We can use condtional formatting:

Say we have a list of dates in column A and we want to hi-light those that
are coming due within the next 72 hours:

Select A1 and pull-down:

Format > Conditional Format... > Formula is

=IF((A1-NOW())<72/24,1,0) and pick a distinctive format

Then copy the format down the column.
