Time band hour count

[Peter1973]

I am looking for a formula to look in times in A1 and A2 (A1 has start time and A2 has finish time and tell me how much of that time crosses over the hours between 1800 and 0600
Example
A1 = 2200 A2= 0800 answer would be 8 hours

Any help appreciated

If you have time values in cells A1 and A2 (22:00 and 08:00), try

=(1-MAX(A1,18/24)+MIN(A2,6/24))*24

If you have four-digit numbers (or text strings) in cells A1 and A2, try

=(1-MAX(TEXT(A1,"00\:00"),18/24)+MIN(TEXT(A2,"00\:00"),6/24))*24

Hi, I think below should work:

=IF(A2>=A1,A2-A1,A2+1-A1)

Given values are in excel time format.

Thanks they don’t seem to work out the hours between 18:00 and 06:00

Seems to be working for me:

Book1
	A	B	C
1	18:00:00		12:00
2	6:00
Sheet5

Cell Formulas
Range	Formula
C1	=IF(A2>=A1,A2-A1,A2+1-A1)

is your data in excel date-time format or stored as text ? can you check by using ISNUMBER on time field and see if it gets FALSE.

This counts the total hours whereas i only want to count hours that are between 1800 and 0600 ie if A1 was 2100 and A2 0900 the answer would be 09:00 and the hours from 0600 to 0900 would not be counted.

Thanks

Below should work, in this case if A1 is 05:00:00 and A2 is 06:00:00 then the result will be 01:00:00 but if A1 is Greater than A2 then you will get your desired result. Assumption here is that in cell A1 & A2 you have only time values (with general number format these should be less than 1).

Book1
	A	B	C
1	18:00:00		6:00:00
2	6:00:00
Sheet1

Cell Formulas
Range	Formula
C1	=IF(A2-A1<0,A2,A2-A1)

Have you tried formulas offered in Post # 2?
