Conditional Format a date column based three other date columns

Question

I have a date column (Start Date) that I want to conditionally format based on its relationship to three other date columns (Due Date, Due Date -3mo, Due Date -5mo).

If Start Date is *<*Due Date -5mo, format Green

If Start Date is between Due Date -3mo & Due Date -5mo, format Yellow

If Start Date is > Due Date -3mo, format Red

Basic Conditional Formating options require I pick a static date for the whole Start Date column.

Hi @Andrews, Rob ,

You can use this Json code to format the Start Date column.

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "div",
  "style": {
    "background-color": "=if(Number([$DueDate_x002d_5mo])-Number(@currentField)>0 ,'Green', if((Number(@currentField)-Number([$DueDate_x002d_5mo])>0 && Number([$DueDate_x002d_3mo])-Number(@currentField)>0), 'yellow', 'red'))",
    "color": "black"
  },
  "txtContent": "@currentField"
}

The running result is as below:
