# 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.

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 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

How to create a spreadsheet with what I think will be a very simple formula?

If date in B2 - date in A2 is 1 or less days, put a 1 in cell C2.

If date in B2 - date in A2 is 7 or less days but more than 1, put a 2 in cell C2.

If date in B2 - date in A2 is 30 or less days but more than 7, put a 3 in cell C2.

If date in B2 - date in A2 is 90 or less days but more than 30, put a 4 in cell C2.

If date in B2 - date in A2 is 91 days or more, put a 5 in cell C2.

OR

Another, maybe simpler, way of saying it is:

If date in B2 - date in A2 is 1 or less days, put a 1 in cell C2.

If date in B2 - date in A2 is 2-7 days, put a 2 in cell C2.

If date in B2 - date in A2 is 8-30 days, put a 3 in cell C2.

If date in B2 - date in A2 is 31-90 days, put a 4 in cell C2.

If date in B2 - date in A2 is 91 days or more, put a 5 in cell C2.

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'm trying to calculate the number of days between dates in column A and B. I've looked at the examples in this site and thought I used the formula correctly, but the cell returns an error message when I type: =DATEDIF(A1,B1,"D")

I am using the following to autofilter a column based on a month number

Worksheets("Data").Range("$A:$M").AutoFilter Field:=8, Criteria1:=Month(tempmon)

tempmon contains the month number (e.g 9 for september)

when I run this it filters but tempmon is equaling 1 when I know it is set to 9

i have tried

Worksheets("Data").Range("$A:$M").AutoFilter Field:=8, Criteria1:=Month(9)

Sometimes my due dates need to be on the 15th of the month, for which DLL and Donkey gave me: =DATE(YEAR(TODAY()), MONTH(TODAY()) + (DAY(TODAY()) > 15), 15)

This works great except sometimes the 15th is on a Sunday which means I need the result to be the 13th, and sometimes it's on a Saturday which means I need the result to be the 14th. FYI: I am a n00b..

I have a sheet with a date and the number of months on it which will change. I need the sheet to list the dates in a column for each month automatically: e.g. Two cells contain date “jan07” and the period “10” months. The rows A1 to A10 should have jan07…jan16 listed automatically. If I change then change the number of month to 11 I would like the rows A1 to A11 to update automatically.

I have been using Excel for a while but i'm kinda stuck at one point where i have to calculate the sum of the numbers corresponding to the month of the data.

Column 1 has all the dates in different months - in this workbook i've included only jan, feb and mar. The second column has the counts corresponding to the dates.

Now if a user inputs the month (1,2,3) number in F2, then we need to compute the sum of all the numbers from second column corresponding to the month in column 1 and display in cell F4.

how to make a certain type of date automate. It's kind of hard to explain, but basically, I'd like to make it so that when I enter a date in one column, another column will automatically populate with the 1st of the next month. For example:

If I enter 4/26/2009 in the 1st column, column 2 will read: 5/1/2009

If I enter 1/19/2008 .................................................. 2/1/2008

Also, it's very important that if the FIRST date is already the first of the month, then the second column will read the same. For instance: If I enter 3/1/2009 in the first colum, the second column will ALSO read 3/1/2009.

I have a worksheet of data I need to sum based on a monthly date range criteria onto a separate summary worksheet. Both are in the same workbook. I tried using SUMIF and SUMPRODUCT but can't seem to get the criteria correct when I add in LEFT into the argument for the date criteria "6/" or "06/". Here's where I'm at so far:

=SUMIF('2008'!E4:E149,(LEFT('2008'!E4:E149)="06/"),'2008'!I4:I149)

My table looks something like:

Log NoShip DateQty

000953/26/20085

000963/28/20081

000974/28/20081

000985/28/20082

000995/29/20081

001006/1/2008

001016/14/20084

001026/20/20083

The 6/1/08 entry is intentionaly blank to be filled in as the value becomes known and then the totals would of course need to be updated.

I am trying to calculate the number of days between two dates where the arrival date is in b5 and the departure date is in c5 for each month. I have been using the following formula =IF($C5="","",MAX(0,MIN(L$1,$C5)-MAX(K$1,$B5))) but when the stay is a full year it is giving me 365 in a single column. I think maybe I need to add in the number of days in the month but not sure how to do it.

