 shifts = 15% Basic
2 shifts = 10% Basic
If on leave for 21 working days or more, no shift allowance
If on leave for less than 21 working days and on 3 or 4 shifts, shift allowance prorated as (Basic*15%)/21*(diff. btw 21 and no of days leave observed)

If on leave for less than 21 working days and on 2 shifts, shift allowance prorated as (Basic*10%)/21*(diff. btw 21 and no of days leave observed)

The formular I used in the attached worked but the only problem is that I had to sort by no. of shifts and adjust the formular first. I need A formular that does not require sorting. I tried to combine IF, AND, OR formulae but I got error. Please assist me sort this out. Thanks a bunch.

HI...can anyone help me with a formula for aging data in days (to be aged based on current date vs. for eg., Invoice date)

Hi all,

I hope you can help me with what I would like to do. I've searched and searched and not come up with anything yet!!

I have one sheet which is my 'data' sheet with a number of columns, one of which is a date which may be repeated.

I then want to use another sheet with two cells where two dates can be entered and a button which allows you to copy the rows of data from the data sheet which have dates between the two specified originally. The list in the data sheet may not be in date order although I could update a macro to do this for me if needed. I would also like to do it so that if "ALL" is typed in the date fields, it pulls over ALL the data. (Or something similar)

Cheers,

Kevin

I am creating a basic accounting spreadsheet and I ask for assistance to automate data entry posts. I would like to have entries that are entered in the general journal automatically post to the corresponding ledger accounts. The entries need to remain in chronological order. Relative cell referencing will not work because the rows in the ledgers will not correlate to the rows in the journal because the journal but the entries in the ledger need to input on the next available row in that ledger account. Additionally, as the number of entries increase, can the ledger accounts add a new row?

Attached is a very simple example with three transactions. I have included an end state view in the ledger accounts tab.

So I am at work workin on this report and I need a function that will make Excel automatically insert the today's date in a cell (let's say D90) when I fill the content of another cell (for example C90) and the that will be inserted will never change. I tried to use the =TODAY( ) function but it keeps updating the date in the cell to the current date if i reopen the worksheet 2 days later. I need the cell to keep in the cell the date of the day when I filled in the content of cell C90 and do not updated it every time i open the document to the actual date.. Thanks in advance!!

I am using the following formula to calculate the number of days between a date and the current date: =DATEDIF(A1,TODAY(),"d") What do I add to the formula to leave cell blank if no date is entered in the cell for calculation.

Hey there,

I have been tasked with introducing userforms into an excel sheet and tbh I'm quite amazed that excel has this capability of adding userforms to excel sheets.

Anyway, I have 2 columns of data in an excel sheet and I wish to add this to a userform so that the userform displays the 2 columns beside each other with headings, like a table. The user should then be able to select a particular row and insert it into the specified cell.

I would also like the user to select a row on the table and then be able to bring up another table depending on the row selected...basically so that the user can draw deeper into the information that they require.

I have an example excel sheet where I have 2 sheets. One sheet is the user entry sheet called User Entry Screen. the next sheet is the tables sheet where my tables are held. Once the user selects the cell shown in the example sheet, it should then bring up the user form. the user then, depending on which item clicked, then gets shown the next window with a table and info on it. then user should then be able to select an item and the cells on the user entry screen would then get populated.

Personally I think this is a really tricky challenge and any help with doing this would be extremely appreciated.

I'll post up further comments as I am trying to work my way through it!

Thanks,

Jag

I am trying to automatically capture and record the date of a cell's last change in value (date stamp). I have an item price list and if a particular cell gets updated I want to automatically record the date of change of that cell. I realize that after I change cell A1 I could tab to cell B1 and enter Ctrl+; but if I have a hundred new prices to enter I don't want to do that (plus me or the data entry person might forget).

For instance,

A B
1 \$32.17 8/17/08
2 \$43.20 9/12/09

If I go in and update cell A1 to \$33.98 today I would like cell B1 to read 2/16/10. But I don't want cell B2 to change.

Thanks
