Excel: Counting how many rows fall within a time period

问题

I have an excel sheet with 2 columns

Column A = "CA", "CR" or "IN"

Column B = Date & time format DD/MM/YYYY HH:MM

I want to make a count at the bottom of a column for each row that has this criteria:

i) Row 1-8 = "CA"

ii) Row 1-8 needs to check for a time range, namely > "17:00" and < "04:59"

This is what I've come up with so far:

=COUNTIFS(A2:A8,"CA",B2:B8,RIGHT(TEXT(B2:B8,"hh:mm"),5)>"04:59"), B2:B8,RIGHT(TEXT(B2:B8,"hh:mm"),5)<"17:00")

I presume using a range within a the text function is wrong, but don't know how to resolve this.

Because Column B is in a date and time format, I'm having to change it to a string within the function so I can make a test on just the time - Maybe there's a better way?)

Thanks

The problem with COUNTIFS is that you can't manipulate the conditions a lot. You could insert a column containing the time only, in which case you could use COUNTIFS but if you cannot, you can use SUMPRODUCT for substitute:

=SUMPRODUCT((A1:A6="CA")*(((TEXT(B1:B6,"hh:mm")*1>TIME(17,0,0))+(TEXT(B1:B6,"hh:mm")*1<TIME(5,0,0)))>0))

This applies a few conditions on an example range A1:B6:

(A1:A6="CA") that ensures that the row has CA,

(TEXT(B1:B6,"hh:mm")*1>TIME(17,0,0)) that ensures that the time is above 17:00

(TEXT(B1:B6,"hh:mm")*1<TIME(5,0,0)) that ensures that the time is before 05:00 (You have 4:59 in your question, if you really meant less than 4:59 then change this part).

The + for the last two conditions 'OR's the two conditions, then the whole thing is 'AND'ed with the first condition.

This is difficult to do with COUNTIFS because you can't modify ranges with functions.....but you can do that with SUMPRODUCT - try this

=SUMPRODUCT((A2:A8="CA")*(MOD(B2:B8,1)<"17:00"+0)*(MOD(B2:B8,1)>"04:59"+0))

I'm assuming that you want between 04:59 and 17:00 - in your point ii) you show it the opposite way to what you have in your formula

MOD extracts the time from the date/time so it can be compared against a time range. If you are counting within a range including whole hours, e.g. 5 to 16 inclusive you can use HOUR function without MOD, i.e.

=SUMPRODUCT((A2:A8="CA")*(HOUR(B2:B8)>=5)*(HOUR(B2:B8)<=16))

回答3:

You do not need to deal with strings at all for the time. Excel provides with quite a few date&time functions, enough in your case.

A concise formula is

=SUMPRODUCT((A1:A8="CA")*(MOD(B1:B8,1)<=TIME(17,0,0))*(MOD(B1:B8,1)>TIME(4,59,0)))

Notes:

I assume you meant <=17:00, instead of <17:00. It is easy to modify the formula if I was wrong.
You used A2:A8, but you probably wanted A1:A8, as per the text. It is easy to modify the formula if I was wrong.
COUNTIFS is usually much less flexible than SUMPRODUCT (combined with other functions as MATCH, INDEX, SUM, etc.)

PS: as barry houdini points out, the OP asks for two opposite time ranges. I have chosen here one of them.
