How to make a Formula containing times.

S

Sapphyre

How can I make a formula calculate how many occurances of a specific time
frame happened in Sheet 1, column A, and put it in Sheet 2, column A, B, C?

Example of the colums I'm speaking of:

Sheet 1: contains start time of projects during 3 different shifts
A
START TIME (Header)
07/01/07 03:00
07/01/07 05:50
07/01/07 07:00
07/01/07 11:00
07/01/07 15:10
07/01/07 18:37
07/01/07 23:01

Sheet 2:
A B
C
7a-3p Shift (Header) 3p-11p Shift (Header) 11p-7a Shift (Header)
2 2
3

7a-3p=07:00 a.m. - 14:59 p.m., 3p-11p=15:00 p.m. - 22:59 pm., and
11p-7a=23:00 - 6:59 a.m.,

Any help would be appreciated.
Thank you.

Try:
=SUMPRODUCT((Sheet1!B3:B9>=--("7:00"))*(Sheet1!B3:B9<--("15:00")))
=SUMPRODUCT((Sheet1!B3:B9>=--("15:00"))*(Sheet1!B3:B9<--("23:00")))
=SUMPRODUCT((Sheet1!B3:B9>=--("23:00"))*(Sheet1!B3:B9<--("24:00")))+SUMPRODUCT((Sheet1!B3:B9>=--("0:00"))*(Sheet1!B3:B9<--("7:00")))

Adjust the ranges to suit your needs.

Ok, tried your formulas (just changed B range to A) for each column and it
didn't work. Not sure why. Could it be because in Sheet 1 column A I also
have dates?

Wrap the ranges in

MOD(range,1)=--"15:00"

etc


to get just times

Thanks for the replies. I think I might be over my head trying to get this
formula to work. I know just one wrong .,-() can mess up the whole thing and
not sure where exactly you wanted me to put MOD(range,1)=--"15:00" in the
formula. I will keep at it though :)....thanks again

I tried that Peo but I ran into rounding problems with MOD(range,1)=--"7:00"

With 7:00 in A1 and 07/01/07 07:00 in B1
=Mod(A1,1) -mod(B1,1) returns 6.79089E-10

=SUMPRODUCT((ROUND(MOD(Sheet1!A3:A9,1),6)>=--("7:00"))*(ROUND(MOD(Sheet1!A3:A9,1),6)<--("15:00")))

Returns the right answer, (rounding to 9 places does not), but I would not
be confident that it would in all circumstances.

It would be much better if the OP separated the dates and times in different
columns, which of course is what I had originally.

Thank you Sandy, I see now where you might have misunderstood my date/time.
They are both in column A, not date A and time B, that was my fault in my
original post, I should have clarified better.

Anyway, I think you are right in breaking up the date and time into 2
different columns. I have been trying to get data that my boss wants from a
spread sheet that was already in place when I started working there. Would
have been much easier to just start a whole new one from scratch, but it's
getting there.

Thank you for all your help.

If it doesn't mess up the rest of the sheet you can insert a new column B,
highlight the Dates & times in columns A and then select Data > Text to
Columns > Delimited > Next > check Space > Finish, reformat the columns to
what you want then use the original formulas.
