Conditional formatting based on time (00:00:00)

Copper Contributor

Please can you help me find a solution to the following question?
I keep a record of what time the user updates data. The allowed time is one hour before and one hour after the allotted time. Let's say we assign 9:00:00 as the indicator, so:
08:00:00 to 09:59:59, the cell should be green,
Every other hour, orange cell,
No update, red cell

Let's say the times will be entered in B2:B100.

Select this range. B2 should be the active cell within the selection.

Set the Fill Color to red. This will be the default.


On the Home tab of the ribbon, click Conditional Formatting > New Rule...
Select 'Use a formula to determine which cells to format'.
Enter the formula




Click Format...
Activate the Fill tab.
Select orange.
Click OK, then click OK again.


Repeat these steps, but with the formula




and green as fill color.

Thanks for your help, but it doesn't work for some reason. I'm doing something wrong, but I'm not sure what. Please, here is step by step of my work, maybe you can see something?

Perhaps column D contains date + time values instead of just time values. Does this formula for the "green" rule work?



Thank You Hans
