I have to assess my team of 70 every six months so if the 1st assessment is
01.01.06 then the next is due on the 01.12.06.

I now how to show the next date due by taking the cell +180 to give me the
next assessment date.

What I want to do is get a reminder 120 days (Coloured Green) from the
original assessment date and then a final reminder at 160 days(Coloured Red )
so I do not miss their assessments

I have tried to use conditional formating but I do not know how to get it to
work as each original assessment dates are different depending when they
joined the team.

How do I get Excel to calculate "X" amount of days forward and change colour
to give me a visual reminder without trawling through the spreadsheet.

Column E        Column F
Original Dates  Dates in six months time
