I am trying to find a (reasonably elegant) formula to find out how often a date appears in a list of date ranges.
In my example I have 4 date ranges, defined by a start date (A2:A5) and by an end date (B2:B5). Below I have a list of dates for which I would like to know how often a date appears in any of those 4 ranges. The only solution I came up with was to check for each range if the date is in there. The formula becomes quite lengthy with the number of periods and is not flexible if more periods are added later.
Here the time periods:
And here where I try to retrieve the number of matches given a date:
My formula is here for B11 (yielding 3 given the input of 10/Sep/2021):
=IF(AND($A11>=$A$2,$A11<=$B$2),1,0)+IF(AND($A11>=$A$3,$A11<=$B$3),1,0)+IF(AND($A11>=$A$4,$A11<=$B$4),1,0)+IF(AND($A11>=$A$5,$A11<=$B$5),1,0)
Any ideas appreciated!
Using COUNTIFS:
=COUNTIFS($A$2:$A$5,"<="&A11,$B$2:$B$5,">="&A11)

I'm trying to put multiple rows which contain a date of the month between the first and last day of the month and I want to put them togeather as the first of the month dpeending on which month they are in:
for example; if they have the month of 12 i want to make them the 01/12/2020 if it was november 01/11/2020 and so on...
What i am looking for is to get three or more dates into a single one:
Date
03/12/2020
16/12/2020
27/12/2020
And make it:
Date
01/12/2020
Thanks for any help on how i could go about this, im struggling to find a solution
(I have tried text join and concatenate and neither work)
If you have Excel365 then use-
=DATE(2020,UNIQUE(MONTH(A1:A4)),1)
If you have dates with different years then try below formula.
=DATEVALUE("01-"&UNIQUE(TEXT(A1:A4,"mm-yyyy")))
Pretty unconventional way of doing it but works:
=EOMONTH(EDATE(AVERAGE(A1:A12),-1),0)+1
Where A1:A12 is a range of dates.
You have not specified well whether your dates are strings or actual Excel dates. Nor is it clear to me whether this is an example of a single cell in a larger row. The solution would be different based on the answer to these questions (which I do not have enough reputation to put as comments).
If you already have these values as dates put a new value in an adjacent column. Assuming the existing date value is in cell A1:
=DATE(YEAR(A1), MONTH(A1), 1)
However, if the date value is actually a string you will need to hard code the extraction of the values. Assuming, the are in fixed length strings as your image shows, with dd/mm/yyyy format:
=DATE(RIGHT(A1, 4), MID(A1, 4, 2), 1)
I have a cell G4 with date and time in a format (Text string):
1/29/2020 1:34:24 PM
I need to convert it to DATE formatted cell. How to do that?
I have tried to get numbers and convert them to DATE with this formula:
=DATE((MID(G4;SEARCH("/";G4)+4;SEARCH("/";G4;SEARCH("/";G4)+1)-SEARCH("/";G4)+2));(MID(G4;SEARCH("/";G4)+1;SEARCH("/";G4;SEARCH("/";G4)+1)-SEARCH("/";G4)-1));(LEFT(G4;FIND("/";G4;1)-1)))
So:
I am extracting year:
=MID(G4;SEARCH("/";G4)+4;SEARCH("/";G4;SEARCH("/";G4)+1)-SEARCH("/";G4)+2)
Month
=MID(G4;SEARCH("/";G4)+1;SEARCH("/";G4;SEARCH("/";G4)+1)-SEARCH("/";G4)-1)
Day
=LEFT(G4;FIND("/";G4;1)-1)
I am getting as a result:
1.5.2022
I need it as it is now, but output should be 29.1.2020 in this case. Later I want to get day difference two that way formatted dates. Is it possible to do it with formula without performing any other cell formatting operations?
