# How to Calculate if a Range of Times Falls Between two Date/Time S

M

#### Michaniker

I have a problem where I am tracking maintenance workers who forget and do
not clock out for supper. Supper time is between 18:00 and 18:30 hours
daily. I couldnâ€™t figure out how formulate if a time range (18:00 - 18:30)
fell between two Date/Time stamps so I compromised figuring if I could
illustrate that his time card showed he was still clocked in during the
middle of the supper mealtime, I would be able to confront him and remind him
of the need to clock out.

Row H is the Start Date/Time

Row I is the Stop Date/Time

Row J contains:
=IF(AND(MOD(H1,1)<TIMEVALUE("18:15"),MOD(I1,1)>TIMEVALUE("18:15")),"Worked
During Supper","")

This works most of the time. But when row H is 12/14/2009 16:00 and row I
is 12/15/2009 01:05, I get a blank. I should see â€œWorked During Supperâ€.

a. What am I doing wrong?
b. How could I expand the formula to include checking for the full time
range (18:00 - 18:30)?

Thanks,
Michaniker

Hi

Try this:

=IF(H2-INT(H2)<=TIMEVALUE("18:00"),IF(OR(I2-INT(I2)>=TIMEVALUE
("18:30"),INT(I2)>INT(H2)),"Worked During Supper",""),"")
