lock spreadsheet by date

[Carl]

Is there a way that I can password protect a workbook so that it will lock
all within a set time frame?

 

[Dave Peterson]

Not with any real assurance.

Almost anything I would do would rely on macros and macros can be disabled.

 

[Carl]

Do you have any suggestions on how I could do something of a similar natire?

 

[Dave Peterson]

Nothing that would actually work in all cases.

You could add a routine that would lock the sheets if after a certain date. But
that protection is easily broken.