EDIT:
I got it working, the only problem is:
How to extract number (year) after third "/"? My current formula is not correct:
=MID(G4;SEARCH("/";G4)+4;SEARCH("/";G4;SEARCH("/";G4)+1)-SEARCH("/";G4)+2)
It does not function correct in this case:
2/5/2020 12:21:05 PM
EDIT:
I did it this way (I also had to minus G2 - F2, to get days difference):
=IFERROR(DAYS(MID(G2;SEARCH("/";G2)+1;SEARCH("/";G2;SEARCH("/";G2)+1)-SEARCH("/";G2)-1)&"."&LEFT(G2;FIND("/";G2;1)-1)&"."&MID(G2;FIND("/";G2;FIND("/";G2)+1)+1;4);MID(F2;SEARCH("/";F2)+1;SEARCH("/";F2;SEARCH("/";F2)+1)-SEARCH("/";F2)-1)&"."&LEFT(F2;FIND("/";F2;1)-1)&"."&MID(F2;FIND("/";F2;FIND("/";F2)+1)+1;4));"")
You probably need to replace an order of day.month.year and "." to "/" if you are using different date setting (region). I have one setup, so this seems to work.
FYI DATES in excel are stored as integers. They represent the number of days since 1900/01/01 with that date being 1. TIME is stored as a decimal representing fractions of a day or 24 hours. 0.5 represents noon. 24:00 is not an officially supported time in excel, but will work with some functions.
The DATE Formula is looking for three arguments representing YEAR, MONTH, DAY in that order.
DATE(Year, Month, Day)
You need to pull the text from your string representing these values. I find it easiest to pull each one individually in its own cell to ensure the part of the formula is working first then copy and past that part into the DATE formula so the whole calculation in the end can be performed in one cell.
YEAR
To get the year use the following formula:
MID(G4,FIND("/",G4,FIND("/",G4)+1)+1,4)
MONTH
To get the month use the following formula:
LEFT(G4,FIND("/",G4)-1)
DAY
To get the day use the following formula:
MID(G4,FIND("/",G4)+1,FIND("/",G4,FIND("/",G4)+1)-FIND("/",G4)
COMBINED FORMULA
Place the above formulas into the date formula as follows:
=DATE(MID(G4,FIND("/",G4,FIND("/",G4)+1)+1,4),LEFT(G4,FIND("/",G4)-1),MID(G4,FIND("/",G4)+1,FIND("/",G4,FIND("/",G4)+1)-FIND("/",G4)-1))
Note the only cell reference in the formula is G4. The results of the formula are not in an Excel Date format. Change the formatting of your cell to meet your needs. In your case I would apply a custom cell format of d.m.yyyy
If you have TEXTJOIN,
=TEXTJOIN("/",TRUE,INDEX(FILTERXML("<a>,<b>"&SUBSTITUTE(SUBSTITUTE(TEXT(A1,"dd/mm/yyyy hh:mm:ss"),"/","</b><b>")," ","</b>",1)&"</a>","//b"),N(IF({1},{2,1,3}))))
Depending on your version it may need to be confirmed with Ctrl-Shift-Enter instead of Enter when exiting edit mode.
the reason the second did not work is that Excel actually changed it to a date and a date is a double, not text. So there are no / in the data. so we need to force back to the incorrect string.
Those for whom the TEXTJOIN function is not available can use this:
=DATE(FILTERXML("<DATA><A>" & SUBSTITUTE(SUBSTITUTE(A1;"/";"</A><A>");" ";"</A><A>") & "</A></DATA>";"/DATA/A[3]");FILTERXML("<DATA><A>" & SUBSTITUTE(SUBSTITUTE(A1;"/";"</A><A>");" ";"</A><A>") & "</A></DATA>";"/DATA/A[1]");FILTERXML("<DATA><A>" & SUBSTITUTE(SUBSTITUTE(A1;"/";"</A><A>");" ";"</A><A>") & "</A></DATA>";"/DATA/A[2]"))
I have a series of dates and values:
8.12.2018 12
5.2.2019 32
15.7.2019 89
I would like to use something like (SUMIFS(YEAR(A1:A3);2018) but it's not allowed.
I know, I could extract the year in a separate column, but here I want to ask, if it's possible inside the sumifs function?
