计算当前月份的日期值-MS Excel

Question

I have following date values (with time) in Column A.

1/1/2012 8:50  
1/1/2012 8:45  
1/1/2012 8:55  
1/1/2012 8:59  
1/1/2012 8:12  
3/1/2012 8:30  
1/1/2012 9:50  
2/1/2012 10:00

Now, I want to get a count of cells from Column A having date values of current Month.

I have thought of following formula, but I suspect it will work only in machines having mm-dd-yyyy as System-Date-Format.

=COUNTIFS(A:A,">="&DATEVALUE(MONTH(TODAY())&"-1"&"-"&YEAR(TODAY())),A:A,"<"&DATEVALUE(MONTH(TODAY())+1&"-1"&"-"&YEAR(TODAY())))

Any workaround/trick for this?

Answer 1

Try this: =SUM(IF(MONTH(TODAY())=MONTH(A:A),1,0)) , but press CTRL + SHIFT + ENTER instead of usual ENTER - this will define an ARRAY formula and will result in {} brackets around it (but do NOT type them manually!).

Put the formula in ANY cell you like.

Answer 2

您可以像这样在当月使用COUNTIFS

=COUNTIFS(A:A,">="&EOMONTH(TODAY(),-1)+1,A:A,"<"&EOMONTH(TODAY(),0)+1)

Answer 3

An alternative to the array formula would be to use SUMPRODUCT() :

=SUMPRODUCT(--(MONTH(A:A)=MONTH(TODAY())))

The -- part is necessary: it turns an array of TRUE/FALSE values into numbers. The double-negative is needed to get a positive value: =VALUE(TRUE) gives an error, =VALUE(-TRUE) gives -1 , so =VALUE(--TRUE) gives +1 .
