Subtracting 24hr clocks?
HI, HELP!
I'm trying to generate the formula to subtract 24hr time clocks. If I want to work out the hours between 0500 and 1600 then it's a simple case of subtraction - however, the problem is when I try and reverse this. I'm trying to calculate a formula to work out the hours between, for example, 1600 and 0630 - the formula I've tried using doesn't work so is obviously wrong. Please help! |

Subtracting 24hr clocks?
Hi Stefi,
This doesn't seem to work?! I'm trying to work out the hours between 1600 (start) and 0800 (end) but it's coming out with a minus figure. Is there any way I can do this? Thanks Clare "Stefi" wrote: start time:A9 end time:B9 =B9+IF(A9B9,1,0)-A9 Regards, Stefi €˛devoted_darling€¯ ezt Ć*rta: HI, HELP! I'm trying to generate the formula to subtract 24hr time clocks.

Subtracting 24hr clocks?
I have a guess: 1600 (start) and 0800 (end) suggests that your data are not
of real Excel time format but text strings, otherwise they would look like 16:00 (start) and 08:00 (end). Am I right? Stefi €˛devoted_darling€¯ ezt Ć*rta: Hi Stefi, This doesn't seem to work?!

Subtracting 24hr clocks?
Hi Stefi, yes that's correct. They are currently in text format - do they
need to be changed to time format for this to work?

Yes, convert them with this function:
=TIMEVALUE(LEFT(A1,2)&":"&RIGHT(A1,2)) and format the result cells like "hh:mm"! Use David's formula because it's nicer! Regards, Stefi €˛devoted_darling€¯ ezt Ć*rta: Hi Stefi, yes that's correct.

Subtracting 24hr clocks?
Hi David,
Thankyou for your reply, however the formula brings back 0 when it whould bring back a number as it's calculating the hours worked between the 2 hours posted..... Any ideas?

I wonder whether you entered your times correctly? Remember that Excel
times are entered as 16:00 and 06:30, not 1600 and 0630. -- David Biddulph "devoted_darling" wrote in message ...

Hi David,
yes the times have been entered incorrectly - unfortunately I'm working from someone elses data so they have been entered as 1600 instead of 16:00. I'll change them and try again!

To convert your incorrectly entered times, use =--TEXT(A1,"00\:00") and
format as time appropriately. -- David Biddulph "devoted_darling" wrote in message ...
