I have a spreadsheet for tracking employees hire dates, absenses, etc. I
would like for the column with each person's hire date (Column H) to turn red
a week before their anniversary date to alert me to give them a review. The
column next to it (Column I) is where I will fill in the date that the review
was done.

How can I format these two column so that 1) the cells in the date of hire
column turn red a week before their anniversary date, and 2) so that when the
reviewed date is entered the cells changes back? Please help!! This may get
me a raise!!!
