If I understand you correctly (and I'm fairly sure I don't), this is what
you want:

=IF(O4="Saturday",IF(R4$T$25,TEXT(MOD($T$25-Q4,1),"hh:mm:ss"),TEXT(MOD
(R4-Q4,1),"hh:mm:ss")),"")

You said you needed to subtract the end time (in R) from the start time
(in Q), and you said R is already calculated. That threw me off because I
wasn't sure if R is supposed to be the end time or the difference between
the start and end times. I assumed the former in my calculation.

thanks for reply
sorry for ommiting some important points

ok here we go

Column Q is the time that the occurrence started
Comumn R is the time that the occurence ends
Column R is already calculated
i want to subtract the end occurrence from the start occurrence and
disregard any time occcurred if after 06:00:00
Saturday in column O is checking the day of the week as i only want
this to apply on a saturday morning.

right because you didn't mention such important things as where you
are getting the difference (is that already calculated in R), what
the purpose of column Q is (you listed it but don't seem to use it at
all), and what Saturday and column O have to do with anything.

The reason why your formula doesn't work is that what's in column R
cannot be simultaneously less than 05:59:59 and greater than 06:00:00
(that's what your AND is asking) so you will always get spit back
whatever is in column R.

hi
i am trying to calculate theamount o time between 2 time values

s25 = 05:59:59
t25 = 06:00:00

Q R
row 34 04:36:38 04:37:03
row 35 05:16:52 07:14:01

=IF(O34="Saturday",IF(AND(R34$T$25,R34<$S
$25),"06:00:00",TEXT(MOD(R34,1),"hh:mm:ss")),R34) returns
04:37:03




=IF(O35="Saturday",IF(AND(R35$T$25,R35<$S
$25),"06:00:00",TEXT(MOD(R35,1),"hh:mm:ss")),R35) returns
07:14:01

what i want is if the the time value in column R exceeds 06:00:00
the time is replace with 06:00:00
this works for row 34 but not row 35

any ideas where i going wrong
