Can Excel Let me know when a date passes?

[D1684]

I don't know if Excel can do this....

We have contractor sign in sheets in Excel. In the cell next to the person's name, we have tie date their MSHA certification expires. If you can visualize it, like this:

Name MSHA expires Time In/Out

John Smith 01-01-2007 05:00/13:00

Is there a formula I can use to notify me when the date passes?

For example, John Smith has an MSHA that expires on Jan. 1st.. Is there a formula I can put in the "MSHA expires" cells so that they change color, or some kind of message pops up on Jan. 2nd? When you have about 400 names on 30 sheets, it would make it easier.

Like I said I don't know if Excel can do this, but it's Excel has always suprised me every single time I've asked a question like this.

Thanks in advance for your aswers.

Try using Conditional formatting.
Select the Column with MSHA expires and through Format>Conditional Formatting> and give the condition1 as Cell Value is [less than][=today()] and change the pattern of the cell (through Format>Patterns, on the dialog box) to some color as you desire.
The box brackets just represents two boxes in the Conditional Formatting dialog box.
