# 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.

## Calculate Working Days Left In Current Month

Aug 19, 2007

Is there a formula to calculate the working days left in the current month? I work in the financial services industry and am putting together a spreadsheet to automatically calculate sales production needs per "working day", based on my businesses schedule.

We are open M-F and Saturday, not including holidays. Now, I can look at a calendar, count the days left and put them in to the spreadsheet, but I'd prefer to have it calculate automatically.

On my spreadsheet, I have used the =TODAY() formula. In the cell below, I would like to have it calculate the actual working days remaining in the current month.

Since today is Sunday August 19th, I know that there are 11 working days left (starting Monday 08-20-2007). Is there a way to get Excel to do that?

## How Do I Create A Running Average That Will Only Calculate The Averages In % Each Month

Mar 20, 2008

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%.

## 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.

## Formula To Calculate Days?

Apr 22, 2014

I am currently using the following formula which has been working great for what we needed it to do:

=IF(ISERROR(NETWORKDAYS(O34,Q34,Holidays!C\$2:C\$20)-1),"Not Completed",NETWORKDAYS(O34,Q34,Holidays!C\$2:C\$20)-1)

The formula determine what was been completed on the previous work day. If it fell on a weekend or a holiday specified in another table, it would consider it the following weekday's work. However, the needs of management have changed and they would now like to see anything completed on a weekend or holiday push back to the previous weekday and I'm not exactly sure how to modify this formula to do that.

As an example, work was completed over Good Friday. Yesterday (Monday) when we ran the report, none of those showed up in our list of completed items until today (Tuesday). They would have liked those numbers to be included on Monday's report to get an accurate picture of work that was completed.

I have attached some sample data. Everything completed on the 18th, 19th is counted as 1 day behind but we would like 18th and 19th to be shown as 2 days behind, just like April 17. That way, if we ran the report today and set the filter to 1 (for column C), those items would not show up, but they would have shown up on yesterday's report.

## Formula To Return Average Days Between Two Dates In A Given Month?

Jan 13, 2014

I have a workbook with two sheets. The first has a list of job positions open, columns designated to stages in the employment process and in these columns, my staff enter the dates that they completed a particular stage.

"Position | Date Opened | Stage 1 | Stage 2 | Stage 3 | Stage 4"
Pos 1 | 01/01/2014 |02/01/14|03/01/14|07/01/14|09/01/14

This has a great number of entries and they are increasing and decreasing every day depening on the amount of jobs available.

On the second sheet, I am trying to set up a table which shows the average working days it is taking to complete each stage, divided into the months in which the job position was opened (i.e. for positions opened in january, the average completion working days for stage 1 was X amount of days etc...)

I have tried using =IF(AND(Logical, Logical),TRUE,FALSE) but this doesn't return any info as the logicals will always be false. I tried the OR function, but that requires only one of the criteria to be true to return a value. What I need is for the formula to return a number of days between two dates, ONLY if the opened date falls in one month.

As you can see this also laps into a new year, which poses my next problem, ill probably just add more columns on to the end of the table for that though...

I will later apply different calculations to these cells but in short need to get a calculation for the number of days per month first.

(in short spreading the new value out accross the year then multiplying it by the days... i also need to apply a further daily volume cal to it).

## Formula / Calculate Number Of Days Between 2 Dates That Equal A Given Value

Mar 19, 2014

I have two date columns, a start date and end date. Another columns tells me the number of days between these two columns. It may return 45 days which actually straddle 3 different months.

## 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.

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.

## 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.
