Counting Occurences Of Months And Days Etc In A List

May 11, 2006

I have been struggling for almost 2 days with this problem.

I have a list of data, one column of which is the date displayed in dd/mmm/yy format.
This date will always be entered by users and is variable.

I can't find a way of counting the number of occurences of each month and each day that the date represents.

So, I want to know how many occurences of March, June, May, Septemeber etc are on this list and Mondays, Tuesdays, etc.

I have tried several posssible routes, DCOUNT DCOUNTA COUNT COUNTIF SUM. I've also tried separating the date out into days & months using the MONTH & DAY functions but this didn't work either.

It also apepars (shock horror) that Excel has incorrect date & day values because entering todays date in one cell (11/05/2006) and then using the DAY function to find the day of the week for this date produces WED when it should be THU. (My system date is set as 1 Jan 1900).

I feel that Excel can't separate the months & days away from the date, since the date is stored as a numerical value and not as we humans use dates.
The dates will always be manually entered by users, probably as dd-mm and Excel will automatically add in the year.

How can I count the occurences of each month and days of the week?

Needs to be tracked like this:


Basically I need to write it so that when A occurs it counts how many times B occurs immediately after, until the next A. Once that is figured out I should be ok counting double A occurences.

Counting The Number Of Occurences

Mar 3, 2010

I'm trying to formulate something that will count how many times say 5 comes up in a =randbetween(1,20) function. Of course if I do =(IF(A1=5,1,"") it will count it, but once the randbetween recalculates it will reset. Is there any way to do this so it keeps a cumulative count?

Counting Occurences Within Specific Date Range

Sep 14, 2009

Im looking for a formula that will count the number of occurrences of YES in column A between a specific date range (column B) BUT only if the it's categorized as "LAB" (column C).

Up until now Ive jerry rigged the spread sheet to do it with various filters, if, and countif formulas but Im looking for something that will fit in one cell and lower the overall size of the file.

To make it even more complicated Id like to feed the formula the date range information from another editable cell so that it can basically be queried for whatever dates my boss is concerned about at that second.

Counting Occurences Of Values Relating To Date Range

Oct 18, 2009

i have a spreadsheet that contains a column for each day and i need to input the count from another tab for certain data...example as follows:

column A shows types of fruit - apples, bananas or oranges, row 1 contains the date (todays date, weekdays only) - the count of each fruit needs to be entered in rows 2 (apples), 3 (bananas) & 4 (oranges) for each fruit for each date

i copy and paste a daily report into a new tab in this workbook -Raw Data (the data is always in the same format and the info i need is in column J...."555" = apples, "666" = bananas & 777" = oranges)

i have used the below formula which works:

apples =COUNTIF('Raw Data'!$J$5:$J$65536,"555") etc

however the daily report that is pasted into the Raw Data tab only relates to the current day (date is present in this tab in A1) do i get each daily column to only display a count if the date in row 1 matches the date in Raw Data tab A1?

also how do i keep the previous days' data to keep what the count was for that day (instead of counting the current count of the new data only relevent for today)?

Counting The Number Of Months

Dec 13, 2006

I am trying to calculate the number of months between two given dates.
The spreadsheet is basically about staff and their start and end dates.

For example start dates would be in colum A and end dates would be in column B (in dd/mm/yyyy format).

I am currently using the following formula:

It does return the correct results when the dates are the same e.g. start date = 01/01/2006 and end date = 01/04/2006 = 3 months.
BUT when I change the end date to 31/03/2006, it returns as 2 months.

Is there a way around this? I need a more accurate number of months (with no decimal places)

Date Differences In Days, Weeks Or Months

Jan 3, 2008

I've been racking my brain on this one for awhile, and I feel like I'm going the right direction but...

I have a list of dates like:

or maybe


...and I need to determine if the difference between them is daily, weekly, or monthly. There are 79 of these lists, on 79 different sheets so I can't visually peg them as daily, weekly, or monthly.

The way I have been looking at the problem is to calculate the number of months between the last & first dates and see if the resulting answer (+1) matches the number of actual dates, and so on...

Excel 2013 :: Autofill (for Days And Months) Not Functioning

Apr 3, 2014

I am using excel 2013 in my laptop (windows 8.1) after having upgraded excel 2007. Everything works fine during my daily tasks. Especially autofill which I use quite often works perfect.

At the same time I upgraded my girlfriends laptop (Windows 7) with the office 2013 (office 2007 was the older version) and somewhere there begun some isues. Autofill doesn't. Especially with months or days. I enter the value "Monday", I drag down (of course using the black filled cross down right of the cell) the cursor and all the cells get the value Monday. Even if enter the value Tuesday in the second cell and then try to autofill (having marked before both these two cells) I get the same results. Monday, Tuesday, Monday, Tuesday.

I tried to test the autofill with numbers. If i write only the one number (for instance the value "1") and then autofill, this doesn't work. It gives me the value "1" in all the cells. But if I enter the value "2" in the second cell, the autofill works fine (marking these 2 cells and then autofill).

We make some online courses using exactly the same excel exercise files. In my laptop everything works perfect.

Formula Showing Revenue Recognition Based On Days And Months

Mar 15, 2014

I know I will earn $5,000 of monthly revenue from a client. $5,000 is represented in a monthly revenue cell. I have 12 columns showing the 12 months of the year. There is an additional cell showing the customers implementation date.

If a company's implementation date is on or after the 15th of the month (example: 3/28/2014) then the next month (April 2014) is skipped and the $5,000 is returned to columns May through December. All months prior to May return $0.00. If the implementation date is before the 15th day of the month (example: 3/13/2014) then the next month (April 2014) and all months after will return $5,000. All months including March and prior must return $0.00. If the implementation date is unknown then 12/31/2099 would be in the implementation date cell and $0.00 is returned for all 12 months.

Essentially, if the implementation date is prior to the 15th of the month the revenue will show as of the following month. If the implementation date is on or after the 15th of the month the revenue skips the following month and will show the month after.

Calculating Difference In Months Between Dates / Ignoring Days And Years?
