Hi !! I have a table as below :

Date Time IN Date Time Out No. of hrs
01/09/2008 23:30 02/09/2008 1:30 2.00
02/09/2008 22:00 03/09/2008 2:30 4.30
03/09/2008 23:00 04/09/2008 0:30 1.30
04/09/2008 0:20 05/09/2008 0:50 0.30
05/09/2008 1:00 05/09/2008 2:00 1.00
06/09/2008 2:00 06/09/2008 3:00 1.00
07/09/2008 3:00 07/09/2008 4:00 1.00
08/09/2008 4:00 08/09/2008 5:00 1.00

Each day i record the vehicle in & out time at the warehouse.
1.) How can i automatically calculate the no of hrs the vehicle was at the wh.
2.) A also need the total no of hrs for a select period.
3.) How do i calculate the average time vehicle reaches the wh for a period.
4.) How do i calculate the average time vehicle leaves the wh for a period.
Simple average is not giving the correct result for IN-TIME & OUT-TIME ,
since in some case there is a change in the dates as well. Vehicle come in
the night but leaves post midnight when the date has also changed.
Pls. help me with this problem.

Assuming your dates to be in format dd/mm/yyyy (otherwise your mechanics are
very slow!)
this formula =(D1-B1+(C1-A1))*24 computes the time for first vehicle
Excel treats time as a fraction of a day.
I get values 2. 4.5, 1.5, 24.5, 1, 1, 1, 1 where 4.5 is 4 and 1/2 hours (not
4 h 5 min)

In J1 I entered a date (01/09/2008) and in K 1 I entered another
(05/09/2008)
In L1 I used =SUMPRODUCT(--(A1:A8=J1),--(A1:A8<=K1)) to tell me how many
vehicles were in during that period (5)
The total time for that period is given by
=SUMPRODUCT(--(A1:A8=J1),--(A1:A8<=K1),E1:E8) ---the answers is 33.5
The average time is L1/M1 (6.7 hours)

Hi !! Thanks.
But, as desired in points 3 & 4,
i wanted the avergae IN-TIME & average OUT-TIME for the vehicles for a
select period.
And, simple avergae of column B & D does not give the correct avergae time,
because in some case the date changes.
If you could pls help me resolve this as well.
eg - if you average the data in column B, it gives - 9:51 (which doesnt make
any sense) since the vehicles are reaching the wh in the night.

I used the formula =A1+B1 in G1 to add time to date
Copied this down to G8
In G9 I used =AVERAGE(G1:G8) to get 04/09/2008 21:51

If you do not want to devote a column to this use the single formula
=AVERAGE(A1:A8+B1:B8)
but commit it with SHIFT+CTRL+ENTER not just ENTER. Also Excel will not know
this is a date/time so you will need to give it a format like dd/mm/yyyy
h:mm

Hi. Thx.

Just wanted to check that if i make it a point to give the format as
dd/mm/yyyy
h:mm , in the column B & D -

1.) Do i still need to mention the date separately in the column A & C ?
2.) Does the formula for calculating the no. of hrs =(D1-B1+(C1-A1))*24 ,
also need to be changed / amended , or should give the same results ?
