I need to come up with a formula that will count the number of rows of a date column. I need greater than 365, 300-365, 299-230 ect all the way down to 30 days. One formula for each will be perfect and as long as I can figure out the first couple, I can get the rest. Help is much appreciated.
The date format in the excel table is: 9/1/2021
A year or older. Seems this may be close but it's giving an error
=COUNTIF(A1:A1000,">="=DATE(YEAR(=TODAY()-1)))
=COUNTIFS(A1:A1000,">="=DATE(DAY(=TODAY()-364)),A1:A1000,"<="=DATE(DAY(=TODAY()-300)))
More than 365 days ago:
=COUNTIF(A1:A1000,"<="&TODAY()-365)
300-365 days ago (need countifs in order to do multiple criteria)
=COUNTIFS(A1:A1000,">="&TODAY()-365,A1:A1000,"<="&TODAY()-300)
Think about using Frequency - this works in most versions of Excel, but has to be array-entered in non-365:
=FREQUENCY(A2:A1000,TODAY()-C2:C11)
The bin values can be entered into the sheet as below or expressed as an array constant in curly brackets. Note that each bin includes values less than or equal to the corresponding cut-point, so the first value is 366:
If all bin sizes were equal, you could use Sequence in Excel 365 to generate the bin ranges.

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$5,">="&A11)
Excel formula stop working after x number of rows
A similar question was posted 4 years ago. There were two answers. I have reviewed both. The first response is excellent but it is not the cause of my issues. The second answer was a statement that the person who responded had the same issue and what he or she did to solve it which will not work in my case. There was no explanation as to why the problem occurred.
Here is my problem. I am using the following formula:
IF(MONTH(MDB.xlsx!Date)=7,SUMIFS(MDB.xlsx!_910,MDB.xlsx!Activity,"MGRINC",MDB.xlsx!AcctNum,$Y202),0)
MDB is a Master Data Base. It currently has 214 rows but will grow substantially to probably around 5000 rows. The named ranges in the MDB are currently defined as rows 1 to 500. The above formula is in a spreadsheet, with about 300 rows. The formula works fine through row 201. From 202 on, it only returns zeros.
This is what I have done:
I have looked at constituent parts of the formula using F9, all values and arrays are reporting correctly. (That’s why the defined name range is currently set to only 500 rows, so I can breakdown a formula using F9 and not get an error after 8,192 characters.)
If I move the line with this formula from line 202 to an earlier row, it works fine.
If I delete earlier rows, the formula works fine.
This appears to be a memory issue of some sort but I don’t understand why. I have built larger and much more complex spreadsheets some of which take minutes to calculate with no issues.
Any thoughts?
Extracting the Month inside a Sumif will not work. You could add two conditions, one testing for the date being greater/equal to July 1, the second testing for the date being smaller/equal to July 31.
=SUMIFS(MDB.xlsx!_904,MDB.xlsx!Date,">="&date(2020,7,1),MDB.xlsx!Date,"<="&date(2020,7,31),MDB.xlsx!Activity,"MGRINC",MDB.xlsx!AcctNum,$Y202)
Or, you could add a column to your source data that has the month number, then test for that month number
Or, you could change the formula to use SumProduct instead of Sumif, incorporating the month filter into the SumProduct parameters like this:
=Sumproduct((MONTH(MDB.xlsx!Date)=7),--(MDB.xlsx!Activity="MGRINC"),--(MDB.xlsx!AcctNum=$Y202),MDB.xlsx!_910)
With the formula just testing form Month number, the year is disregarded, so if you have data spanning multiple years, you may want to add a parameter that checks the year.
Note that all these formulas are regular formulas and do not need to be array entered.
I am trying to find the minimum date in a row that has both dates and number data types. I tried to use the MINIFS function but that still produces the number value as the minimum, rather than the date. I am restricted to doing this as an in-cell function, rather than in VBA. Also, the data structure is a bit wonky, I know, but it can't be changed.
=MINIFS(A2:C2,A2:C2,CELL("format",A2:C2)="D4")
When I enter =MIN(IF(A6:C6>40000,A6:C6)) I get a #Value error. Excel doesn't like the range before the > symbol.
Remember that dates in Excel are calculated as number of days starting from January 1st, 1900.
Thus, if you look at your dates as numbers, you will see that it's in fact a number '44042'.
Knowing that, you can use MIN together with IF formula:
=MIN(IF(B5:D5>43831,B5:D5))
Where your suggested numbers are in cells B5:D5 and '43831' is 2020/01/01.
Of course, if you have numbers with high values, this solution should be adapted.
Here's a screenshot I made:

I have two columns of dates. One is the move in date and the other the move out date. I want to figure out how many days the tenant was there during a second date range. for example: how many total "bed days" did we have in the month of July? 7/1/2016-7/31/2016
This function calculates the number of days each tenant was there each month but I would like it if I could get the entire calculation into one cell without creating a dummy column for each month.
=MAX(0,MIN(EOMONTH($B$2,0),I14)-MAX($B$2,H14))
I tried to change a few things and use it as an array function but it is not working. I am very new to array functions so I may be doing it completely wrong.
=SUM(MAX(0,MIN(EOMONTH($B$2,0),I:I)-MAX($B$2,H:H)))
any help is much appreciated! Let me know if you need more info too.
Bad news - you can't use MAX and MIN in an array formula like this because instead of treating H and I as two arrays it just treats them as one big long array and you only get one value out of them.
You also need to add 1 to your original formula because if they moved in on the last day of the month (say) it should still count as one day.
If you replace the MAX and MIN with IF statements you get something like this
=SUM(IF(IF(EOMONTH($B$2,0)<IF(I2:I10="Active",TODAY(),I2:I10),EOMONTH($B$2,0),IF(I2:I10="Active",TODAY(),I2:I10))-IF($B$2>H2:H10,$B$2,H2:H10)<0,0,
IF(EOMONTH($B$2,0)<IF(I2:I10="Active",TODAY(),I2:I10),EOMONTH($B$2,0),IF(I2:I10="Active",TODAY(),I2:I10))-IF($B$2>H2:H10,$B$2,H2:H10)+1))
which has to be entered using CtrlShiftEnter
A useful tip if you are new to arrays is not to include more rows in an array formula than you need to because it will be slow, and test it first on a small number of rows so that you can step through it using Evaluate Formula if you run into trouble.
I have excel data in the following format
Date Amount
01-Jan-16 23.94
12-Jan-16 17.96
26-Jan-16 32.92
03-Feb-16 38.90
20-Feb-16 62.27
26-Feb-16 45.89
I would like to sum the amount field for specific months, that is I would like to sum up the amount in January and also in February separately.
This is the code I have tried thus far which I found in a previously asked question (see Excel Formula to SUMIF date falls in particular month).
=SUM(IF(MONTH(A:A)=1,B:B,0))
It works for January but when I change 1 to 2 it returns zero.
=SUM(IF(MONTH(A:A)=2,B:B,0))
Would sumifs work better?
Here are two other ways of doing it:-
=SUMPRODUCT((MONTH(A2:A10)=1)*B2:B10)
and
=SUMIFS(B2:B10,A2:A10,">="&DATE(2016,1,1),A2:A10,"<"&DATE(2016,2,1))
Change as necessary to get totals for other months.
I have put the results next to the original array formula in this screen shot:-
Use specific range rather than full column. You must use the formula as array formula.
=SUM(IF(MONTH($A$2:$A$1000)=1,$B$2:$B$1000,0))
Press CTRL+SHIFT+ENTER to evaluate the formula as array formula.
