I have a spreadsheet that shows the employees who have masks assigned to them. They are to have yearly annual services, I would like for those who are out of test date to show in red, those who are in test date in green and for it to change colour to amber when they are 1 month from being out of test date. I would like this to automatically update each year Is there a way that I can get it to recognise the older dates and calculate with todays date to show the out of date one's and also the current in date ones? This is an example of how the spreadsheet is currently
