Help with a conditional formula with multiple conditions

I used conditional formatting similar to this on a spreadsheet where I wanted to know, in advance, if a renewal date was approaching. You will Todays Date somewhere in the sheet as a constant update and then conditionally format the cell showing the target date using "In the next month" category, highlighting them in red or another colour. This will tell you cells/people that will become overdue so you have time in advance to remedy the issue. You can use similar styles to look at overdue, ie.dates past if you wish, changing the choice to greater than, less than, etc.
