Excel - Placing values that fall within a certain time range - excel

Question

I have the following data on duration of particular services.
A B C D
Usage Start (Local time) Start Time Usage Until (Local time) End Time
03.03.2018 10:00 12:00:00 AM 03.03.2018 00:00 1:00:00 AM
03.03.2018 00:00 1:00:00 AM 03.03.2018 00:00 2:00:00 AM
03.03.2018 16:30 1:00:00 AM 03.03.2018 00:00 3:00:00 AM
And I want to count the number of times a timing falls within a certain range(eg. 00:00 - 01:00)
Start End Counts
00:00 01:00 1
01:00 02:00 2
02:00 03:00 1
03:00 04:00
04:00 05:00
05:00 06:00
What formula should I use and how do I apply it?
I have tried this
=COUNTIFS($B$2:$B$566,">="&A2,$D$2:$D$566,"<"&B2)
And this
=SUMPRODUCT(($B$2:$B$566>= A2)*($D$2:$D$566< B2))
But it doesn't account for more than 24 hour duration (Eg.3/3/2018 1:00 PM - 4/3/2018 2:00 PM, 25 hours)

Answer 1

It looks like you're ignoring the time portion in Columns A and C. Assuming your start/end hour bins are in columns F and G, the formula below will give you the number of times that an event passed through your first hour bin (you have to enter it as an array formula--ctrl+shift+enter). Fill down for subsequent hour bins.
=SUM(($B$2:$B$4<F2+TIME(0,30,0))+($D$2:$D$4>F2+TIME(0,30,0))+INT($C$2:$C$4)-INT($A$2:$A$4)-1)
This will count an event in an hour bin if the event is active at the half-hour mark.
If the event needs to cover the entire time bin, use this formula (again with ctrl+shift+enter):
=SUM(($B$2:$B$4<=F2)+IF(G2>F2,($D$2:$D$4>=G2))+INT($C$2:$C$4)-INT($A$2:$A$4)-1)

Answer 2

Was a bit more complicated than I expected, but I got it to work.
Though before we start, you need to format your table a little. You
can't have date and time in the same cell (as excel has trouble
recognizing storing two formats in 1 cell).
Instead format your table
like so:
Next we should create some hidden rows (technically you can stick what I'm about to do in 1 giant formula, but for sake of clarity I prefer hidden rows)
First we focus on the time difference in hours. Creating the two following columns
Also, make sure, you set the format in these newly added rows to
number. Technically it will work without it, but it will look
confusing to human eye
In the Time defference we use the following formula
=ABS(F2-C2) * 24
In the overnight h column:
=IF(C2>F2, 24-G2, G2) This is utilized that we properly count with transition dates (eg. 23:00 1/1/18 -> 01:00 2/1/18) we don't want to add the extra 24 hours in this case.
That would be the hours fully working, but we also need to ensure the
formula works, when there's more than one night of difference (eg.
1/1/18 -> 3/1/18)
Next, we add these these two rows
In the date difference column, as the column name suggests
=DATEDIF(A2, D2, "d") * 24
Last but not least, the overnight delta is basically the same principle as overnight h, but with dates instead of hours
So now, if we have hidden the rows, added the following formula to result =H2+I2-J2 we get our sought after table:
Which corresponds with the expected result! :)
EDIT: If you don't want to take hours into cosnideration and only count how many times an interval of 24 hours has expired use the following formula
=IF(C2>F2, DATEDIF(A2, D2, "d")-1, DATEDIF(A2, D2, "d"))
(under presumption c2,f2,a2,d2 are in the columns as in my original table i provided)
