I have a column A where I show my projects, then columns B to XX with days i.e.
A 1 B1 C1 D1
Project 8 July 9 July 10 July
how can I hide columns if the are older than today? (i.e. based on the above I only want to see column A and column D i.e.
A 1 D1
Project 10 July
note, I only want to hide the columns, not delete them
