Excel Auto Protect by Date Options

[cylenanichols]

I have an excel workbook set-up with each day of the month in a column. I am looking to have each day auto protect today and the next 2 future dates so no one can make changes.
Ex: At 12:01am and it is Friday morning. I want Friday, Saturday and Sunday columns to auto protect, allowing users to edit Monday and forward of the following week, and going forward each day to auto protect that day at 12:01am and the next two days.....

Thank you. I have tried allay to se this up.
