Calculate Business Days In A Month.

Hello,

I am trying to calculate business days in a month. I know I can use NETWORKDAYS to remove holidays, but I don't have a end date for each month, just the start date. Each date for example is 1/1/2010, 2/1/2010, etc... I don't want to manually go in and fill in the end date for each month, so I am trying to find a different way.

For the start date of each month I just start for example with 1/1/2000 and then copy down below with that EDATE(A1,1) then then just copy down so it keeps adding a month and to save calculation time I just paste special value after to update it permanently and not have to have it recalc.

I know I have to add the holidays to the network days function.... unfortunately. Unless there is a way to fill the US federal holidays automatically.... but even if so, that would be a pain because if for example July 4th falls on a Sunday, everyone gets Monday off. I guess it may be possible to somehow calculate all federal holidays, but Im sure I'd have to pull from a external source and I think the time spent writing that would be more of a pain than doing it by hand, and I'd have to add if it fell on a sunday, to give Monday as a holiday.

Anyways, basic idea is, a way to provide me # of buisness days without manually having to enter a end date for each month using NETWORKDAYS. EDATE works half way for the end date... for example I can start with 1/31 then EDATE + 1 to 2/28 because excel knows there isnt 31 days in feb. But then to continue every day for the rest will show as 3/28, 4/28 etc.... how can I change that to the last day of that month?

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 need a formula to calculate Turn Around Time. Find below the sample data and details for your reference.

Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday

If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.

In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.

Please let me know if you need any more details

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


I have a graph with various information in it. One is a line graph that tracks hours used in that department per month. The problem is that when it gets to the last month, and there is not yet data for future months, the line goes down to Zero (leavin this big diagonal line that makes the data look funny). I need this line to stop on the last month there is data for. (I do not manually enter the data, it is a formula that I do not wish to delete.) I know I can manually move the data that the line is pulling to make it stop on the last month, but I have a graph for 36 different departments and that's a pain to have to manually adjust 36 graphs each month. Is there a way to tell the line to stop if there is no data? Thanks!!


Hello, please help me out with this one.

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 was able to convert start date and and end date to the number of days
inbetween the two dates. Does anyone know how to then convert the number of
days into months?



Newbie here and I don't know where to start... I'm trying to set up a macro to when data is pasted to a TEMPLATE worksheet tab it will automatically copy and paste data to another sheet based on the month value.
For example:
If data contains 06/01/2011 in cell A1, then data needs to be pasted to "Jun" worksheet within the same workbook.

Can someone assist or can give some direction? Thank you


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")


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?

Thank you 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.


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.

Thanks in advance for your help.


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".

Any advice is greatly appreciated!

Happy New Year!

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)


I have a template that automatically populates the date field with the
current date when opened, using today(). Users then Save As to have an
archive copy of their spreadsheet. However, when they go back to access
their saved sheet, the date changes from the created date to the current
date. How do I stop this in Excel?

I know that Word lets you do this by changing the code from {DATE} to
{CREATEDATE}, but I can't find a similar setting in Excel.

Please help and thank you!



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.

Mick


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.


In Excel I have been trying to find an easier way to calculate a time
difference where the times cross midnight. Example:
Start time: 23:50:00
End time: 00:15:00

How would you formulate an equation to determine the duration of time or
differnce between the start and end time?



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.
