Solved: Quarter Hours?

[TrippyTom]

Hi everyone,

I would like to setup some conditional format to highlight if a TIME entered is on the quarter hour (i.e. 12:15pm, 12:30pm, 12:45pm, 1:00pm, etc.).

I was thinking I could use MOD but time is really just a decimal, so how would you do something like this?

Hi

You could use a conditional formatting formula of:

=MOD(A1*24,0.25)=0

Assuming the time was in A1.

Perfect!

Thanks Richard.

actually, it's not fully working for some reason. I'm getting odd results (not 0) on some of my rows. I tried to post a screenshot but when I try to paste the code from HTMLmaker it shows up as CODE, not the worksheet.

[edit] -- I changed the formula to highlight if it's NOT a quarter hour
=MOD($C2*24,0.25)<>0

Ok can you describe what these cells contain that are returning odd results? Are they hardcoded values or do they contain a formula? If so, what is the formula?

It would be useful to actually write the formula that I provided in a worksheet cell, so that you can examine all the calculation steps to determine why the unexpected result is being returned.

Trying to attach an image of what i'm getting. In the image below, I would expect only rows 9, 10 and 12 to be highlighted.

What are the times being generated from? Are they exact times or is there maybe a second component that is obscured by formatting? You could attach a small sample of your workbook - I think that would make things a bit easier for me/others to debug.

ok hope this attachment works...

Try this formula

=MOD(MINUTE(C2),15)=0

Hey, it worked.
Thanks guys.