Although I thought you couldnt, it has proven by #forwardEd, you can alter criteria in such a way to use SUMIFS, however, you could also look into SUMPRODUCT for this exercize:
=SUMPRODUCT(--(YEAR(A1:A3)=2018),B1:B3)
Assuming your dates are valid excel dates and not dates as strings/text then you can use the SUMIFS formula for a year as follows:
=SUMIFS(B1:B3,A1:A3,">="&date(2018,01,01),A1:A3,"<="&date(2018,12,31))
Basically the formula is saying sum all the values in B1:B3 where the date in A1:A3 is greater than or equal to the first day of the year AND less than or equal to the last day of the year. I choose to write the date using the date function as it is easier to recognize than the integer format of the date. If you want to write just the year as a criteria in say cell c2 then replace 2018 in the above formula with c2.
UPDATE
I have not tested it but since the default for a date without time is 00:00:00 it would mean the formula above would cut off December 31 with almost any sort of time associated with it. Therefor the better cut off would be less than January 1st of the following year instead of less than or equal to December 31st. As such you could revise the above formula to:
=SUMIFS(B1:B3,A1:A3,">="&date(2018,01,01),A1:A3,"<"&date(2019,01,01))
or
Where C2 is the year as an integer
=SUMIFS(B1:B3,A1:A3,">="&date(C2,01,01),A1:A3,"<"&date(C2+1,01,01))
Alternative approach (a little bit less elegant solution, but might be more clear to less advanced users):
=SUMIFS(B1:B4,A1:A4,">="&"01/01/2018",A1:A4,"<="&"31/12/2018")
I'm trying to count rows where the date in a Date column falls within a particular month. I've tried many paths but all result in an error in my formula. They boil down to me trying to do this:
=countIF(Month(SHData[#MS550]),MONTH(SHData[#MS550]))
My final formula will need to be more complex than that, but even something as simple as the above generates an error. I've also tried it with Text(Date,"MMMM") with the same results.
Would be easier with COUNTIFS but with COUNTIF you might count all the entries greater than or equal to the start of your chosen month, then subtract from that the count of all the entries after the end of your chosen month. Something like:
=COUNTIF(SHData[MS550],">42004")-COUNTIF(SHData[MS550],">42036")
for January this year, if using the 1900 date system.
Try using SumProduct, this just worked fine for me with a column of dates testing if they were in September:
=SUMPRODUCT(--(C3:C5>0),--(MONTH(C3:C5)=9))
I have a set of data that looks something like this:
11/8/12 5:20
11/7/12 15:57
11/7/12 13:51
11/7/12 10:47
11/7/12 8:00
Just in Excel, I want to be able to count the number of rows with 11/8/12, and the number of rows beginning in 11/7, etc. I have a pretty long list of dates and times, but I'm only interested in the dates.
I tried =COUNTIF(A1:A235, "<11/8/12 5:20") to get everything before 11/8, but obviously this doesn't work because I need to type in the time. Does anyone know how to:
1) make the timestamp irrelevant?
2) somehow search for rows that "contain" a certain date value and count up the rows that contain that value?
You can insert in a cell e.g. F7 the date which should be used
and then your formula will look like this
=COUNTIF(E8:E12;"<"&F7)
And then in case that your F7 will contain 11/7/12 14:00 the countif will return 3
NOTE: expecting the british date 11/7/12 is dd/mm/yy
EDIT: Date function
When I've seen another answer, I would like to show another approach, which is culture safe. Whenever we will put some strings representing dates, it could happen that a collague has different regional settings (e.g. British dd/mm/yy vs US mm/dd/yy)
That's why I placed the date into separated cell, representing the Date regardless of the culture. If that all have to be placed inside one cell, the correct approach is to use Date function
=COUNTIF(E8:E12;"<"&DATE(2012;7;11)+TIME(14;0;0))
In Excel dates are integers and the time is a fractional value so you can simply count between one date and the next (date +1) to get everything on a single date, e.g. for everything on 11/7
=COUNTIF(A1:A235, ">=11/7/12")-COUNTIF(A1:A235, ">="&"11/7/12"+1)
or in Excel 2007 or later you can use COUNTIFS
=COUNTIFS(A1:A235, ">=11/7/12",A1:A235,"<"&"11/7/12"+1)
for either one you can use a cell reference with the date as Radim suggests, i.e. with date in B1
=COUNTIFS(A$1:A$235,">="&B1,A$1:A$235,"<"&B1+1)
With that last version you can simply list all your dates in B1 down, and then use the formula in C1 copied down to get counts for each date