I have a start date formatted as dd/mm/yyyy in cell A5

I have an end date formatted as dd/mm/yyyy in cell E5

In cell F5 I would like the result of the number of days between E5-A5 (Excluding weekends)

In cell G5 I would like the total number of days in the range F5:F25

In cell H5 I would like the total number of working days from A5 to Today

I am using the following formula to get the result in F5 etc

=SUM(INT((WEEKDAY(A5-{2,3,4,5,6})+E5-A5)/7))

I have copied this down and in the blank cells I get #NUM!

In cell F? were there is no date entered in cell E? I get a minus number (which I can hide using conditional formatting), but the minus number obviously has an affect on the result in G5, as cell G5 gives me #NUM! instead of the result for the current numbers in row F

I need to count when the following set of 3 criteria criteria are met:

1: The Assessor Initials = DS

2: the month = Mar

3: Check 4 Ranges = columns I, K, M, O

I've tried using sumproduct (sucessful for other data) but not able to get it to work with dates.

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'm looking for the formula to calculate the number of winter days between two dates.

Say, that I'm having:

- Winter season start date (say Dec 1st)

- Winter season end date (say, March 1st)

=> All the days which are between these two are considered winter days for any given year.

- Two different dates defining the beginning and the end of my PERIOD. The total length of the period may be more than one year.

HOW do I calculate total number of winter days for the PERIOD?

I'm new here. I've searched these forums in the past for help, but never had to post, i've always been able to find something by searching. However, this time I couldn't find anything that addressed my specific need so I figured it'd be worth a shot.

Alright, I have two sets of dates, and i'm trying to set up a formular that calculates the numbers of days from the first date range that overlap/fall within the second date range.

For example:

In A3 type "1/1/2006"

In B3 type "1/1/2007"

In C1 type "6/30/2005"

In C2 type "6/30/2006"

Now, in C3 i'd like to insert a forumla that tells me how many days in the date range of 1/1/2006-1/1/2007 fall in the date range of 6/30/2005-6/30/2006. Basically for this is should be half the year, however many days that is.

Is this possible with a formula?

I am trying to project the next 12 month-end dates, based on today's date. I can do that using the EOMONTH function ... see exhibit below ... present month, 1 month out, 2 months out, last month. However, this workbook must be sent to many people and many of those folks will not have EOMONTH functionality because that requires the Analysis Toolpak functions to be added in. How can I accomplish this using standard Excel functions?

Present Month >>> =DATE(YEAR(NOW()),MONTH(NOW()),1)

One Month Out >>> =DATE(YEAR(EOMONTH(NOW(),1)),MONTH(EOMONTH(NOW(),1)),1)

Two Months Out >>> =DATE(YEAR(EOMONTH(NOW(),2)),MONTH(EOMONTH(NOW(),2)),1)

Eleven Months Out >>> =DATE(YEAR(EOMONTH(NOW(),11)),MONTH(EOMONTH(NOW(),11)),1)

I'm working on more code to take data from hotel reports, compile totals and transfer data to several other workbooks. In prior instances, I'd been working with data that had been converted from Adobe .pdf format, so while the cell values appeared to be dates, they actually were text. I'd come up with a solution to find the first of each month in a column of dates and insert a row at that point. However, I'm now working on this with a system that actually outputs in Excel format. As such, the date column is actually normal date serial value, rather than text and my code doesn't work. What can I do to modify this snippet of code to find the first of each month and insert a row when the values in the column are actual date serials?

Here's the current code:

With Sheets("Sheet1")

For RowToInsert = .UsedRange.Rows.Count To 14 Step -1

If (Range("A" & RowToInsert) Like "*/01/*") Then Rows(RowToInsert).EntireRow.Insert

If (Range("A" & RowToInsert) Like TodayVisualMatrix) Then

Rows(RowToInsert).EntireRow.Insert

Range("A" & RowToInsert).Value = "Subtotal"

End If

Next RowToInsert

End With

Row 3 doesn't find anything because while they appear in that format, the value of the cell isn't */01/*....

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.

I have a Training Matrix with "Main", "Leavers" and "Reports" sheets. (can email it but can't upload it here; it's 534kb and I can't make it smaller)

In the "Reports" sheet I need to fill "Site Procedural Training" - "Number of people trained in period".

The periods are :

25/12/11 - 31/03/12

01/04/12 - 30/06/12

01/07/12 - 29/09/12

30/09/12 - 29/12/12

The source of data will be the "Main" and "Leavers". The data are dates in these sheets; each date = 1

The formula needs to look in to "Main" and "Leavers" and if it finds a date which fits in the required period in "Reports" then return it as 1. If it finds 300 dates then returns 300.
