Use Conditional Formatting.

1. In design view of your form/report, click the date text box with the
mouse, and choose Conditional Formatting on the Format menu.

2. Add the conditions you need. For example, to make the control named "d"
go red if date has already passed, set Condition 1 to:
    Expression         [d] <= Date()
and choose the color you want.

3. Add other conditions (up to 3.)
For example, the expression:
   [d] < Date() - 30

I think this will do what you need.Tou'll need to set the colors as you like.
For each Condition you use

Expression Is

Then enter the code for each condition, exactly as shown (the Conditional
Formatting is VERY PICKY!)

16-30 days in future

[CalibrationDate]>DateAdd("d",+15,Date()) And [CalibrationDate]<DateAdd("d",
+31,Date())

15 days in future

[CalibrationDate]>Date() And [CalibrationDate]<DateAdd("d",+16,Date())   

Overdue
